SAFETY INFORMATION
ELECTRIC POWER
1 Power Sources - Connect this unit only to power sources specified in the Operating Instructions, and as
marked on the unit.
2 Polarization - As a safety feature, some units are equipped with polarized AC power plugs which can
only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into
an outlet, turn the plug over and try again. If it still does not easily insert into the outlet, please call a
qualified service technician to service or replace the outlet. To avoid defeating the safety feature of the
polarized plug, do not force it into a power outlet.
3 AC power cord - When disconnecting the AC power cord, pull it out by the AC power plug. Do not pull
the cord itself.
•
•
Never handle the AC power plug with wet hands, as this could result in fire or shock.
Power cords should be routed to avoid being severely bent, pinched, or walked upon. Pay particular
attention to the cord from the unit to the power socket.
•
Avoid overloading AC outlets and extension cords beyond their capacity, as this could result in fire
or shock.
4 Extension cord - To help prevent electric shock, do not use a polarized AC power plug with an extension
cord, receptacle, or other outlet unless the polarized plug can be completely inserted to prevent exposure
of the blades of the plug.
5 When not in use - Unplug the AC power cord from the AC outlet if the unit will not be used for several
months or more. When the cord is plugged in, a small amount of current continues to flow to the unit,
even when the power is turned off.

GETTING THE MOST FROM THE NAD T 744
Thank you for choosing NAD.
The T 744 A/V Surround Sound Receiver is a technologically advanced and highly capable product — yet we
have invested great effort in making it simple and easy to use. The T 744 delivers a range of genuinely
useful options for surround sound and stereo listening alike, using powerful digital signal processing and
superbly accurate digital-audio circuitry. However, we have also been careful to ensure that the receiver is
as musically transparent and spatially accurate as possible, incorporating much of what we’ve learned from
a quarter-century’s experience designing audio and home-theater components. As with all our products,
NAD’s “Music First” design philosophy guided the T 744’s design, such that it can confidently promise you
both state-of-the-art surround home-theater and audiophile-quality music listening for years to come.
We encourage you to take a few minutes now to read right through this manual. Investing a little time here
at the outset might save you a good deal of time later, and is by far the best way to ensure that you make
the most of your investment in the NAD T 744, and get the most from this powerful and flexible home-
theater component.
One more thing: We urge you to register your T 744 ownership on the NAD Worldwide Web site:
For warranty information contact your local distributor.

UNPACKING AND SETUP
WHAT’S IN THE BOX
Packed with your T 744 receiver you will find:
•
An AM loop antenna
•
•
•
•
A FM ribbon-wire antenna with balun
A removable AC cable (if you wish, any IEC-standard AC cable of suitable wattage may be substituted).
The HTR 2 remote control with 4 (four) AAA batteries.
This owner’s manual.
Save the packaging
Please save the box and all of the packaging in which your T 744 arrived. Should you move or otherwise
need to transport your receiver, this is by far the safest container in which to do so. We’ve seen too many
otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that
box!
CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will
provide a clear line of sight, within 25 feet/8 meters, between the receiver’s front panel and your primary
listening/viewing position—this will ensure reliable infrared remote control communications. The T 744
generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly
possible to stack the T 744 atop other components, but the reverse usually should be avoided. Nonetheless,
it is generally preferable that the T 744 stand alone. It is especially important that sufficient ventilation be
provided; if you are contemplating locating the T 744 within a cabinet or other furniture, consult your NAD
audio/video specialist for advice on providing adequate airflow.

ABOUT THE T 744
Though the T 744 is among the most technically sophisticated A/V receivers, we worked hard to make it one
of the most musically transparent home-theater components available as well; this is what we mean by
NAD’s “Music First” design philosophy. Here are just a few examples:
•
•
NAD’s exclusive Soft Clipping™ circuitry further enhances sound quality and dynamic potential.
High-performance components used throughout the receiver’s analog audio circuits maximize quality from
all sources, including multichannel analog sources such as DVD-Audio and SACD.
•
•
•
Preamp output (all channels) and main-amp input jacks make potential expansion as flexible as possible.
A Second set of Speaker terminals (Speakers B) for remote listening.
Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.
E.A.R.S. AND DIGITAL SURROUND
A key element of the T 744’s unique musical aptitude is NAD’s proprietary Enhanced Ambience Recovery
System (EARS). In sharp contrast to many “ambience-synthesis” music-surround modes, EARS exploits the
T 744’s substantial DSP power to route the ambient content that is “encrypted” in virtually all natural-
acoustic recordings to the appropriate main, center and surround speakers, without resorting to artificially
generated reflections or regeneration. EARS’ natural ambience yields a subtle but exceptionally effective
surround mode that naturally enhances the spatial presentation in a fashion suitable for serious music
listening. Dolby ProLogic II Music and DTS Neo:6 Music modes can also create enjoyable experience from 2-
channel sources.
On the digital side, the T 744 combines extraordinarily high-speed DSP processing employing one of the most
advanced high-speed DSP “engines” available, with fully 24-bit, 96 kHz-sampling-capable D/A converters
for all channels. A single, high-precision master clock synchronizes all digital circuits to eliminate the timing
errors (“jitter”) that otherwise compromise sonics. The result is legitimately state-of-the-art surround
decoding from Dolby Digital and DTS sources, with genuinely superior sound quality in all modes.
EASE OF USE
Despite the effort NAD has invested in the T 744 receiver’s sonic performance, we expended no less in
making it powerfully easy to use. Its design is uniquely simple for so sophisticated a component, and the HTR
2 universal remote control is equally understandable, as are the T 744’s own front-panel and on-screen
displays. Its simple yet powerful system of “presets” permits you to fine-tune your listening setup for
different conditions, sources, or listeners, and to recall these multiple parameters with a single keypress.
INTEGRATION
The T 744 receiver offers extensive, flexible system-integration options through its configurable DC trigger
outputs and input, and its standard-protocol IR communications links.

ABOUT THE T 744
UPGRADABILITY
The T 744 receiver permits flexible system growth via individually accessible pre-out and main-in jacks for
three channels, enabling external amplifiers to be used for any of these while still maintaining utility of the
receiver’s on-board power-amplifier channels for additional channels, remote-room links, or any other
suitable purpose.
ABOUT THE HTR 2 SYSTEM REMOTE CONTROL
Packed with your T 744 is the NAD HTR 2 remote control, a full-system remote especially designed to be easy
to use and easy to understand. Be sure to read the section “Using the HTR 2 Remote Control”, to familiarize
yourself with the remote’s layout and operations before proceeding to setup your A/V receiver.
Chances are, you will want to use your HTR 2 as your primary way to command your entire A-V system. The
HTR 2 can be employed to operate additional NAD or other-brand components such as a DVD/CD player,
television, satellite/HDTV tuner, VCR, or virtually anything else that operates via standard infrared remote
control.

Connect your DVD player’s composite video or S-Video output to the T 744’s corresponding DVD input.
(S-Video cable not supplied)
Connect the DVD player’s optical digital output to the T 744’s optical DIGITAL IN 1 input.
(Optical cable not supplied).
Connect your left and right front speakers to the T 744’s FRONT L and R outputs, being sure to connect
red to red (“+”) and black to black (“-”), with care to avoid stray wires or strands crossing between
terminals. (Connect center, surround, and surround-back speakers as well, if you like). If your system
includes a powered subwoofer, connect the T 744’s AUDIO PRE-OUT SW1, 2 or both jacks to its line
inputs.

Press in the main power switch (black pushbutton) on the T 744’s rear panel (this puts the T 744 into
STANDBY mode and illuminates an amber LED to indicate it is ready to receive remote commands), then
use the HTR 2’s [ON] key to power up the receiver. Be sure the TV/monitor is powered up, with the correct
input selected.
Start playback of the DVD player. Press the HTR 2 remote’s [Amp] Device Selector key, and then its (red)
DVD/numeric 1 key to select the DVD input. You should hear multichannel or stereo sound, and see an
image on the TV/monitor. (If one or the other fails to appear, you may need to use the receiver’s on-screen
menu system to check assignment of audio, video, and digital inputs; see “Setting Up the T 744”.)
Enjoy the movie or music, but be sure to set aside time to read this manual thoroughly, and to set up,
calibrate, and configure your T 744 carefully and completely.

STANDBY SWITCH: Pressing this key, or the HTR 2 remote’s [ON] button, will switch the receiver on, making it operational, changing the amber
Standby indicator to green and illuminating the VFL display.
STANDBY LED: Illuminates amber when the T 744 is in Standby mode; green when it is powered on; and flashes momentarily to indicate infrared
commands received from the HTR 2 remote. Protection Mode is indicated by a red illumination, and indicates that there is a problem with your set-
up or the unit itself. When the fault is removed, normal operation can be resumed (this may require turning the unit off and on again). This indicator
will be steadily dark only when the main POWER switch (REAR PANEL No.10) is switched off (or the receiver is unplugged from the AC supply).

AM/FM: Press to toggle between the tuner’s AM and FM bands.
DISPLAY: Press to display the channel mode of the currently selected source (other than the internal AM/FM tuner), in the format “front/rear/LFE.”
For example, a Dolby Digital or DTS 5.1-channel source will display 3/2.1. Note that the display shows signal channels, not speakers; for example,
a 2-channel analog or digital source (whether stereo or surround-encoded) will show 2/0.0, even though the receiver’s <Speaker Settings> may
indeed be set up to use the subwoofer with all sources, and the current Listening Mode may employ center and surround speakers.
When the AM/FM tuner is the selected input, sequentially pressing DISPLAY shows the currently tuned station’s RDS data, toggling between the
current station’s Radio Text and Station Name displays (see Listening to Radio, below).

PRESETꢀꢁ: Press to step up or down between radio presets; 30 FM and 10 AM station presets are available. Note that this function “wraps”:
Pressingꢁwill step from Preset 30 to Preset 1, or vice versa using theꢀkey. “Unused” presets are skipped over. (Note that Presets must previously
have been stored; see “Listening to Radio,” below.)
SEARCHꢀꢁ: Press momentarily to step up or down between FM or AM frequencies. Press and hold SEARCHꢀꢁfor more than 2 seconds to
search up or down; the T 744’s tuner will stop at the next sufficiently strong signal it encounters. Note that this function, too, “wraps,” and will
continue searching up or down from one end of the AM or FM band to the other.
Note that: SEARCHꢀꢁtunes the FM band by 0.05 MHz steps (twice the precision of most tuners and receivers). On the AM band, SEARCH
ꢀꢁmoves by 10 kHz or 9 kHz steps. To change the step amount, hold in the FM MUTE/MODE and AM/FM keys simultaneously.

ATTENTION!
Please make all connections to your T 744 receiver with the unit powered off or unplugged. (It is also advisable to power-down or unplug all
associated components while making or breaking any signal or AC power connections.)
1
FM & AM ANTENNA: The supplied wire “dipole” FM antenna will connect to the FM connector using the supplied “balun” adapter. It will usually
work best when mounted on a vertical surface such as a wall, with arms fully outstretched forming a horizontal “T” perpendicular to the origin point
of the signal. Experiment with placement and orientation of to yield the clearest sound and lowest background noise. In areas of difficult FM
reception an external FM antenna can yield dramatic gains in quality; consult your NAD audio specialist or a professional antenna installer.
The AM loop antenna supplied with the T 744 (or a suitable replacement) is required for AM reception. Open the clip terminal lever, insert the wire
and close, ensuring that the lever locks the wire in place. Testing different positions for the antenna may improve reception; vertical orientation will
usually produce the best results. Antenna proximity to large metal objects (appliances; radiators) may impair reception, as will attempts to lengthen
the wire to the loop.
NOTE: An external AM antenna can improve long-distance reception substantially; consult your NAD audio specialist or a professional antenna
installer. Do not connect anything other than a loop antenna to the AM ANTENNA terminal. Do not remove the AM loop antenna.
2
MONITOR OUT: Connect to video input of the monitor/television, using quality dual-RCA and/or S-Video cables designed for video signals. In general,
the S-Video connection is superior and should be used if your TV/monitor provides the corresponding input.
NOTE: The T 744 “transcodes” S-Video to composite-video signals, so that S-Video signals connected to the DVD, SAT, VCR, and VIDEO 4-6 inputs
will be present at both the S-Video and composite MONITOR OUT jacks when any of these inputs is selected. This provides the convenience of
requiring only a single video connection (usually S-Video) between the T 744 and the TV/monitor.
3
4
CD: Connect the analog stereo audio output from a CD player or other line-level audio source to this input.
DIGITAL IN OPT 1-2; COAX 3-6: Connect to the coaxial S/PDIF-format digital outputs of sources such as CD or DVD players, HDTV or satellite tuners,
or other components; connect DIGITAL IN OPT1-2 to optical S/PDIF-format digital outputs.
5
SOFT CLIPPING: Enables NAD’s proprietary Soft Clipping circuitry on all channels. Soft Clipping gently limits the output of the T 744 to minimize
audible distortion, even should the receiver be over-driven.
NOTE: Soft Clipping may simply be left on at all times to reduce the likelihood of audible distortion from excessive volume settings. However, for
critical listening, to preserve optimum dynamics you may wish to defeat it by setting this switch off.
6
7
IR: These mini-jacks accept and output remote-control codes in electrical format, using industry-standard protocols, for use with “IR-repeater” and
multi-room systems and related technologies. Consult your NAD audio specialist for more information.
+12V TRIGGER IN/OUT:
TRIGGER IN connects to the 12-volt trigger outputs of compatible components such as power controllers and home automation devices. The TRIGGER
AUTO/OFF switch selects the 12V Trigger Input and disables the remote and front panel ON function.
TRIGGER OUT connects to 12V Input of compatible devices (such as amplifiers and projector-lifts) to automate turn on/off or activation. See “Trigger
Setup”, your NAD audio specialist also can provide more information on using the T 744’s triggers.
AUTO TRIGGER SWITCH when in the AUTO position, forces the T 744 to turn on only when a trigger signal is present at the trigger input. When in
the OFF position, the trigger inputs are disabled.

COMPONENT VIDEO IN 1-2; OUT: Connect the COMPONENT VIDEO IN 1, and 2 inputs to component-video outputs from compatible source
components, typically a DVD player and terrestrial or satellite HDTV tuner. Connect the T 744 COMPONENT VIDEO OUT to the component-video
input of a compatible video monitor/TV. Be sure to observe consistency in connecting the Y/Cr/Cb jacks (some source and TV components label
these Y/ Pb/Pr) to the corresponding sources/inputs; do not rely purely on the colour-coding of the jacks, which may not always be consistent
among brands. The routing of the component-video inputs follows the S-Video/composite, but is default as: COMPONENT VIDEO IN 1 is routed
to the COMPONENT VIDEO OUT jacks when the DVD input is selected; COMPONENT VIDEO IN 2 is selected when the SAT input is active; the audio
and digital inputs assigned to DVD, and SAT will be used (see also, "Input Setup”).
NOTE: The T 744’s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 744 does not display its
on-screen menus on its component-video output. To use on-screen menus, you will need to make an S-Video or composite connection between
the T 744 and the monitor/TV, and select it for menu display.
9
AC POWER CORD: After you have completed all connections to the amplifier, plug the AC line cord into a “live” wall socket.
10 POWER: Press in to switch the A/V Receiver to standby mode. Pressing POWER again turns the unit OFF, recommended if you do not plan to use
your A/V Receiver for an extended period of time. It is usual (and perfectly acceptable) to leave the T 744 in Standby mode in between normal
viewing and listening sessions.
11 SWITCHED AC OUTLET: This convenience jack can supply switched power to another component or accessory. It is powered on and off by the
front panel STANDBY SWITCH (or the HTR2’s [On] and [Off] keys).
NOTE: The total draw of all devices connected to this jack must not exceed 120 watts.
12 SPEAKERS A & B: Connect the left and right front, centre, left and right surround, and surround back speaker outputs to the corresponding
loudspeakers. Each output’s “+” (red) terminal and “-“ (black) terminal must be connected to the corresponding “+” and “-“ terminals of the
loudspeaker. Use extra care to ensure that no stray wires or strands cross between posts or terminals at either end.
Connect Speakers B left and right speaker outputs to the corresponding remote loudspeakers. When speakers B are activated the output is taken
from the front left and right channels and any signal source is converted “downmixed” to stereo as indicated in the florescent display.
NOTE: Use stranded wire of at least 16 gauge (AWG); specialized speaker cable may be valuable (consult your NAD audio specialist). Connections
to the T 744 can be made with banana plugs (US model only), or using bare wire, or pins, by loosening the terminal’s plastic nut, making a clean,
neat connection, and re-tightening carefully (use the transverse hole through the post for bare-wire or pin connections). To minimize the danger
of short-circuits, ensure that only 1/2-inch of exposed wire or pin is employed in connecting.
NOTE: This unit is designed to produce optimum sound quality when connected to speakers with impedances within the receiver’s operating
range. Please check front, center, and surround speakers are rated to be 4Ω min. per speaker.
IMPORTANT NOTE: For optimum surround performance, the T 744 speaker settings and levels must be set correctly via the receiver’s setup
routines; see “Setting Up the T 744”.
13 DVD, SAT, VCR, VIDEO 4, VIDEO 5: These comprise the T 744’s principal inputs. Connect S-Video, composite video, and analog stereo audio from
source components such as DVD players and HDTV/satellite tuners (see "Input Setup," below). VCR and VIDEO 4 may be used with recording
components such as videocassette or DVD-recorders; connect the T 744 S-Video/composite video OUT jacks to these components’ record-inputs.
(Note that VCR/VIDEO 4 may freely be used for play-only components, in which case their OUT jacks would remain unconnected.)
14 MAIN IN/AUDIO PRE-OUTS/SUBWOOFER OUT: The T 744’s five built-in power amplifier channels will deliver excellent quality with even very
demanding, low sensitivity home-theatre speaker systems. However, it is also possible to use the T 744 as a pre-amplifier with external power
amplifiers for some of all channels (remove the supplied jumpers) if necessary. Unlike the six full range channels, there is no power amplifier built-
into the T 744 for a subwoofer.
Connect the SW output 1, 2 or both to powered (“active”) subwoofers (or to power amplifier channels driving a passive system).
SURR-BACK-R jack will supply the same signal from the surround-back Left channel if the T 744 is so configured (see “Speaker Setup,” below).
Either one or both channels are available mono or stereo as per “Speaker Setup”. Connect to one or two channels of an appropriate external
power amplifier or other amplified component to furnish amplification for one or two surround back speakers. Your NAD audio specialist will be
happy to advise you.
NOTE: Never connect the T 744’s speaker outputs and the speaker outputs of an external amplifier to the same speakers.
15 TAPE IN/OUT: Connect the T 744’s TAPE OUT jacks to the stereo analog audio inputs, of an audio recording component such as a cassette deck
or CD recorder, or of an outboard analog audio processor such as a stereo equalizer; connect the receiver’s TAPE IN jacks to the component’s
corresponding outputs.
NOTE: Digital input signals are not available at the analog TAPE OUT jacks.
16 DISC: Connect the analog stereo audio output from a second CD player or other line-level audio source to this input.
NOTE: Connecting a phonograph turntable to the T 744 requires an outboard magnetic phono-preamp component such as the NAD PP2; you
cannot connect turntable directly to the DISC inputs.
17 5.1 CH. INPUT: Connect to the corresponding analog audio outputs of a multichannel source component such as a DVD-Audio or multichannel-
SACD player, or external multichannel decoder. Typically, these sources will produce 5.1-channel output, in which case the SURROUND BACK jacks
are left unconnected. The signals present at these jacks may be heard by selecting the front-panel soure Down and Up key or the HTR 2’s [Ext
5.1] button. See “Selecting Sources," below.
NOTE: There is no bass-management or other processing (other than master-volume control) available to this 5.1 CH. INPUT. While the multi-
channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 744’s own Dolby Digital and DTS decoding and digital-
analog converters, via a digital connection, will usually produce superior results.

SETTING UP THE T 744
GETTING STARTED
Before you make the first connection to your T 744, you should have the arrangement of your listening room/
home theater components and furniture mapped out, at least initially. Unfortunately, a discussion of the vital
questions of loudspeaker placement and listening/viewing positions is beyond our scope here. Suffice it to
say that these two questions will influence your system's ultimate performance every bit as powerfully as
your selection of electronics and speakers. Your NAD audio specialist dealer will be happy to advise you, and
to recommend reference materials.
NOTE: You will need the HTR 2 remote handset to configure your T 744. See “Using the HTR 2 Remote”,
below.
DEALING WITH HUM AND NOISE
Hum and noise sometimes prove a challenge in complex, multichannel audio systems. Note these consider-
ations to help prevent hum and noise problems:
•
Power all your system's audio component from AC outlets originating from the same circuit of your house
wiring. As far as possible, power all audio components from the same outlet, or adjacent outlets on the
same circuit. It may be useful to power video displays (and computers!) from outlets on another circuit,
especially if that circuit is supplied from the other "leg" of the house wiring.
•
Do not bundle analog audio cables with AC power cables, or with coaxial digital-audio cables. It is best
if they cross at right angles if they must be in close proximity.
•
•
Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are secure.
A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, low-resistance
contact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging and re-plugging,
since the gold (or copper) contact plating of typical cable connectors, even very high-quality ones, is very
thin and easily worn.
Track down hum/noise problems one component at a time, working backwards from the receiver. That is:
Connect the speakers to the receiver only, and check for hum. Then connect one component only (a CD
player, for example) alone, with no other components connected and check for hum. Connect additional
components, one at a time, to the receiver and check for hum. At each stage, if hum/noise appears,
examine the audio cabling and AC-power routing of the new component. In some cases, moving the new
component's AC cord to a different outlet, or installing a ground-lift (3-to-2-prong adapter) on its power
cord, will eliminate the hum.

ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT
The T 744 receiver employs a simple, self-explanatory system of on-screen display "menus" that will appear
on the connected video monitor/TV. These are required during the setup process (and are useful in day-to-
day operation), so be sure to connect the monitor/TV before proceeding with setup.
NOTE: The on-screen displays are carried on both the S-Video and composite MONITOR OUT jacks, but are
not incorporated into the component-video output.
DISPLAY THE OSD
Press any of the HTR 2 remote's central cursor keys ([ꢀ], [ꢂ], [ꢁ], [ꢃ], and [Enter]) to display the T
744’s main <Setup> menu on your video monitor/TV. If the OSD does not appear, check your MONITOR OUT
connections.
NOTE: The OSD does not appear on the T 744's component-video output, nor does it appear on the VIDEO
3 and 4 record-outputs; these are for recording, not monitoring.
NAVIGATING THE OSD AND MAKING CHANGES
Use the HTR 2 remote's [ꢂ/ꢃ] keys to move up or down among the Setup menu's list of items; use [Enter]
to select a menu item, and use [ꢀ/ꢁ] to change the parameter-value (setting) of any item. Selecting the
<Save and Exit> returns "up" to the <Setup> menu while saving any parameter-value changes to the T 744’s
memory; selecting <Do Not Save and Exit> also returns to the main <Setup> menu, but abandons any
changes made on the previous menu. Selecting <Exit> from the main Setup menu exits the OSD altogether,
retaining parameter-value changes, if any, made previously.
INPUT SETUP
The T 744 is equipped with nine configurable and nameable inputs: six audio-video inputs labeled DVD, SAT,
VCR, and VIDEO 4-6 (including VIDEO 6 on the front panel), and two audio-only inputs labeled CD and EXT
7.1. These are flexibly configurable and nameable: For each labeled video input-jack position (DVD, SAT,
VCR, VIDEO 4-6) as displayed on the <Video In> line of the <Input Settings> menu, you may freely assign:
an analog audio input selected on the <Audio In> line; and a digital input selected on the <Digital In> line.
These will become active whenever that input is selected.
NOTE: An incoming digital signal present at the assigned digital input will always take precedence over the
assigned analog-audio input, even if both are present. The digital signal can be temporarily selected “OFF”
using the front panel DIGITAL AUDIO SELECTOR button.
INPUT SETTINGS
From the main <Setup> menu, select the <Input settings> menu item using the HTR 2 remote's [ꢂ/ꢃ], and
[Enter] keys. Using the [ꢀ/ꢁ] keys select the video input (DVD, SAT, VCR, VIDEO 1-6) you wish to
configure. Use the [ꢂ/ꢃ] keys to move to the <Audio In> line, and then use the [ꢀ/ꢁ] keys to select
the analog audio input you wish to be linked to that input (usually, this will be the same, i.e., “DVD” with
“DVD,” “Video 4” with “Video 4,” and so on).
NOTE: It is not necessary to have an analog audio input connected for every video input you employ. In fact,
in some cases—for example for a DVD player—it may be preferable to make only a coaxial or optical digital
audio link to the T 744 for audio playback. This avoids possible confusion, and ensures that the T 744’s high-
performance surround and digital audio circuitry will always be employed.
Now use the [ꢂ/ꢃ] keys to move to the <Digital In> line and select the digital input (“Opt 1-2,” “Coax 1-
4”) you wish linked to that input. If you set <Digital In> to “Off,” no incoming digital signal will be selected
by that input. (Set an input’s <Digital in> to “Off” only if you wish to ensure that that input will not play an
incoming digital bitstream, even if one is present.)
NOTE: The <Trigger Out:> line of the <Input Settings> menu is used to configure the T 744’s 12-volt trigger.
See “Trigger Setup”.
The component-video inputs are not configurable. Selecting the DVD input routes the COMPONENT VIDEO
IN 1 to the COMPONENT VIDEO OUT jacks; selecting SAT routes COMPONENT VIDEO IN 2 to the COMPO-
NENT VIDEO OUT jacks. Note that the OSD does not appear on the component-video output.
NOTE THAT: The combination of analog-audio input and digital input assigned above will always be recalled
whenever that input is selected via the front-panel VIDEO key, or the HTR 2 remote’s input-select keys, or
by recalling a Preset;
The digital and analog audio inputs assigned to a video input can be overridden by using the front-panel
AUDIO and DIGITAL AUDIO SELECTOR keys; however, the assigned input will return whenever that video
input is reselected, either via the front panel VIDEO key or using the HTR 2’s input-select keys (or a Preset);
Any audio input and any digital input may be configured with any video input, and the same analog and/or
digital inputs may be assigned to multiple video inputs;
The analog audio input selected on the <Audio In> line is also routed to the TAPE OUT jacks.
NOTE: That signals from digital inputs are not available on the analog TAPE OUT jacks.

ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT
SPEAKER SETUP
Every surround-sound system requires "bass-management" to direct low-frequency content from any or all
channels to the speakers best able to reproduce it. For this function to operate correctly, it is important that
you correctly identify your speakers' capabilities.
We use the terms "Small" and "Large" (and "Off"), but note that physical size may be irrelevant.
•
A "Small" speaker is any model, regardless of physical size, that lacks significant deep-bass response,
that is, below about 80 Hz.
•
•
A "Large" speaker is any full-range model, that is, one with deep-bass response
An "Off" speaker is one that is not present in your system. For example, you might not have any surround-
back speakers installed; in that case, you would set the <Surr Back> setup item to "OFF".
Depending on the relationship between speakers, the possible selections for each speaker are as follows:
Front L/R
Center
Surr. L/R
Subwoofer
LARGE
LARGE
SMALL
OFF
LARGE
ON
or

SPEAKER SETTINGS
From the OSD’s main <Setup> menu select the <Speaker Settings> line using the HTR 2 remote's [ꢂ/ꢃ],
and [Enter] keys. Using the [ꢀ/ꢁ] keys, set <Front:> to "Large" or "Small” as your main-front speakers
require according to the guidelines noted above. Similarly, set <Center:>, <Surround:>, and <Surr Back:> to
"Large," "Small," or "Off" as your system's loudspeakers require. Set <Sub:> to "On" or “Off,” selecting
“On” only if you have a subwoofer connected to the T 744's SUB analog output jack.
NOTE: The Speaker Settings configuration is “global”; that is, it remains in force with all inputs and in all
listening modes. However, speaker settings are part of the T 744’s Preset system; consequently, multiple
speaker settings can be stored for easy recall as different types of recordings or listening modes require.
See “Creating and Using Presets”.
NOTE: You can set Subwoofer to "On" even with "Large" front speakers, in which case bass content from
any channels set to "Small" will be routed to both the subwoofer and to the front speakers; LFE-channel
signal will pass only to the sub. In most subwoofer-equipped systems, setting front speakers to "Small" is
usually the better option.
LISTENING MODE
From the OSD’s main <Setup> menu select the <Listening Mode> line using the HTR 2 remote's [ꢂ/ꢃ], and
[Enter] keys. Using the [ꢂ/ꢃ] and [ꢀ/ꢁ] keys you can select mode variations, and adjust various
parameters, depending on the current Listening Mode. For more information, see “About the T 744's
Listening Modes”.
NOTE: Listening Mode is part of the T 744’s Preset system. See “Creating and Using Presets,” below;
NOTE: The Listening Mode used the last time a given input was selected will be recalled the next time that
input is selected, unless overridden by a Dolby Digital or DTS signal, which automatically invoke their native
Listening Modes.

CHANNEL-BALANCE (TEST) SETUP
Adjusting the relative balance of your system's loudspeakers ensures that surround-sound recordings,
whether music or film, will present the balance of effects, music, and dialog that the artists intended.
Additionally, if your system incorporates a subwoofer it establishes a correct relationship between the
volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic
elements.
USING AN SPL METER
It is quite practical to perform the T 744 Level setup routines "by ear," and careful work will produce
acceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter, such as
Radio Shack part number 33-2050, makes this task easier, more accurate and more repeatable. Ownership
of such a meter could prove a valuable audio tool; your NAD audio specialist may be able to help you with
temporary use of a meter.
The SPL meter should be placed at the primary listening position, at approximately the height of the seated
listener's head. A tripod is helpful, but with a little duct tape almost anything — a pole lamp, music-stand,
or ladder-backed chair, for example — can do as well. Just be sure that no large acoustically reflective
surfaces obstruct or are near the microphone element. Orient the meter with its microphone (usually at one
end) pointing straight up toward the ceiling (not forward toward the speakers) and ensure that its "C"
weighting scale is selected. Set the meter to display 75 dB SPL. (On Radio Shack meters this necessitates
either setting the meter to its 80 dB range and taking your readings at the -5 point, or selecting the 70 dB
range and reading at the +5 point.)
SETTING CHANNEL BALANCE
Press the HTR 2 remote’s [Test] key, activating the T 744’s channel-balancing test signal and displaying the
<Channel Levels> menu on the OSD. You will hear a "surf" sound that cycles through your speakers,
beginning with the left-front. (If you do not hear the test signal, check your speaker connections (above),
and your <Speaker settings> OSD menu settings, (above.)
As the test signal cycles around the speakers, the OSD (and the VFL front panel display) will highlight the
currently playing channel. Now use the remote's [ꢀ/ꢁ] keys to adjust the loudness of the noise output
from the currently playing channel to the required level (it’s usually simplest to begin with the left-front). The
"level offset" reading on the right will change by 1 dB increments; 12 dB adjustment is available.
NOTE: If you are balancing levels "by ear", choose one speaker—usually the center—as a reference and
adjust each of the others in turn to "sound as loud" as the reference. Be sure that you remain in the primary
listening position while balancing all channels.
Using the remote's [ꢂ/ꢃ] and [ꢀ/ꢁ] keys adjust each speaker to produce the same SPL meter reading
(or subjective loudness). Note that:
•
•
All speakers must be in their final locations before level-setting.
Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to its
highest-possible frequency if you are using the T 744's SUBWOOFER output. Final subwoofer-level
adjustment “by-ear,” using music and film sound material, is frequently useful.
•
Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always
calibrate to exactly the same level offset readings.
SPEAKER DISTANCE
Your system's speaker distance settings are a subtle but important refinement of your setup. Informing the
T 744 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct delays,
optimizing imaging, intelligibility, and surround-sound ambience. Enter your dimensions with precision within
about 1 foot (30 cm).
SETTING SPEAKER DISTANCE
From the OSD’s main <Setup> menu, select the <Speaker Distance> item using the remote's [ꢂ/ꢃ] and
[Enter] keys. Using the [ꢀ/ꢁ] keys, set <Front> and <Center:> to the distance measuring from your
principal listening position to the front surface of the front and center loudspeakers. Using the same remote
keys, set <Surround> to the distance of the nearest surround-channel speaker.
NOTE: Distance can be displayed as feet or meters selectable by the <DISTANCE> item in the Speaker
Distance menu.
ADVANCED OPTIONS
The T 744 allows for setting of special listening and system options. These are usually one-time options
settings and once set do not need to be changed.
BACKGROUND to “ON” or “OFF”
When “ON” is selected, on-screen menus will appear against a black background, obscuring the current
video program (if any), when “OFF” is selected menus will appear in white text superimposed upon the
current video program (if any).
TEMP OSD
TEMP OSD. When “ON” is selected, the temporary OSD such as volume, and speaker levels are displayed.
When “OFF” no temporary OSD will be displayed.

ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT
CREATING AND USING PRESETS
The T 744’s simple but powerfully flexible system of “Presets” allows you to customize virtually every aspect
of your audio-video playback, and recall them with a single key-press. Every parameter of T 744 operation
that is available from the main <Setup> menu — input settings, level settings, delay settings, speaker
settings, and listening mode selection and adjustments — is stored, together, as a single Preset. You might
create one Preset optimized for pop music and another for classical, or Presets that recall each family
member’s favorite setup, or one for fully cinematic home-theater playback and another for late-night
movies, with each Preset’s surround mode, channel levels, and speaker-setup fine-tuned to a particular
scenario or preference.
CREATING PRESETS
Creating a Preset consists simply of storing a complete set of all settings accessible from the main <Setup>
menu, including Tone Control settings. To save a collection of settings to a Preset, use the HTR 2 remote’s
[ꢂ/ꢃ] keys to scroll to the to main <Save to Preset> item. Use [ꢂ/ꢃ] to scroll to the desired Preset’s line
[1-5]; <Stored> will be flashing. Now press the HTR 2’s [Enter] to store the Preset; <Stored> will be stop
flashing, confirming that the Preset has been stored.
NOTE: The selected Preset remains in force until you select a different Preset.
NOTE: It is strongly recommended to leave Preset 1 “empty”; that is, memorized with no changes at all
made to the calibrated values you have entered on all of the <Setup> menu lines. This will make returning
to your calibrated setup defaults easy.
RECALLING PRESETS
You may recall a Preset at any time; the newly recalled Preset will replace the previous Preset (if any).
Presets can only be recalled using the HTR 2 remote:
Press the HTR 2’s square [A/V Preset] key (red dot), then press the numeric key 1-5 corresponding to the
desired preset.
NOTE: The [A/V Preset] key works as a momentary “shift” key: You must press it every time before invoking
a Preset via a numeric key.

USING THE T 744
You may operate the T 744 receiver from its front panel or via the HTR 2 remote control. Since the remote
will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure also to
read the section, "Front Panel" above.
SELECTING SOURCES
With the HTR 2’s remote's [Amp] device selected, the remote’s numeric-key section directly selects the
receiver’s inputs, plus the internal tuner ([Tuner), Tape Monitor ([Tape]), and multichannel input ([Ext. 7.1/
5.1]) refer to the red labels directly above each key.
•
When an audio-only source (CD, DISC, TUNER) is selected, the most recently-selected video signal
remains selected, until another audio-video input is selected
•
•
When you change sources, the VFL will display the new input in its primary display.
A newly selected input's listening mode (Stereo, EARS, Pro Logic II, etc.) will revert to the mode to which
it is configured on the <Input Settings> line of the setup menu, unless the incoming signal is a Dolby
Digital or DTS source, in which case the input will be set automatically to the appropriate decoding mode.
ADJUSTING THE VOLUME
Use the HTR 2 remote's <Volume up/down> keys to adjust the "master volume" of the T 744, raising or
lower all channels together. Note that:
•
•
A momentary keypress will change the master volume by 1 dB increments; if you hold down <Volume up/
down> the master-volume change will "run-on" until the key is released.
The T 744's OSD will show the volume setting as a line graphic with a numeric display above in dB relative
to the reference level.
Since recordings vary considerably in overall average level, there is no imperative to listen at any particular
master-volume setting. A setting of -20 may sound "as loud" from one CD or DVD as -10 does from another.
•
•
If muting has been activated (below), adjusting master-volume via the HTR 2 remote or the front-panel
knob automatically releases the mute function.
The T 744 will power-up from Standby mode at whatever master volume setting was last used; however,
if the prior setting was greater than –20 dB the T 744 will power up to –20 dB. This prevents inadvertently
beginning a session at excessive volume.
MUTING THE SOUND
Use the HTR 2 remote's <Mute> key to silence all channels completely. Muting is always available,
regardless of source or listening mode selections. Note that:
•
Cycling through Standby or powering off does release muting; the T 744 will return from Standby with
muting off if Standby was invoked with muting on.
•
•
Changing input or listening-mode selections does not release muting.
Adjusting the master-volume upward via the HTR 2 or the front-panel knob automatically releases the
mute function.
LISTENING TO RADIO
The T 744’s internal AM/FM tuner offers very high quality sound from radio broadcasts. Note that reception
and sound quality will always be dependent to a degree on the type of antenna(s) used, as well as proximity
to the broadcast origin, geography, and weather conditions.
ABOUT ANTENNAS
The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using the
‘balun’ included adapter, and should be fully extended to form a “T”. This folded-dipole antenna will usually
work best oriented vertically, with the arms of its “T” full outstretched and arranged perpendicular to the
origin of the desired broadcast. There are no ‘rules,’ however, and experimenting freely with antenna
placement and orientation may yield the clearest sound and lowest background noise. In areas of poor FM
reception, an exterior FM antenna can improve performance dramatically. If radio listening is important to
you, consider consulting an antenna installation professional to optimize your system.
The supplied AM ‘loop’ antenna will usually provide adequate reception. However, an exterior AM antenna
can be used to improve reception; consult an antenna professional for more information.

USING THE T 744
SELECTING THE RADIO
Press the AM/FM key on the T 744 front panel, the HTR 2’s orange [TUNER] (the numeric 9 key), or the
yellow [AM] and [FM] keys to select the receiver’s radio mode. Each subsequent press of either key will
toggle the unit between its FM and AM bands.
TUNING STATIONS
Press SEARCHꢀꢁon the front panel momentarily to step up or down between FM or AM frequencies.
Press and hold SEARCHꢀꢁfor more than 2 seconds to search up or down; the T 744’s tuner will stop at
the next sufficiently strong signal it encounters. See “Front Panel,” above. Pressing the SEARCHꢀꢁkeys
momentarily during the search process will stop the search.
After first pressing amber [TUNER] mode-select key on the HTR 2 to set the remote to control radio
functions, press [TUNE DOWN] or [TUNE UP] on the HTR 2 (yellow lettering); hold in to perform slow manual
search, press momentarily to automatically search (see above).
SETTING RADIO PRESETS
The T 744 can store as many as 40 of your favorite radio stations for immediate recall; 30 FM stations and
10 AM. To store a radio preset, first tune the desired frequency (see above), then press the front panel
MEMORY key. Press the PRESETꢀꢁkey to select the preset number to be assigned. Then press the
MEMORY key once again. The STORED message will appear in the VFL Display.
NOTE: The Radio Presets must be stored from the front panel; this setup function is not accessible from the
HTR 2 remote.
NOTE: The T 744’s Radio Presets are distinct from its “global” Presets that can be used to manage listening
and setup modes and levels. See “Using Presets,” above.
SELECTING RADIO PRESETS
Press PRESETꢀꢁon the front panel to step up or down between presets; press and hold PRESETꢀꢁto
“scroll” continuously up or down. The HTR 2 remote’s [PRESETꢂ/ꢃ] keys work similarly.
CHOOSING THE FM MUTE / MODE
The front-panel FM MUTE/Mode key is a dual-purpose control. First, it “toggles” the T 744 between stereo
mute and unmated stereo reception (assuming that a multiplex-stereo station of sufficient strength is
tuned). FM Mute eliminates noise from “empty” FM frequencies but also mutes very weak or distant
stations; it also causes the search function to skip them. Toggling off the FM Mute will result in reduced
noise if the FM station signal level is less than the FM Stereo threshold (since mono FM is inherently less
noise-prone), though at the sacrifice of the stereo effect.
NOTE: The one can store the same channel in two preset locations; one with FM Mute On, and with FM
Mute Off.
NOTE: Toggling between FM Mute on or off also defeats the T 744’s FM muting circuit. If you wish to listen
to a particularly weak or distant broadcast, toggle off the FM Mute and tune it manually.
ABOUT RDS
The Radio Data System (RDS) permits compatible FM receivers to display text determined by the broadcaster.
The T 744 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). However, not every
FM station incorporates RDS in its broadcast signal; in most areas you will find from one to several RDS-
enabled stations, but it is by no means impossible that your favorite stations will not be broadcasting RDS
data.
VIEW RDS TEXT
When an RDS-enabled FM broadcast is tuned, after a brief delay the “RDS” symbol will light in the T 744’s
front-panel readout and the readout’s character section will show its station-name (PS) text: “ROCK101,”
for example. Press the front-panel DISPLAY key to toggle the readout between this and the station’s radio-
text (RT) readout, if any, which might scroll song- or artist-name, or any other text of the station’s choosing.
ABOUT USER NAMES
You can assign an eight character “User Name” to each radio preset, which will show in the front-panel
readout whenever that preset is recalled.
ENTERING USER NAMES
For example, to name a radio preset “NEWS”: recall the desired radio preset, and then press the front-panel
MEMORY key once, then within five (5) seconds, press the front-panel DISPLAY key; the readout shows a
blinking box. Use the SEARCHꢀꢁkeys to select the first character of the name (“N” from the alphabetic
list; press either PRESETꢀꢁkey to select the character and move to the next position. Repeat this process
for each character in sequence; press the MEMORY key again to store the User Name and exit the text-entry
mode.

ABOUT DTS AND DOLBY DIGITAL SURROUND MODES
DTS DIGITAL SURROUND
The Digital Theater System Digital Surround (simply called DTS) is a multichannel digital signal format that
can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are 5.1 channel
media formats, discs bearing the “DTS” symbol are thought to provide better sound quality due to the lower
audio compression required.
It also offers a broader dynamic, producing magnificent sound quality.
“DTS” is a registered trademarks of Digital Theater Systems, Inc.
DOLBY DIGITAL
Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs bearing the
“DOLBY/Digital” symbol were recorded with up to 5.1 channels of digital signals, reproducing a much better
sound quality, with dynamic and spatial sound sensations that are much better than in the previous Dolby
Surround.
DOLBY PRO LOGIC
Dolby Pro Logic is a surround format consisting of four channels (front right, centre, front left and surround.
Media sources with the “Dolby Surround” feature produce a theatre–like surround sound. The surround
channel is monophonic, but it is reproduced in both surround speakers.
DOLBY PRO LOGIC II SURROUND
This mode applies conventional 2-channel signals such as digital PCM or analog stereo signals as well as
Dolby Surround signals, etc. to surround processing which offers improvements over conventional Dolby Pro
Logic circuits. Dolby Pro Logic II surround has two decoding modes:
DOLBY PRO LOGIC II MOVIE
Designed for the cinema, this method highlights the cinematic sound quality by adding a process that
emphasises the special effects of action scenes.
DOLBY PRO LOGIC II MUSIC
Designed for music, this method highlights the sound quality of music by adding a process that emphasises
the musical effects.
Manufactured under license from Dolby Laboratories.

ABOUT THE T 744'S LISTENING MODES
The T 744 receiver offers nine distinct listening modes, tailored for different types of recordings or program
material. The table below lists which modes are available to what input signals.
With a two-channel (STEREO) source the following listening modes can be selected:
•
•
Stereo
Downmix
All output is directed to the left/right-front channels; low frequencies are directed to the subwoofer if one
is present in the Speaker settings. Select Stereo when you wish to listen to a stereo (or monaural)
production, such as a music CD or FM broadcast, without surround enhancement. Stereo recordings,
whether in PCM/digital or analog form and whether surround-encoded or not encoded, are reproduced
as recorded; multichannel digital recordings (Dolby Digital and DTS) are reproduced in “Downmix” mode
via the left- and right-front channels only, as Lt/Rt (left/right-total) signals.
•
•
Dolby Pro Logic
Dolby Pro Logic II (PLII)
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro Logic, or
ProLogic II surround processing, yielding output to left-, center-, and right-front channels, and discrete
left/right surround channels (assuming these are present in the current <Speakers Setup>. PLII does not
employ the surround back speakers (if any).
NOTE: ProLogic II is a more recent evolution of the original Dolby ProLogic surround processing that yields
more stable imaging and full bandwidth sound to the rear channels in Movie mode, offering sound that
is more similar to Dolby Digital decoding.
The T 744 provides two PLII variations: MOVIE and MUSIC. See “Adjusting Listening Modes,” below.
•
EARS
Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD
surround processing with signals output to the left, center-, and right-front channels and discrete left/
right surround channels, plus subwoofer (assuming these are present in the current <Speakers Setup>);
EARS does not employ the surround back speakers (if any). EARS extracts the natural ambience present
in nearly all well-produced stereo recordings. It does not synthesize any ambience or other sonic elements
and thus remains truer to the sound of the original musical performance than most other music-surround
options.
Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly
natural and believable ambience from nearly all "natural-acoustic" stereo recordings; typically, these
include classical, jazz, and folk genres as well as numerous examples from others. It's virtues include a
realistic, stable "front-stage" sonic imaging and spacious but unexaggerated ambient "virtual acoustics"
that remain faithful to the original recording.
•
•
Enhanced-Stereo 1 (ST1)
All recordings reproduced in stereo via the maximum speaker complement configured in the current
<Speakers Setup>. ST1 can be useful for maximum volume from all channels, or for multi-speaker
background music (cocktail party) listening.
Enhanced-Stereo 2 (ST2)
All recordings reproduced in stereo via the surround speakers only (plus subwoofer, if any), assuming
these are configured in the current <Speakers Setup>. ST2 can prove useful in certain late-night or very
low-volume listening situations.

USING THE T 744
The following Surround Sound Modes require a specially encoded signal that must be present in digital
format to be decoded by the T 744. These modes are automatically switched on when the appropriate data
stream is detected selected in the setup menu of the source media.
•
•
Dolby Digital
DTS
Digital recordings in Dolby Digital or DTS formats are reproduced via the channels employed in the original
recording (up to the maximum channels present in the current <Speaker Settings> setup).
NOTE: The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output. Your DVD
player probably includes its own setup menu that (among other things) lets you select the default bit-
stream format, and usually includes an “Auto” setting that directs the player to choose the Dolby Digital/
DTS signal whenever these are available. In a few cases, you may have to set the player’s bit-stream
manually to “DD/DTS” or an equivalent. In the case of DVDs that carry both Dolby Digital and DTS, you
will select one or the other from the disc’s (not the player’s) main menu.
Note also that while most Dolby Digital recordings are 5.1-channel surround productions, older examples
may be multichannel, 2-channel, or even monaural; the T 744 will automatically reproduce the Dolby
Digital signal with the maximum number of channels available.
The table below indicates which listening modes are available with the two types of audio signal sources:
digital- or analog-input 2-channel (whether the actual signal is monaural, stereo or surround-encoded), and
digital-multichannel (Dolby Digital or DTS). Where a listening mode is not available to a given signal source,
it will not appear in the <Listening Mode> selection rotation.

DISPLAYING THE SIGNAL MODE
Keying the front panel’s DISPLAY or HTR 2 remote's [DISP] key will display on the VFL the channel-mode of
the currently selected input signal, in the format “front/surround.subwoofer” (see “5 DISPLAY” in the
“Front Panel” section).
The following table shows examples of displays seen with various signal types:

etc.
SELECTING LISTENING MODES
Keying the HTR 2 remote's [SURR MODE] button steps through each of the T 744’s Listening Modes available
to the current input signal. It also momentarily displays the Listening Mode in the OSD.
NOTE: Changing the type of input signal may automatically change the Listening Mode: If the new signal
is a Dolby Digital or DTS recording, it will automatically invoke its native mode. The reverse is also true
if Dolby Digital or DTS was previously selected.

USING THE T 744
ADJUSTING LISTENING MODES
Several of the T 744’s listening modes have one or more selectable variations and adjustable parameters you
can modify to suit you system, the recording, or your personal preferences.
Use the HTR 2 remote's [Surr. Mode] key, or the front panel SURROUND MODE key, to select the Listening
Mode you wish to display and listen to; this will display on the T 744’s VFL Display. One can also select
variations using the HTR 2 [ꢀ/ꢁ] cursor keys on the <MODE:> line of the OSD. Use the HTR 2’s [ꢂ/ꢃ]
and [ꢀ/ꢁ] cursor keys to navigate among and modify that mode’s adjustable parameters (if any).
NOTE: Listening Mode parameter changes are maintained when you change listening modes. You may
also save a modified Listening Mode for easy recall by saving it to a Preset (see “Using Presets”).
Dolby Pro Logic II (PLII)
PLII MOVIE is optimized for film soundtracks.
PLII MUSIC for music recordings.
DIMENSION (-3 to +3): Adjusts front-rear emphasis of the surround effect independently from the relative
channel levels.
CENTER WIDTH (0 to 7): Modifies the “hard-centeredness” of the center image, by gradually mixing
mono-center content to the front-left/right speakers as well; a setting of 0 retains the center-channel-
only default, while a setting of 7 yields a fully phantom center channel.
PANORAMA (ON/OFF): Adds a “wraparound” effect by extending some stereo content into the surround
channels.
Downmix
Dolby Digital
Enhanced-Stereo 1 (ST1)
Enhanced-Stereo 2 (ST2)
DYN. RANGE (25, 50, 75, 100PCT): You can select the effective dynamic range (subjective range from soft
to loud) for playback of Dolby Digital soundtracks. For fully cinematic effect, always select 100PCT, the
default. Settings of 75, 50, and 25PCT progressively reduce dynamic range, making soft sounds compara-
tively louder while limiting the peak loudness of loud ones; the 25PCT setting will yield the least dynamic
range and is best for late-night sessions or other times when you wish to retain maximum dialog
intelligibility while minimizing overall volume levels.

Finally, make sure all the speaker terminals are tightened particularly if using banana plugs.
ADJUSTING CHANNEL LEVELS “ON THE FLY”
You can make changes to the relative levels of center, surround, and subwoofer outputs. This may prove
useful in a number of circumstances; for example, to increase (or tone down) a film's dialog level by raising
(lowering) the center channel, or to reduce excessive deep bass (or enhance deep bass) by lowering
(raising) the subwoofer level without having to go into the CHANNEL LEVELS OSD menu.
TO ADJUST CHANNEL LEVELS
Use the HTR 2 remote's [Surr.], [Center], and [Sub] [ꢂ/ꢃ] keys for direct-access level adjustment of these
channels, over a range of 12 dB. You can also adjust all channel levels using the front panel’s Levels key
(see “Front Panel,” above), or via the <Channel Levels> line of the main <Setup> menu.
NOTE THAT: The surround back channels (if any) adjust in lockstep with the surround channels;
Channel Level changes made via the HTR 2 are retained even if you cycle the receiver through Standby.
Channel Levels are part of the T 744’s Preset system. See “Creating and Using Presets”.
Level settings are added/subtracted to the setup levels established by the T 744 level-calibration routine,
invoked by the HTR 2 [Test] key. However, selecting any Preset will revert channel levels to those stored
in the preset.
ADJUSTING THE TONE CONTROLS
The T 744 bass and treble controls are adjusted using the front panel’s TONE CONTROLS (and TONE DEFEAT)
buttons; see “Front Panel”.
NOTE: Bass/treble settings affect only the front left/right channels, and are active in all listening modes.
Bass/treble settings are part of a Preset: Bass/treble settings in effect when a Preset is stored will be
reinstated whenever that Preset is recalled.

Controls up to 8 devices.
44 function keys.
Learns up to 352 commands.
Records up to 44 macros with a maximum of 64 commands each.
Configurable punch-through.
Key illumination with programmable timeout.
Upgradable.
Contains pre-programmed library of NAD remote codes.
The NAD HTR 2 is ready to operate the T 744 receiver right out of the box, but it is really eight remotes in
one. Each of the 8 Device Selector keys at the top of the handset can call up a new “page” of remote-
control codes to be transmitted by the remaining 44 keys. You may “teach” codes from any infrared-remote-
controlled component, regardless of brand, to any or all of these. Obviously, the most logical system is that
you teach the codes from your DVD player to the [DVD] Device Selector “page,” your television’s codes to
the [TV] “page,” and so on, but there is no required scheme: You may load any commands to any key on
any page (see “Learning Codes From Other Remotes,” below).
The HTR 2 is already preprogrammed with a full complement of commands for the T 744 receiver on its
[AMP] Device Selector page, and as well as with library commands to operate most NAD-brand DVD, CD, or
TAPE components on the corresponding Device Selector “pages.” These default commands are permanent:
Even if you teach the HTR 2 new commands to take their place, the underlying library commands remain in
place and can easily be recalled should you add an NAD component to your system later (see “Delete
Mode”, below).
NOTE: For use with the T 744, it should not be necessary to re-program any keys on the HTR 2 [AMP]
page. However, in order for the HTR 2 to control your specific NAD-brand components you may need to
load one or more different code-libraries; see “Loading Code Libraries,” below.
CONTROLLING THE T 744
The HTR 2 is divided into two main sections. Eight Device Selector keys at the top—[AMP], [DVD,] [TV,] and
so on—set the handset’s remaining keys to a “page” of commands to control a particular component. A
Device Select key determines only what component the HTR 2 will command; it does not perform any
function on the receiver. All of the remaining keys are function keys that can “learn” control codes from
virtually any infrared remote controller, allowing you to teach the codes of your equipment, regardless of
brand, to the HTR 2.
However, the HTR 2 is already preprogrammed to operate the T 744. All of the function keys on the [AMP]
Device Selector “page” perform T 744 functions. (The HTR 2 can also command many other NAD compo-
nents, from its [DVD,] [CD,] [TUNER,] and [TAPE] pages.)
It is important to note that certain HTR 2 keys perform different functions depending on the selected Device
Selector “page.” The color of the Device Selector key-labeling corresponds to the labeling of the function
keys. Most centrally, the red [AMP] Device Selector “page” corresponds to the red input-select labeling
adjacent to the numeric keys: When the HTR 2’s [AMP] Device Selector page is active, these keys select the
receiver inputs. Similarly, the purple [DVD] Device Selector “page” corresponds to several purple labels, the
green [TV] page to green labels, and so on.
LEARNING CODES FROM OTHER REMOTES
Begin by positioning the HTR 2 “nose-to-nose” with the source remote so the two devices’ infrared windows
are about 2 inches apart.

Enter Learning Mode: On the HTR 2, simultaneously press-and-hold for 3 seconds both a Device Selector
key and the [•] “record” key (just below the [DISP] key), until the Learn LED at the center of the HTR 2
turns steady green.
•
•
Press the HTR 2’s function key you wish to teach a command; the Learn LED will turn amber.
Press-and-hold the function key on the source remote: The HTR 2’s Learn LED will flicker amber for a
second or two, then turn solid green. The command is learned.
•
Press the HTR 2’s Device Selector key again to exit the learning mode.
If the Learn LED does not flicker amber you may need to vary the distance between the remotes.
If the Learn LED turns red rather than green, that particular command of that source remote command
could not be learned.
Cancel Operation:
You can cancel configuring a key, by pressing the active Device Selector key before the learn is complete;
the Learn LED will turn red.
Example: Learning “DVD Pause”:
Position the HTR 2 and your DVD player’s remote as described above.

USING THE HTR 2 REMOTE CONTROL
PUNCH-THROUGH
The HTR 2’s “punch-through” function allows you to retain a function key from one Device Select “page”
on another, so that, for example, the AMP [SURR MODE] function might still control the T 744 when the DVD
Device Selector page is active
NOTE: The HTR 2’s [VOL] keys are pre-programmed as “punched-through” for all Device Select pages:
[VOL] will operate the T 744’s master-volume regardless of the currently selected device. The [SURR.]
[CENTER,] and [SUB] Channel Volume controls similarly are pre-programmed as punched-through.
To set a punch through, after entering the Learning Mode, and pressing the desired key to be punched-
through, simply press the device key twice of the device to punch through to. The status LED will turn green;
press the Device Selector key again to exit Learning Mode.
Example: Punch-through the from the DVD “page” to the AMP [SURR MODE] key:
• On the HTR 2, simultaneously press-and-hold [DVD] and [•] (record); the Learn LED turns steady green.
• Press [SURR MODE]; the Learn LED turns amber.
• Press [AMP] twice; the Learn LED turns green.
• Press [DVD] again to exit the learning mode.
COPY A COMMAND FROM ANOTHER KEY
You may copy a command from any HTR 2 key to any other. To copy a key function, after entering the
Learning Mode, and pressing the desired key to be copied to, simply press the device key from which you
wish to copy, having first pressed its Device Selector key if it resides on another “page.” The status LED will
turn green; press the Device Selector key again to exit Learning Mode.
||
Example: Copy the Pause command from the CD page to the AMP [ ] key:
• On the HTR 2, simultaneously press-and-hold [AMP] and [•] (record); the Learn LED turns steady green.
||
• Press [
] (pause); the Learn LED turns amber.
||
• Press [CD]; press [
] (pause); the Learn LED turns green.
• Press [AMP] again to exit the learning mode.
NOTE: The copy and punch-through functions are similar. However, if you copy a command and then
subsequently delete, or over-write the original (source-key) command , the copied-to key’s command
remains unchanged. If you punch-through to a command and then delete or over-write the original key,
the punched-through functions also change accordingly.
MACRO COMMANDS
A “macro” command is a series of two or more remote codes issued automatically from a single keypress.
You might use a macro to automate a simple command sequence, such as, “Turn on the DVD player and then
press ‘play.’” Or you might compose an elaborate macro to power up an entire system, select a source,
choose a Listening Mode, and begin playback—again, all from a single keypress. The HTR 2 can store one
macro on each of its function keys (these exclude the Device Selector keys).
NOTE: Macros are independent of the currently selected device.
RECORDING MACROS
To record a macro, simultaneously press-and-hold for 3 seconds both the [MACRO] key and the HTR 2
function key to which you wish to assign the macro, until the status LED turns green. The macro button will
also light up. Press the sequence of function keys to be recorded into the macro, being sure to first press
the requisite Device Selector key for each function (you may switch devices while recording the macro as
many times as necessary), allowing you to create macro containing commands from more than one Device
Selector “page.” When you have finished entering the desired command sequence, press [MACRO] again
to store the macro; the Learn LED and [MACRO] key illumination will turn off.
NOTE: Each macro can store a maximum of 64 command steps. If you exceed this number, the macro will
be stored automatically after the 64th command is added.
Example: Record a Macro to the [0] key to Turn on the T 744, Select the DVD Input, and Commence
Playback:
•
•
•
On the HTR 2, simultaneously press-and-hold [MACRO] and [0] (numeric zero); the Learn LED turns
steady green.
Press [AMP]; press [ON]; press [1] (red “DVD”); press [DVD]; press [play] (the Learn LED blinks as
each step is added).
Press [MACRO] again to exit the macro-record mode.
To clear a macro, perform the above steps without entering any functions.
EXECUTING MACROS
To execute a macro, press and release [MACRO]; its key illumination lights for 5 seconds. While it remains
lit, press an HTR 2 key to which a macro has previously been stored. The corresponding macro will run; as
each step executes, its “parent” Device Selector’s key flashes lights briefly; when execution is finished, the
[MACRO] key illumination goes out. Pressing any other HTR 2 key while a macro is executing will abort the
macro. Remember that you must hold the HTR 2 so that its infrared emitter can activate the target
components.
NOTE: When a macro executes, a 1 second delay is automatically inserted between its commands. If you
need more than a 1 second delay between particular commands—for example, to permit a component to
power up completely—you can record “empty” steps into the macro by changing Device Selector “pages”
without entering actual command functions.

USING THE HTR 2 REMOTE CONTROL
KEY-ILLUMINATION TIMEOUT
The HTR 2’s key-illumination can be set to remain lit for 0-9 seconds. The default value is 2 seconds.
To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR 2’s [DISP] and the
[0-9] key, with the digit corresponding to the desired timeout duration; the Learn LED will flash twice to
confirm the new setting. When set to zero, the illumination will not turn on at all.
NOTE: Key illumination is the biggest drain on the HTR-2’s batteries. A short key-illumination timeout will
extend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still further.
FACTORY RESET
The HTR-2 can be reset to its factory state, deleting all learned commands, copied and punched-through
keys, macros, and other setup information, reverting all keys to their pre-programmed library commands. To
perform a factory reset simultaneously press-and-hold for 10 seconds the HTR 2’s [ON] and [RTN] keys; the
Learn LED will start to flash green. Release [ON] and [RTN] before the second flash is complete; the Learn
LED will turn red, indicate the remote has been reset.
NOTE: You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will not
reset; should this occur, repeat the full procedure.
DELETE MODE
The HTR 2 can store learned, copied, and “default library” commands on any single key. (The default library
commands are the pre-programmed NAD codes, such as the native T 744 commands on the [AMP] “page.”)
You can delete commands by layers back “down” to the default library command on any key, removing
learned commands, punched-through functions, and copied keys.
NOTE: The default library commands cannot be deleted, so you need not worry that using Delete Mode
might cause irreparable changes.
To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired key’s Device Selector
key and the [RTN] key, until the Learn LED turns green. Press the function key whose command you wish
to delete; the Learn LED flashes; the number of times indicates which type of function has become active—
see the table below. Press the active Device Selector key again to exit Delete Mode.
NOTE: You may delete multiple function-key commands on the same Device Selector “page,” but to
delete from more than one Device Selector page you must exit Delete Mode and then re-enter it on the
required page.

LOADING CODE-LIBRARIES
The HTR 2 can store a different library of default NAD codes for each of its Device Selector “pages.” If the
original default library does not control your NAD CD player, tape deck, DVD player, or other component,
follow the procedure below to change the code-library.
Begin by ensuring that the component you wish the HTR 2 to control is plugged in and powered-up (“on,”
not merely in standby). To enter the HTR 2’s Library Mode, simultaneously press-and-hold for 3 seconds both
the desired Device Selector key and the [A/V PRESET] key, until the Learn LED turns green. While keeping
the HTR 2 pointed toward the component, enter the first appropriate three-digit code-library number from
the table below. If the component turns off, press [ENTER] to accept that code-library number and exit the
Library Mode. If the component does not turn off, enter the next three-digit code-library number from the
table. When you enter the correct number the component will turn off; press [ENTER] to accept that code-
library number and exit the Library Mode.

USING THE HTR 2 REMOTE CONTROL
Search Mode
If none of the codes from the table, when entered, turns on the component, and if you are quite sure you
have followed the above procedure completely and carefully, you may want to try the “search” method as
follows:
Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired Device Selector
key and the [A/V PRESET] key, until the Learn LED turns green. Now press-and-hold the HTR 2’s [ꢂ] (or
[ꢃ]) key; the remote will step through all the available codes at a rate of approximately 1 per second. When
the component turns off, immediately release the cursor key; press [ENTER] to accept that code-library and
exit the Library Mode. Try a few commands; should you prove to have stepped past the needed code-library,
re-enter the Library Mode and use the cursor key to step back to it.
NOTE: It is possible that search mode will find code-libraries that operate, at least partially, some other-
brand (non-NAD) components. You may certainly exploit such capabilities as you find them. However,
since we can only ensure the completeness or accuracy of NAD code-libraries, we cannot support the HTR
2’s operation with other-brand components.
Checking Code-Library Number
You can check the current code-library on any Device Selector key as follows. Enter Library Mode by
simultaneously pressing-and-holding for 3 seconds both the desired component’s Device Selector key and
the [A/V PRESET] key, until the Learn LED turns green. Press the [DISP] key; the HTR 2 indicates the current
code-library by flashing its [TAPE], [VCR], and [MACRO] keys. For example, to indicate code-library #501 the
HTR 2 will flash [TAPE] 5 times, pause, and then flash [MACRO] once. You might wish to make a note of your
components’ code-library numbers.
