REAR PANEL CONNECTIONS (FIGURE 1)
1. IR IN, OUT
The IR IN/OUT connector is used to pass commands from other units
fitted with IR IN/OUT connectors. This allows centralized 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 IR IN/OUT to be controlled with the amplifier's remote
control. To function with such other units, connect the C 352's IR OUT
to the IR IN on the other unit. The IR connectors can be daisy-chained,
IN to OUT, so that a whole system can be controlled from the remote
control facilities of one unit.
NOTES: It is advisable not to connect IR IN/OUT if these units that have
their own built-in remote control command receiver and are positioned
together, in direct view from the remote control handset. If you are
unsure, try operating the products without IR IN/OUT first; If the unit
responds to the remote control command, it will not be necessary to
connect IR IN/OUT. Never loop the last unit back to the first NAD unit in
the IR IN/OUT chain. Unplug all units from the mains before connecting
or disconnecting IR IN/OUT.
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 C 352 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. 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 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 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 1
In normal use the PRE OUT 1 is connected to the Main-In sockets (No. 9)
with the links supplied. The NAD C 352 allows for the connection of
multiple power amplifiers. If you are using a single, external stereo
power amplifier, disconnect the links to the Main-In sockets. The
C 352's internal power amplifier is now disconnected. Use a twin RCAto-
RCA lead to connect to the left and right ‘Audio Input’ of the Power
amp to the PRE OUT 1 sockets.
10. PRE OUT 2
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. 11) with the links supplied. To connect your
NAD C 352 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 2 sockets.
NOTE: The Pre-Out 2 output signal will be affected by the NAD C 352’s
volume and tone control settings. Always turn the amplifier off before
connecting or disconnecting anything to the Pre-Out 2 and Main-In
sockets.

11. 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 2 sockets (No. 10) with the links supplied. To connect your
NAD C 352 to external processor or preamplifier 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 to the Pre-Out and Main-In sockets.
12. 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 C 352. The highcurrent
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.
13. 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 Clipping On.
The Soft Clipping™ indicator on the front panel will illuminate when the
amplifier is in Soft Clipping mode.
14. 12V TRIGGER OUT
This output allows to remotely switch on or off ancillary equipment such
as a tuner, power amplifier, etc. which are also equipped with a 12V
trigger input. This can also be an AC outlet power strip equipped with
a 12V trigger input. The 12V trigger output is activated whenever the
unit is switched to normal operational mode from Stand-by or Off.
For switching Stand-by/Power On of an external component through
the C 352, connect the12V-trigger output of the C 352 to the remote
component's DC input jack. The plug required is a standard 3.5mm
Mini-Jack plug ("mono"): The tip is the live or + connection, the shaft
of the input jack is the 12V-trigger - or ground connection.
NOTES: Check the specifications of the Trigger input terminal on the
other components to ensure these are compatible with the C 352's 12Vtrigger
output. NAD components equipped with 12V input triggers are
fully compatible with the C 352's 12V output trigger. The C 352's 12Vtrigger
output voltage is 12V DC. The total maximum current must not
exceed 100mA. Typically, NAD 12V input triggers draw less than 10mA
of current. Before making any connections to any 12V trigger input or
output, make sure all components are disconnected from the AC mains.
Failure to observe the above may result in damage to the C 352 or any
ancillary components attached to it. If in doubt over the connections,
installation and operation of the 12V trigger output consult your NAD dealer.
15. IEC AC MAINS (POWER) INPUT
The C 352 comes supplied with a separate AC Mains cable. Before
connecting the cable to a live wall socket ensure that it is firmly
connected to the NAD C 352's AC Mains input socket first. Always
disconnect the AC Mains cable plug from the live wall socket first,
before disconnecting the cable from the C 352 Mains input socket.
