On And Off Buttons; Headphone Socket - NAD C350 Owner's Manual

ON AND OFF BUTTONS (NO. 2)
Besides the On/Off toggle function of the green button (No. 1), the
NAD C350 also has a separate On and Off button. This can be
particularly useful to keep components within a system "in-sync":
This way all components will switch to stand-by when Off is
pressed or switch to operating mode when On is pressed, instead
of some components switching On when the amplifier is switched
to Stand-by. (Note that the other components have to be capable
of responding to the separate On and Off commands as well).
Press the ON button to switch the unit from Stand-by to the
operating mode; The Stand-by indicator (No. 2) will turn from
amber to green after a short pause and the indicator for the last
selected source will light up. Press the OFF button to switch the
unit to the Stand-by mode: The Stand-by indicator (fig. 1; No. 2)
will light up amber.
NOTE: In Stand-by mode the C350 uses very little power.
However, it is recommended that you switch the unit totally off if
it is not going to be used for more than a couple of days. Switch
off completely by pressing the POWER button on the front panel
(No. 1), all lights will extinguish.
2. STAND-BY/PROTECTION INDICATOR
Upon switching Power on, the indicator will light up red and after
a short pause turn to green to indicate the amplifier is ready for
use.
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 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.

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 C350 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 C350 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. The remote control
handset has separate buttons for AM and FM; pressing either one
will select the C350'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,
Red
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 C350 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 C350. The Video 2 and Video 3 input
selector buttons on the remote control handset are inoperative in
the case of the C350.
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 C350 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).
