THANK YOU FOR CHOOSING NAD
The L70 A/V Surround Sound DVD Receiver is a technologically advanced and highly capable product-yet we have invested great effort in making it
simple and easy to use. The L70 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-theatre
components. As with all our products, NAD’s “Music First” design philosophy guided the L70’s design, such that it can confidently promise you both
state-of-the-art surround home-theatre 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 L70, and get the most from this
powerful and flexible home-theatre component.
One more thing: We urge you to register your L70 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 L70 receiver you will find:
An AM loop antenna
An FM ribbon-wire antenna with balun
•
•
•
•
The HTR L70 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 L70 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
L70 generates a modest amount of heat, but nothing that should trouble adjacent components. It is
perfectly possible to stack the L70 atop other components, but the reverse usually should be avoided.
Nonetheless, it is generally preferable that the L70 stands alone. It is especially important that sufficient
ventilation be provided; if you are contemplating locating the L70 within a cabinet or other furniture,
consult your NAD audio/video specialist for advice on providing adequate airflow.
ABOUT THE L70
Though the L70 is among the most technically sophisticated integrated A/V & DVD receivers, we worked
hard to make it one of the most musically transparent home-theatre components available as well; this is
what we mean by NAD’s “Music First” design philosophy. Here are just a few examples:
•
•
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.
The L70 incorporates a high quality DVD player with exceptional playability. The player has support
for DVD video and audio, VCD, SVCD with playback control (PBC), CD audio such as CD-RW as
well as MP3. As with all NAD DVD players, a set of convenient navigation buttons is provided on
the front panel. See “Front Panel Controls”.
•
Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.
E.A.R.S. AND DIGITAL SURROUND
A key element of the L70’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
L70’s substantial DSP power to route the ambient content that is “encrypted” in virtually all natural-
acoustic recordings to the appropriate main, centre 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, Movie and Emulation modes can also create enjoyable experiences from
2-channel sources.
On the digital side, the L70 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 synchronises 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, and 5.1-channel reproduction, with genuinely
superior sound quality in all modes.

Introduction
GETTING THE MOST FROM THE NAD L70
EASE OF USE
Despite the effort NAD has invested in the L70 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 L70 universal remote control is equally understandable, as are the L70’s own front-panel and on-
screen displays (OSD).
UPGRADABILITY
The L70 receiver permits flexible system growth via individually accessible 5.1 channel input for
connectivity to products with integrated surround decoders.
See “Rear Panel (5.1 CH. INPUT)”.
ABOUT THE HTR L70 SYSTEM REMOTE CONTROL
Packed with your L70 is the NAD HTR L70 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 L70 Remote Control,” to familiarize
yourself with the remote’s layout and operations before proceeding to setup your receiver.
Chances are, you will want to use your HTR L70 as your primary way to command your entire A/V system.
The HTR L70 can be employed to operate additional NAD or other-brand components such as a second
DVD/CD player, television, satellite/HDTV tuner, VCR, or virtually anything else that operates via standard
infrared remote control.
QUICKSTART
In case you simply cannot wait to experience the performance of your new NAD L70 DVD/Receiver, we
provide the following “Quickstart” instructions to get you underway. The steps below connect your L70
to a TV/monitor; be sure to read “Input Setup”.
PLAY A DVD MOVIE
•
•
•
Connect the L70’s composite video or S-Video “MONITOR OUT” jack to your TV/monitor’s
corresponding input.
Depending on the selection above, switch the “OSD SELECTOR” switch to either S-Video or
Composite position (found on the back of the L70 beside the Composite Output “MONITOR” jack.
Connect your left and right front speakers to the L70’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 centre and surround speakers as well, if you like). If your system includes
a powered subwoofer, connect the L70’s “SUBWOOFER PRE-OUT” jack to its line input.
Plug the AC mains plug into the AC; the LED on the front panel will be lit blue indicating the L70 is in
standby mode ready to accept commands from either the front panel power switch or the HTR L70 remote.
To start playback of the DVD player; press the HTR L70 remote’s “DVD” Device Selector key, and then
•
•
its transport key “Open/Close” to select the DVD, insert the media and press the transport
play
key to start playing. 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 either the L70’s Receiver or DVD
on-screen menu systems to check assignment of audio and video inputs; see “Input Setup”.)
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 L70 carefully and completely.

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 POWER key (or the HTR L70’s ON and OFF keys).
6
FM ANTENNA: The supplied wire “dipole” FM antenna will connect
to the FM connector using the supplied “balun” adaptor. 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.
NOTE
The total draw of all devices connected to this jack must not exceed
100 watts.

AC POWER CORD: Connect AC power cord to the Voltage
according to the model, 120 V for US and 240 V for Euro models.
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.
7
AM ANTENNA: The AM loop antenna supplied with the L70 (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.

OSD SELECTOR: This switch places the OSD (On Screen Display) to
either the Composite or S-Video MONITOR OUT.
COMPONENT VIDEO OUT (NTSC only): Connect the L70
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 input
is fixed: COMPONENT VIDEO OUT jack will only display the internal
DVD video signals.
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.
NOTE
The L70’s component-video output is a fully wide-band output,
compatible with all HDTV formats. The L70 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 L70 and the monitor/TV, and select it for menu display.

right surround 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.
NOTE
The L70 does not display its on-screen menus on its SCART/RGB
output. To use on-screen menus, you will need to make an S-Video
or composite connection between the L70 and the monitor/TV, and
select it for menu display. Refer to OSD SELECTOR.
NOTE
•
Use stranded wire of at least 16-gauge (AWG); specialized speaker
cable may be valuable (consult your NAD audio specialist).
Connections to the L70 can be made with banana-type plugs, 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.
9
OPTICAL OUT: Connect the OUT OPTICAL port to the
corresponding S/PDIF digital input of a recording component such as
a CD recorder, DAT deck, or computer soundcard. See “Setup.”
10 OPTICAL & COAXIAL IN: Connect to the coaxial/optical S/PDIF-
format digital output of sources such as VCRs, HDTV or satellite
tuners, or other components; connect IN OPTICAL/COAXIAL to an
S/PDIF-format digital output.
•
This unit is designed to produce optimum sound quality when
connected to speakers with impedances within the receiver’s
operating range. Please check front, centre, and surround speakers
are rated to be 8 Ohms min. per speaker.
11 12 V TRIGGER OUT: This mini-jack will control on or off any auxiliary
equipment with a 12V trigger input when the L70 switches from
standby to on state respectively. The maximum current this output
can handle is 50 mA at 12 V. Consult your NAD audio specialist for
more information.
IMPORTANT NOTE
For optimum surround performance, the L70 SPEAKER
CONFIGURATION and levels must be set correctly via the receiver’s
setup routines; see “SPEAKER CONFIGURATION.”
12 PRE-OUT SUBWOOFER: Connect this output to a powered
(“active”) subwoofer (or to a power amplifier channel driving a
passive system).
13 5.1 CHANNEL 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.
NOTE
There is no bass-management or other processing (other than
master-volume control) available to this 5.1 CHANNEL INPUT. While
the multi-channel audio outputs of a DVD-Video player can be
connected to these jacks, using the L70’s own Dolby Digital and DTS
decoding and digital-analog converters, via a digital connection, can
usually produce superior results.
14 CABLE/SAT & VCR: These comprise the L70’s principal inputs.
Connect S-Video, composite video, and analog stereo audio from
source components such as HDTV/satellite tuners (see “Setup”). VCR
may be used with recording components such as videocassette or
DVD-recorders; connect the L70 S-Video/composite video OUT jacks
to these components’ record-input. (Note that VCR may freely be
used for play-only components, in which case their IN jacks would
remain unconnected.)
NOTE
For best results when recording to a VCR, select “SURROUND:
STEREO”, and SUB: OFF in the receiver’s setup OSD.

Setup
SETTING UP THE L70
GETTING STARTED
Before you make the first connection to your L70, you should have the arrangement of your listening
room/home theatre 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
It is not absolutely necessary but one may find it easier to use the HTR L70 remote handset in conjunction
with the front panel buttons to configure your L70. See “Using the HTR L70 Remote”.
DEALING WITH HUM AND NOISE
Hum and noise sometimes prove a challenge in complex, multichannel audio systems. Note these
considerations to help prevent hum and noise problems:
•
Power your system’s entire audio components 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
VCR, 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 adaptor) on its power
cord, will eliminate the hum.
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT
The L70 receiver employs two; self-explanatory systems of on-screen display “menus” one for the L70
receiver, the other for the internal DVD player. These “menus” will appear on the connected video
monitor/TV and are required during the setup process (useful in day-to-day operation); so be sure to
connect the monitor/TV before proceeding with setup.
NOTE
The receiver’s on-screen displays (OSD) are carried to either one of the S-Video or composite MONITOR
OUT jacks as defined by the receivers OSD SELECT switch. In addition to the receiver’s OSD, there is
an internal DVD’s OSD; designed for greater enjoyment and flexibility when watching DVD/CDs by
allowing simultaneous output of the OSD on S-VIDEO, COMPOSITE, COMPONENT (NTSC models) and
SCART/RGB (PAL models).

Setup
SETTING UP THE L70
DISPLAYING THE L70 RECEIVER’S OSD
While in DVD mode, press the L70’s “SETUP” key momentarily for the DVD’s OSD, and for 3 seconds for
the receiver’s OSD. With the use of the navigation keys either on the L70’s front panel or the HTR L70
remote, you may select various menus. For the L70’s receiver, the <MAIN MENU> will display on your
video monitor/TV. If the OSD does not appear, check your MONITOR OUT connections either COMPOSITE
or S-VIDEO outputs, in conjunction with position of the OSD SELECT switch. Use the OSD Select switch
located on the back of the L70 beside the MONITOR OUT jacks to switch the OSD between COMPONENT
and S-VIDEO.
NOTE
The receiver’s OSD does not appear on the L70’s component-video (NTSC) or SCART/RGB (PAL) output,
nor does it appear on the VCR record-outputs; these are for recording, not monitoring during receiver
operation.
NAVIGATING THE OSD AND MAKING CHANGES
Press the SETUP button on the front panel of the L70 as described above in “Displaying the L70 Receiver’s
OSD”. Use the
keys of the HTR L70 or on the front panel, to move up or down among the Setup
to change the parameter-value
menu’s list of items; use “Enter” to select a menu item, and use
(setting) of any item. Selecting <MAIN MENU OFF> from the main setup menu exits the OSD altogether,
retaining parameter-value changes, if any, made previously.
When in the DVD OSD, pressing the “SETUP” button on the L70 will toggle off the dedicated DVD OSD
and at that moment the DVD settings will be stored.
NOTE
When playing any DVD, VCD, or CD the L70’s DVD OSD can be activated at any time. This convenient
feature allows one to change audio and video settings “on-the-fly” without the need to stop or pause
the media.
SETTING L70 OSD LANGUAGE (RECEIVER SECTION ONLY)
From the OSD’s <MAIN MENU> screen, select the <LANGUAGE> item using the remote's
and
“Enter” keys. Using the
keys, select between English, French or German for the L70’s receiver OSD.
INPUT SETUP
The L70 is equipped with four configurable inputs; 3 audio-video inputs labelled CAB/SAT, VCR, and
VIDEO 4 (VIDEO 4 on the front panel), and one set of audio-only labelled 5.1 CHANNEL INPUT. These will
become active whenever that input is selected.
NOTE
Incoming digital and audio signals present at either digital (either coaxial or optical) or analog inputs
are mutually exclusive. Any audio signal can be permanently selected toggling the L70’s “DISPLAY”
button through the choices shown either in the L70’s fluorescent display and OSD.

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 CAB/SAT-it may be preferable to make only a coaxial or optical digital
audio link to the L70 for audio playback. This avoids possible confusion, and ensures that the L70’s
high-performance surround and digital audio circuitry will always be employed.

Setup
SPEAKER CONFIGURATION
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”, “LARGE”, “NONE”, (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
A “NONE” 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:> setup item to “NONE.”
A “OFF” speaker is one that may be present such as a subwoofer but set to off for in the SPEAKER
CONFIGURATION setup menu such as <SUB: OFF>.
•
SETTING SPEAKER CONFIGURATION
From the OSD’s <MAIN MENU> screen, select the <SPEAKER CONFIGURATION> line using the HTR L70
remote’s
, 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>, and
<SURR> to “LARGE,” “SMALL,” or “NONE” as your system’s loudspeakers require. Set <SUB> to “ON”
or “OFF.”
NOTE
•
The SPEAKER CONFIGURATION is “global”; that is, it remains in force with all inputs and in all
SURROUND MODEs.
•
You can set Subwoofer to “ON” even with “LARGE” front speakers. In such cases, both subwoofer
and front speaker will receive the LFE-channel signal. In the case where the front speakers are set to
“SMALL” the LFE-channel signal will be routed to subwoofer but not to the front speakers; LFE-
channel signal will pass only to the subwoofer. In most subwoofer-equipped systems, setting front
speakers to “SMALL” is usually the better option.
SURROUND MODE
From the OSD’s <MAIN MENU> screen, select the <SURROUND MODE> line using the HTR L70 remote’s
, and “Enter” keys. Using the
and
keys you can select mode variations, and adjust
various parameters, depending on the current SURROUND MODE. For more information, see “About the
L70’s SURROUND MODEs,” below.
LEVEL TRIM (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.

Setup
SPEAKER CONFIGURATION
SETTING LEVEL TRIM
Press the HTR L70 remote’s “TEST” key, activating the L70’s channel-balancing test signal and displaying
the <TEST TONE> menu on the OSD. You will hear a “surf” sound that cycles through your speakers,
beginning with the Front-Left. (If you do not hear the test signal, check your speaker connections (above),
and your <SPEAKER CONFIGURATION> 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; 10 dB adjustment is available.
NOTE
•
If you are balancing levels “by ear,” choose one speaker – usually the centre – 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.
•
•
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 L70’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.
•
DELAY TIME
Your system’s SPEAKER CONFIGURATION settings are a subtle but important refinement of your setup.
Informing the L70 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the
correct delays, optimising imaging, intelligibility, and surround-sound ambience.
SETTING SPEAKER DELAY TIME
From the OSD’s <MAIN MENU> screen, select the <SURROUND MODE> item using the remote’s
and “Enter” keys. Using the
keys, select the surround mode you wish to configure. From your
principal listening position to the front surface of the centre loudspeaker select the amount of delay for
that particular surround mode. The delay in milliseconds roughly represents the distance in feet; one
millisecond is approximately one foot.

Operation
USING THE L70
You may operate the L70 DVD Surround Sound Receiver from its front panel or via the HTR L70 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 L70’s remote’s “Amp” device selected, the remote’s numeric-key section directly selects the
receiver’s internal DVD and tuner “TUNER”, as well as the other inputs and multichannel input (“Ext. 5.1”)
refer to the orange labels directly above each key.
•
•
When a source other than the internal DVD is selected, the video signal at the monitor output is always
a black background, until the internal DVD is selected.
When you change sources, the VFL will display the new input in its primary display.
ADJUSTING THE VOLUME
Use the HTR L70 remote’s <Volume up/down> keys to adjust the “master volume” of the L70, raising or
lower all channels together.
NOTE
•
A momentary keypress will change the master volume by 1 unit increments; if you hold down
<Volume up/down> the master-volume change will “run-on” until the key is released.
The L70’s OSD will show the volume setting as a line graphic with a numeric display above 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 L70 remote or the front-
panel knob automatically releases the mute function.
•
The L70 will power-up from standby mode at whatever master volume setting was last used; however,
if the prior setting was greater than 50 the L70 will power up to 50. This prevents inadvertently
beginning a session at excessive volume.
MUTING THE SOUND
Use the HTR L70 remote’s <Mute> key to silence all channels completely. Muting is always available,
regardless of source or SURROUND MODE selections.
NOTE
•
Cycling through standby or powering off releases muting; the L70 will return from standby with
muting off if standby was invoked with muting on.
•
•
A changing input or listening-mode selection releases muting.
Adjusting the master-volume via the HTR L70 or the front-panel knob automatically releases the mute
function.

Operation
USING THE L70’S AM/FM RADIO
The L70’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 adaptor, 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 optimise 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.
SELECTING THE RADIO
Press the AM/FM key on the L70 front panel, the HTR L70’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

Operation
USING THE L70’S AM/FM RADIO
CHOOSING THE FM MUTE / MODE
The front-panel FM MUTE/Mode key is a dual-purpose control. First, it “toggles” the L70 between stereo
mute and unmuted mono 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. 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
Toggling between FM Mute on or off also defeats the L70’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 L70 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 favourite stations will not
be broadcasting RDS data.
VIEWING RDS TEXT
When an RDS-enabled FM broadcast is tuned, after a brief delay the “RDS” symbol will light in the L70’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 DISPLAY key for about four seconds; the readout shows a blinking bar. Use the PRESET
keys
to select the first character of the name (“N” from the alphabetic list; press either TUNE key 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 THE L70’S SURROUND MODES
The L70 receiver offers nine distinct SURROUND 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 SURROUND MODEs can be selected:
•
•
•
Dolby PRO LOGIC II MOVIE
Dolby PRO LOGIC II MUSIC
Dolby PRO LOGIC II EMULATION
Two-channel recordings, whether stereo or surround-encoded, are reproduced with ProLogic II surround
processing, yielding output to left-, centre-, and right-front channels, discrete left/right surround channels,
and subwoofer (assuming these are present in the current <SPEAKER CONFIGURATION>).
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 L70 provides three Pro Logic II variations: MOVIES, MUSIC and EMULATION. See “Adjusting
SURROUND MODES”.

Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD
surround processing with signals output to the left, centre-, and right-front channels and discrete left/right
surround channels, plus subwoofer (assuming these are present in the current <SPEAKER
CONFIGURATION>). 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
All recordings reproduced in stereo (Downmix, from Dolby Digital/DTS multichannel sources) are
reproduced via the maximum speaker complement configured in the current <SPEAKER
CONFIGURATION>). Enhanced-Stereo can be useful for maximum volume from all channels, or for multi-
speaker background music (cocktail party) listening.
STEREO
All recordings reproduced in stereo (Stereo, or Downmix, from Dolby Digital/DTS multichannel sources)
are reproduced via the front speakers only (plus subwoofer, if any). Stereo can prove useful in certain late-
night or very low-volume listening situations.
The following Surround Sound Modes require a specially encoded signal that must be present in digital format
to be decoded by the L70. These modes are automatically switched on when the appropriate data stream is
detected. The desired data stream must sometimes be selected in the setup menu of the source media.

ABOUT THE L70’S SURROUND MODES
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 CONFIGURATION> setup).
NOTE
•
•
The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output. The DVD
includes its own setup menu that (among other things) lets you select the default bit-stream format,
and 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 “DOLBY
DIGITAL: ON”. 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.
While most Dolby Digital recordings are 5.1-channel surround productions, older examples may be
multichannel, 2-channel, or even monaural; the L70 will automatically reproduce the Dolby Digital
signal with the maximum number of channels available.
The table below indicates which SURROUND 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 SURROUND MODE is not available to
a given signal source, it will not appear in the <SURROUND MODE> selection rotation.

SELECTING SURROUND MODES
Keying the HTR L70 remote’s “SURR MODE” button steps through each of the L70’s SURROUND MODEs
available to the current input signal. It also momentarily displays the SURROUND MODE in the OSD.
NOTE
Changing the type of input signal may automatically change the SURROUND 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.

ABOUT THE L70’S SURROUND MODES
ADJUSTING LEVEL TRIM “ON THE FLY”
You can make changes to the relative levels of centre, 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 centre channel, or to reduce excessive deep bass (or enhance deep bass) by lowering
(raising) the subwoofer level without having to go into the LEVEL TRIM OSD menu.
TO ADJUST LEVEL TRIM
Use the HTR L70 remote’s “SURR”, “CENTER”, and “SUB”
keys for direct-access level adjustment of
these channels, over a range of 10 dB. You can also adjust all channel levels using the front panel’s
navigation keys (see “Front Panel,” above), or via the <LEVEL TRIM> line of the OSD’s <MAIN MENU> screen.
NOTE
•
The surround channels (if any) adjust in tandem. Channel Level changes made via the HTR L70 are
retained even if you cycle the receiver through standby.
•
Level settings are added/subtracted to the setup levels established by the L70 level-calibration routine,
invoked by the HTR L70 “Test” key.
ADJUSTING THE TONE CONTROLS
The L70 bass and treble controls are adjusted using the front panel’s TONE button in conjunction with the
VOLUME knob; see “Front Panel,” above.
NOTE
Bass/treble settings affect only the front left/right channels, and are active in all SURROUND MODEs.
ABOUT THE 12 V TRIGGER OUT
The L70’s rear-panel 12 V TRIGGER OUT is a convenient method of controlling on and off any auxiliary
equipment that is connected to or is used in conjunction with the L70, when the L70 is turned on or to
standby via remote or the front panel power button.
12 V TRIGGER OUT
The L70’s rear-panel 12 V TRIGGER OUT is a female miniature 3.5 mm stereotype jack that will produce +12
V DC at approximately 50 mA. Use a 3.5 mm stereotype miniature phone plug with the centre pin + 12 V
and the first band the ground. We recommend that you use a good quality cable with shield when attaching
the 3.5 mm stereotype plug so as to prevent false triggering of the auxiliary equipment due to electro-
magnetic interference from nearby electronic equipment. See your NAD audio specialist for more information.

Contains pre-programmed library of NAD remote codes for the L70.
The NAD HTR L70 is ready to operate the L70 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 L70 is already preprogrammed with a full complement of commands for the L70 receiver on its
“AMP”, “TUNER” and “DVD” 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 L70 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 L70, it should not be necessary to re-program any keys on the HTR L70 “AMP” and
“DVD” page. However, in order for the HTR L70 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 L70
The HTR L70 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 L70 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 L70.
However, the HTR L70 is already preprogrammed to operate the L70. All of the function keys on the
“AMP”, “TUNER” and “DVD” Device Selector “page” perform L70 functions. (The HTR L70 can also
command many other NAD components, from its “CD” and “TAPE” pages.)
It is important to note that certain HTR L70 keys perform different functions depending on the selected
Device Selector “page.” The colour of the Device Selector key-labelling corresponds to the labelling of the
function keys. Most centrally, the orange “AMP” Device Selector “page” corresponds to the orange
input-select labelling adjacent to the numeric keys: When the HTR L70’s “AMP” Device Selector page is
active, these keys select the receiver inputs. Similarly, the red “DVD” Device Selector “page” corresponds
to several red labels, the green “TV” page to green labels, and so on.

Operation
USING THE HTR L70 REMOTE CONTROL
LEARNING CODES FROM OTHER REMOTES
Begin by positioning the HTR L70 “nose-to-nose” with the source remote so the two devices’ infrared
windows are about 2 inches apart.
•
Enter Learning Mode: On the HTR L70, simultaneously press-and-hold for 3 seconds both a Device
Selector key and the “OPEN/CLOSE” key (just below the “DISP” key), until the Learn LED at
the centre of the HTR L70 turns steady green.
•
•
Press the HTR L70’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 L70’s Learn LED will flicker amber
for a second or two, then turn solid green. The command is learned.
•
Press the HTR L70’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 process is
complete; the Learn LED will turn red.
Example: Learning “VCR Pause”:
Position the HTR L70 and your VCR player’s remote as described above.
•
On the HTR L70, simultaneously press-and-hold “VCR” and
green.
; the Learn LED turns steady
•
•
Press the HTR L70’s
(pause) key; the Learn LED turns amber.
Press-and-hold the VCR player’s remote’s pause key; the HTR L70’s Learn LED flickers amber and
then turns solid green. The command is learned.
•
Press “VCR” again to exit the learning mode.
PUNCH-THROUGH
The HTR L70’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 L70
when the DVD Device Selector page is active
NOTE
The HTR L70’s “VOL” and “MUTE” keys are pre-programmed as “punched-through” for all Device
Select pages: “VOL” will operate the L70’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 L70, simultaneously press-and-hold “DVD” and
turns steady green.
(OPEN/CLOSE); the Learn LED
•
•
•
Press “SURR MODE”; the Learn LED turns amber.

COPY A COMMAND FROM ANOTHER KEY
You may copy a command from any HTR L70 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 DVD page to the AMP
key:
•
On the HTR L70, simultaneously press-and-hold “AMP” and
turns steady green.
(OPEN/CLOSE); the Learn LED

•
•
Press
Press “CD”; press
Press “AMP” again to exit the learning mode.
(pause); the Learn LED turns amber.
(pause); the Learn LED turns green.
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 SURROUND MODE, and begin playback-again, all from a single keypress. The HTR L70
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 L70
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 L70, Select the DVD Input, and
Commence Playback:
•
•
•
On the HTR L70, simultaneously press-and-hold “MACRO” and “0” (numeric zero); the Learn LED
turns steady green.
Press “AMP”; press “ON”; press “1” (orange “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.

Operation
USING THE HTR L70 REMOTE CONTROL
EXECUTING MACROS
To execute a macro, press and release “MACRO”; its key illumination lights for 5 seconds. While it remains
lit, press an HTR L70 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 L70 key while a macro is executing will
abort the macro. Remember that you must hold the HTR L70 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.
KEY-ILLUMINATION TIMEOUT
The HTR L70’s key-illumination can be set to remain lit for 0-9 seconds. The default value is 5 seconds.
To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR L70’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 L70’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 L70 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 L70’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 L70 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 L70 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 L70 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 L70 to control is plugged in and powered-up
(“on,” not merely in standby). To enter the HTR L70’s Library Mode, simultaneously press-and-hold for 3
seconds both the desired Device Selector key and the “PROGRAM” key, until the Learn LED turns green.
While keeping the HTR L70 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.

SEARCH MODE
If none of the codes from the table turn off 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 “PROGRAM” key, until the Learn LED turns green. Now press-and-hold the HTR L70’s
or
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
L70’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 “PROGRAM” key, until the Learn LED turns green. Press the “DISP” key; the HTR L70 indicates the
current code-library by flashing its “TAPE”, “VCR”, and “MACRO” keys. For example, to indicate code-
library #501 the HTR L70 will flash “TAPE” 5 times, pause, and then flash “MACRO” once. You might
wish to make a note of your components’ code-library numbers.
