INTRODUCTION

GETTING STARTED

UNPACKING AND SETUP

WHAT’S IN THE BOX

Packed with your C 715 you will find:

• 

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.

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!

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. 

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.  

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.

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. 

• 

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.

• 

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.

• 

Insert the media and press the   button to start playback. 

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:

• 

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 C 715. That is

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. 

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.

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

Turn oFF C 715 by pressing the power button in the front panel or SR 7 
remote control’s [oFF] key.

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.

Please note that setting the C 715 to factory default will delete all AM, FM 
and DAb presets.
