NOTES ON INSTALLATION
Your NAD C340 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 or 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 C340 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 C340, 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.
QUICK START
1. Connect the speakers to the rear Speaker sockets and sources
to the relevant rear input sockets.
2. Plug in the AC power cord.
3. Press the POWER button to turn the NAD C340 on.
4. Press the required input selector.
REAR PANEL CONNECTIONS
1. 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.
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 C340 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
Out’ 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. 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.
7. TAPE 2 IN, OUT
Connections for analogue recording and playback to a secondary
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. 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. 9) with the links supplied.
To connect your NAD C340 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
C340’s volume and tone control settings, always turn the amplifier
off before connecting or disconnecting anything from to Pre-Out
and Main-In sockets.
9. 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. 8) with the links supplied.
To connect your NAD C340 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.
10. 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 it 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
Clip On.
The Soft Clipping LED on the front panel will illuminate when the
amplifier is in Soft Clip mode.
