THANK YOU FOR CHOOSING NAD
The C 715 DAb CD Receiver is a technologically advanced and highly
capable product-yet we have invested great effort in making it simple
and easy to use. The C 715 delivers a range of genuinely useful options
for stereo listening using powerful digital signal processing and superbly
accurate digital-audio circuitry. however, we have also been careful to
ensure that the C 715 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
C 715’s design, such that it can confidently promise you both state-of-the-
art 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 C 715.
one more thing: We urge you to register your C 715 ownership on the NAD

INTRODUCTION
GETTING STARTED
UNPACKING AND SETUP
WHAT’S IN THE BOX
DEALING WITH HUM AND NOISE
hum and noise sometimes may prove a challenge in audio systems. Note
these considerations to help prevent hum and noise problems:
Packed with your C 715 you will find:
•
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.
•
•
•
•
•
An AM loop antenna.
A FM lead-type antenna.
A F-type DAb antenna.
The SR 7 remote control with 2 (two) AAA batteries.
This owner’s manual.
•
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.
SAVE THE PACKAGING
Please save the box and all of the packaging in which your C 715 arrived.
Should you move or otherwise need to transport your C 715, 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!
•
•
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.
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 23 feet/7
meters, between the C 715’s front panel and your primary listening/viewing
position. This will ensure reliable infrared remote control communications.
The C 715 generates a modest amount of heat, but nothing that should
trouble adjacent components. It is perfectly possible to stack the C 715 on
top of other components.
Track down hum/noise problems one component at a time, working
backwards from the C 715. That is
1
2
Connect the speakers to the C 715 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 C 715 and check
for hum.
3
QUICK START
In case you simply cannot wait to experience the performance of your new
NAD C 715 CD Receiver, we provide the following“Quick Start”instructions
to get you underway.
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.
Please make all the connections to your C 715 with the unit unplugged.
It is also advisable to power-down or unplug all associated components
while making or breaking any signal or AC power connections.
FACTORY DEFAULT SETTINGS
Sometimes power spikes and drop-outs may from time to time cause some
inadvertent functionality. The procedure below will set the C 715 to factory
default settings
PLAY A CD
•
Connect your left and right front speakers to the C 715’s“l”and“R”
outputs. Make sure to connect red to red (“+”) and black to black (“-”)
with care to avoid stray wires or strands crossing between terminals.
If your system includes a powered subwoofer, connect the C 715’s
“SUbWooFER oUT”jack to its line input.
1
Turn oFF C 715 by pressing the power button in the front panel or SR 7
remote control’s [oFF] key.
2
Press and hold front panel’s [FM MoDE / ] key for more than two
seconds. The C 715 will switch itself back oN and all the settings are
restored to factory default settings.
•
Plug the AC mains plug into the AC outlet; the lED on the front panel
will be illuminated amber indicating the C 715 is in standby mode ready
to accept commands from either the front panel power switch or the
SR 7 remote.
Please note that setting the C 715 to factory default will delete all AM, FM
and DAb presets.
•
•
To start CD playback, toggle [SoURCE] button in the front panel until
“CD”mode or press directly SR 7’s [CD] source key. Press for the disc
tray to draw open.

FM MODE/ (PAUSE) [ ] : In FM mode, this button will toggle between
FM Stereo and FM Mono. The front panel [FM MoDE] key is a dual-
purpose control. In the normal position, (“STEREo”and“TUNED”icons
are illuminated in the VFD) only the stations with a strong signal can be
listened to and the noise between stations is muted.
If the disc tray is open and the C 715 is powered oFF, the disc tray will
draw close and the unit powered oFF.
Pressing the [FM MoDE] button again (“STEREo”icon is extinguished;
only“TUNED”is illuminated) allows distant and potentially noisy stations
to be received. Noise is reduced 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 stereo effect.

ATTENTION!
Please make sure that the C 715 is powered off or unplugged before making any connections. It is also advisable to power down or unplug all associated
components while making or breaking any signal or AC power connections.
1
SPEAKERS: Connect the left and right terminals to the corresponding
loudspeakers. Make sure that the “+”(red) terminal and“-”(black)
terminal are 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.
4
TAPE IN/OUT: Connections for analog recording and playback to an
audio tape recorder of any type. Using twin RCA-to-RCA leads, connect
the left and right“Audio output”of the tape machine to the C 715’s
TAPE IN sockets for playback and tape monitoring. Connect the left and
right“Audio Input”of the tape machine to C 715’s TAPE oUT sockets for
recording.
NOTES
•
Use stranded wire of at least 16-gauge (AWG); specialized speaker cable
NOTE
There will be no output at TAPE OUT when TAPE is selected. Likewise,
may be valuable (consult your NAD audio specialist). Connections to the
C 715 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. To minimize the danger of short-circuits,
ensure that only 1/2-inch of exposed wire or pin is employed in
connecting.
This unit is designed to produce optimum sound quality when
connected to speakers with impedances within the receiver’s operating
range. Please check that speakers are rated to be 6 ohms minimum per
speaker.
there will be no output at VIDEO OUT when VCR is the active source
input. This prevents feedback through the recording component thereby
preventing possible damage to your speakers.
5
6
VCR IN/OUT: VCR may be used with recording components such
as a cassette deck. Connect analog stereo audio from such source
components into the C715’s VCR IN. Connect the C 715’s VCR oUT to
the source components’record-input. Note that VCR may freely be used
for play-only components, in which case the oUT jacks would remain
unconnected.
•
2
FM / AM / DAB ANTENNA INPUT: Connect the supplied lead-type
FM antenna to the FM antenna input. Extend the lead. Experiment freely
with your antenna placement and orientation until you get the clearest
sound and lowest background noise. Fix the antenna in the desired
position by using thumb tacks, push pins or any suitable means.
AUX IN: Input for additional line level input such as another CD player.
Use a twin RCA-to-RCA lead to connect the auxiliary unit’s left and right
“Audio output”to this input.
7
8
SUBWOOFER OUT: Connect this output to a powered (“active”)
subwoofer (or to a power amplifier channel driving a passive system).
The AM loop antenna supplied with the C 715 (or a suitable
replacement) is required for AM reception. open the clip terminal
lever; insert the wire making sure to match the color-coded (white
and black) ends of the wire to that of the terminal and close the
lever 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.
AC LINE CORD: Plug the AC power cord into a live AC wall socket.
Make sure all connections have been made before connecting to mains.
Connect the supplied F-type DAb antenna to the DAb antenna input.
3
OPTICAL DIGITAL OUT: Connect the oPTICAl DIGITAl oUT port to
the corresponding S/PDIF digital input of a compatible device such as
CD recorders, receivers, computer soundcard or other digital processors.

“00:00”will be displayed”.
Pressing the [FM MoDE] button again (‘STEREo”icon is extinguished; only
“TUNED”is illuminated) allows distant and potentially noisy stations to be
received. Noise is reduced 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 stereo effect.
RDS PROGRAM TYPE
Program Type (PTy) allows users to find similar programming by genre.
Please find the section below about“PRoGRAM TyPE (PTy)”for more
information about RDS Program Type.
