FRONT PANEL CONTROLS
1. POWER
Pressing the POWER switch turns the unit On. The LED will light
up red initially and within seconds will turn green. Pressing the
POWER switch again will turn the amplifier Off.
2. POWER/PROTECTION LED
Upon switching Power on, the LED will light up red for a few
seconds before the protection circuit is de-activated. The LED will
then turn green and the amplifier is ready for normal operation.
The LED will flash when the 'Mute' mode is selected (refer also to
section "9. Volume" and the chapter "Remote control").
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. BASS & TREBLE CONTROLS
The NAD C300 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 an indent
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.
5. TONE DEFEAT
The TONE DEFEAT switch by-passes the tone control section of the
NAD C300. 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.
6. BALANCE
The BALANCE control adjusts the relative levels of the left and right
speakers. The 12 o'clock position provides equal level to the left
and right channels. A detent indicates this position.
Rotating the control clockwise moves the balance towards the
right. Rotating the control anti-clockwise moves the balance to the
left. The BALANCE control does not affect recordings made using
the Tape outputs.
7. 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.
8. INPUT SELECTORS
These buttons select the active input to the NAD C300 and the
signal sent to the loudspeakers and the Tape outputs.
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.
9. VOLUME
The VOLUME control adjusts the overall loudness of the signals
being fed to the loudspeakers. It is motor driven and can be
adjusted from the remote control handset. The VOLUME control
does not affect recordings made using the Tape outputs.
On the remote control handset, press the MUTE Button to
temporarily switch off the sound to the speakers and headphones.
Mute mode is indicated by the Power/Protection LED flashing.
Press MUTE again to restore sound. Mute does not affect
recordings made using the Tape outputs.
TO MAKE A RECORDING
When any source is selected, its signal is also fed directly to any
tape machine connected to the TAPE 2 or TAPE 1 OUTPUTS for
recording.
TAPE TO TAPE COPYING
You can copy between two tape machines connected to your NAD
C300. Put the source tape in the recorder connected to Tape 2 and
the blank tape into the recorder connected to Tape 1. By selecting
TAPE 2 Input you can now record from Tape 2 to Tape 1 and
monitor the signal coming from the original tape.
