NOTES ON INSTALLATION
Your NAD C320 should be placed on a firm, level surface. Avoid
placing the unit in direct sunlight or near sources of heat and
damp. Allow adequate ventilation. Do not place the unit on a soft
surface like a carpet. Do not place it in an enclosed position such
a bookcase or cabinet that may impede the air-flow through the
ventilation slots. Make sure the unit is switched off before making
any connections.
The RCA sockets on your NAD C320 are colour coded for
convenience. Red and white are Right and Left audio respectively,
and yellow for NAD Link.
Use high quality leads and sockets for optimum performance and
reliability. Ensure that leads and sockets are not damaged in any
way and all sockets are firmly pushed home.
For best performance, use quality speaker leads of 16 gauge
(1.5mm) thickness or more. If the unit is not going to be used for
some time, disconnect the plug from the AC socket.
Should water get into your NAD C320, shut off the power to the
unit and remove the plug from the AC socket. Have the unit
inspected by a qualified service technician before attempting to
use it again. Do not remove the cover, there are no user-
serviceable parts inside.
Use a dry soft cloth to clean the unit. If necessary, lightly dampen
the cloth with soapy water. Do not use solutions containing benzol
or other volatile agents.

sources to the relevant rear input sockets.
2. Plug in the AC power cord.
3. Press the POWER button to turn the NAD C320 on.
4. Press the required input selector.
REAR PANEL CONNECTIONS
1. NAD LINK IN, OUT
The NAD-Link connector is used to pass commands from other
units fitted with NAD-Link connectors. This allows centralised
control of a complete system, and also allows some of the basic
functions of other NAD components (such as a tuner, CD player or
cassette-deck) also equipped with NAD-Link to be controlled with
the amplifier's remote control. To function with such other units,
connect the C320's NAD-Link Out to the NAD-Link In on the other
unit. NAD-Link connectors can be daisy-chained, IN to OUT, so
that a whole system can be controlled from the remote control
facilities of one unit.
2. DISC INPUT
Input for additional line level input signals such as CD, Mini Disc
player or the output signal from a step-up amplifier for a
turntable. Use a twin RCA-to-RCA lead to connect the auxiliary
unit's left and right `Audio Outputs' to this input.
3. CD INPUT
Input for a CD or other line-level signal source. Use a twin RCA-
to-RCA lead to connect the CD player's left and right `Audio
Outputs' to this input. The NAD C320 only accepts analogue
signals from your CD player.
4. VIDEO INPUT
Input for the audio signal from a stereo VCR (or stereo
TV/Satellite/Cable receiver) or other line-level audio source.
Using twin RCA-to-RCA leads, connect to the left and right `Audio
Outputs' of the unit to these inputs. Note: These are audio inputs
only.
5. AUX INPUT
Input for additional line level input signals such as another CD
player. Use a twin RCA-to-RCA lead to connect the auxiliary unit's
left and right `Audio Outputs' to this input.
6. TUNER INPUT
Input for a tuner or other line-level signal source. Use a twin RCA-
to-RCA lead to connect the tuner left and right `Audio Outputs' to
this input.
7. TAPE 2 IN, OUT
Connections for analogue recording and playback to an audio
tape recorder of any type. Using twin RCA-to-RCA leads, connect
to the left and right `Audio Output' of the tape machine to the TAPE
2 IN sockets for playback and tape monitoring. Connect the left
and right `Audio Input' of the tape machine to the TAPE 2 OUT
sockets for recording.
8. TAPE 1 IN, OUT
Connections for analogue recording and playback to an audio
tape recorder of any type. Using twin RCA-to-RCA leads, connect
to the left and right `Audio Output' of the tape machine to the TAPE
1 IN sockets for playback and tape monitoring. Connect the left
and right `Audio Input' of the tape machine to the TAPE 1 OUT
sockets for recording.
9. PRE OUT
Connections to an external power amplifier or processor, such as
a surround-sound decoder. In normal use these should be
connected to the Main-In sockets (No. 10) with the links
supplied. To connect your NAD C320 to external processor or
amplifier sections first remove these links. Use a twin RCA-to-RCA
lead to connect to the left and right `Audio Input' of the Power
amp or processor to the Pre Out sockets.
NOTE: The Pre-Out output signal will be affected by the NAD
C320's volume and tone control settings, always turn the amplifier
off before connecting or disconnecting anything from to Pre-Out
and Main-In sockets.
10. MAIN IN
Connections to an external pre-amplifier or processor, such as a
surround-sound decoder. In normal use these should be
connected to the Pre-Out sockets (No. 9) with the links supplied.
To connect your NAD C320 to external processor or pre-amplifier
first remove these links. Use a twin RCA-to-RCA lead to connect to
the left and right `Audio Output' of the pre-amp or processor to
the Main-In sockets.
NOTE: Always turn the amplifier off before connecting or
disconnecting anything from to Pre-Out and Main-In sockets.

11. SPEAKERS
Speaker terminals for speakers with an impedance of 4 ohms or
more. Connect the right speaker to the terminals market `R +' and
`R-' ensuring that the `R+' is connected to the `+' terminal on your
loudspeaker and the `R-' is connected to the loudspeaker's `-'
terminal. Connect the terminals marked `L+' and `L-' to the left
speaker in the same way.
Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire
to connect loudspeakers to your NAD C320. The high-current
binding post terminals can be used as a screw terminal for cables
terminating in spade or pin sockets or for cables with bare wire ends.
BARE WIRES AND PIN CONNECTORS
Bare wires and pin sockets should be inserted into the hole in the
shaft of the terminal. Unscrew the speaker terminal's plastic
bushing until the hole in the screw shaft is revealed. Insert the pin
or bare cable end into the hole and secure the cable by tightening
down the terminal's bushing.
Ensure bare wire from the speaker cables does not touch the back
panel or another socket. Ensure that there is only 1/2" (1cm) of
bare cable or pin and no loose strands of speakers wire.
12. SOFT CLIPPING
When an amplifier is driven beyond its specified power output, a
hard, distorted sound can be heard on very loud sounds. This is
caused by the amplifier cutting off or `hard clipping' the peaks of
sound that was not designed to reproduce. The NAD Soft Clipping
circuit gently limits the output of the system to minimise audible
distortion if the amplifier is overdriven.
If your listening involves moderate power levels you may leave the Soft
Clipping switch to Off. If you are likely to play at high levels, that could
stretch the amplifier's power capability, then switch Soft Clipping On.
The Soft Clipping LED on the front panel will illuminate when the
amplifier is in Soft Clipping mode.
13. 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.
FRONT PANEL CONTROLS
1. POWER
Pressing the Power switch turns the unit ON. Upon switching the
amplifier on, it will choose CD as the active input.
The LED for the CD will light up, after flashing for a couple of
seconds. Pressing the POWER switch again will turn the amplifier off.
NOTE: The remote control handset supplied with the C320 is of a
universal NAD type, designed to operate several NAD models.
Some buttons on this handset are inoperative as the functions
aren't supported by the C320. The Green On/Off button on the
remote control handset is inoperative in the case of the C320.
2. POWER/PROTECTION LED
Upon switching the power on, the LED will light up red for a few
seconds before the protection circuit is deactivated. The LED will then
turn green, and the amplifier is ready for normal operation.
In cases of serious abuse of the amplifier, such as overheating,
excessively low loudspeaker impedance, short circuit etc. the amplifier
will engage its Protection circuitry, indicated by the LED turning from
green to red, and the sound being muted. In such a case, turn the
amplifier off, wait for it to cool down and/or check the speaker
connections, making sure the overall loudspeaker impedance doesn't
go below 4 ohms. Once the cause for the protection circuitry to engage
has been removed, press Power again to resume normal operation.
3. HEADPHONE SOCKET
A 1/4" stereo jack socket is supplied for headphone listening and
will work with conventional headphones of any impedance.
Inserting a headphone jack into this socket automatically switches
off the loudspeakers. The volume, tone and balance controls are
operative for headphone listening. Use a suitable adapter to
connect headphones with other types of sockets, such as 3.5mm
stereo `personal stereo' jack plugs.
NOTE: Make certain that the volume control is turned to
minimum (fully anti-clockwise) before connecting or
disconnecting headphones. Listening at high levels can damage
your hearing.
4. INFRA-RED REMOTE CONTROL COMMAND
RECEIVER
The infrared sensor, located behind this circular window, receives
commands from the remote control. There must be a clear line-
of-sight path from the remote control to this window; if that path
is obstructed, the remote control may not work.
NOTE: Direct sunlight or very bright ambient lighting may affect
the operating range and angle for the remote control handset.
5. INPUT SELECTORS
These buttons select the active input to the NAD C320 and the
signal sent to the loudspeakers, the Tape outputs and the PRE OUT
sockets. The buttons on the remote control handset duplicate
these buttons, with the exception of the tuner input; see below.
Green LEDs just above each button will indicate which input is
currently selected.
DISC Selects a line-level source connected to the DISC sockets as
the active input.
CD Selects the CD (or other line-level source) connected to the
CD sockets as the active input.
VIDEO Selects the VCR (or stereo TV/Satellite/Cable receiver)
connected to the VIDEO sockets as the active input.
AUX Selects a line-level source connected to the AUX sockets as
the active input.
TUNER Selects the tuner (or other line-level source) connected
to the Tuner sockets as the active input. The remote control
handset has separate buttons for AM and FM; pressing either one
will select the C320's tuner input.
TAPE 2 Selects Tape 2 as the active input.
TAPE 1 Monitor Selects the output from a tape recorder when
playing back tapes or monitoring recordings being made through
the Tape 1 sockets. Press the Tape 1 button once to select it and
again to return to the normal input selection.
Tape 1 is a tape Monitor function which does not override the
current input selection. For example, if the CD is the active input
when TAPE 1 is selected, then the CD signal will continue to be
selected and sent to both the TAPE 2, and TAPE 1 OUTPUT sockets,
but it is the sound from recorder connected to Tape 1 that will be
heard on the loudspeakers. Apart from the amber LED to indicate
Tape 1 is engaged, the green LED for the active input will also stay lit.
NOTE: The remote control handset with the C320 supplied is of a
universal NAD type, designed to operate several NAD models.
Some buttons on this handset are inoperative as the functions
aren't supported by the C320. The Video 2 and Video 3 input
selector buttons on the remote control handset are inoperative in
the case of the C320.
