2. POWER / STAND-BY / PROTECTION INDICATOR
Upon switching Power on, the indicator will light up amber in standby
state. While one of the input select buttons is pressed, the LED will turn
red for a moment, then turn green for ON state. 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, the indicator will light up red and the sound will be 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, switch the amplifier On again.
The diagram below shows the operation of the Stand-by / protection
indicator:

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
counter-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.
NOTES: When a command from the remote control is received, the
Stand-by/protection indicator will blink. Note that the indicator may also
blink when receiving commands not necessarily for the C 352 but for
other components in the system.
Direct sunlight, very bright or fluorescent 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 C 352 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 indicators just above
each button show 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.
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 indicator to show Tape 1 is engaged, the green
indicator for the active input will also stay lit.
NOTE: The remote control handset with the C 352 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 C 352. The Video 2 and Video 3 input selector buttons
on the remote control handset are inoperative in the case of the C 352.
6. SOFT CLIPPING™ INDICATOR
The green SOFT CLIPPING™ indicator shows that the Soft Clipping™
mode is engaged. Refer also to chapter "Rear Panel Connections",
section 12; "Soft Clipping™" for more information.
7. BASS & TREBLE CONTROLS
The NAD C 352 is fitted with BASS and TREBLE tone controls to adjust
the tonal balance of your system. The 12 o'clock position is 'flat' with
no boost or cut and a detent indicates this position. Rotate the control
clockwise to increase the amount of Bass or Treble. Rotate the control
anti-clockwise to decrease the amount of Bass or Treble. The Tone
controls do not affect recordings made using the Tape outputs but will
affect the signal going to the Pre-amp output (Pre Out).
8. TONE DEFEAT
The TONE DEFEAT switch bypasses the tone control section of the NAD
C 352. If the Tone Controls are not normally used and left in the 12
o'clock position, then it is advisable to switch out the Tone Control
section altogether by using this switch. In the 'out' position, the Tone
Control circuits are active, pushing the TONE DEFEAT switch 'in'
bypasses the Tone Control section.
