If Speakers A and B are both engaged (both indicators over the Speakers A and B buttons are lit), the amplifier's output power is fed to both sets of speakers in parallel. If speakers A and B are disengaged, both sets of speakers are silenced. You can use this setting mode to listen to headphones (No. 3).
NOTES: Always turn the volume down when engaging or disengaging either Speaker A or Speaker B. When using Speakers A and B at the same time, make sure that the total impedance of the speakers connected is more than 8 ohms. Refer to the table below:
Bridge Mode | Stereo Mode |
One speaker 8Ω | minimum | One speaker 4Ω | minimum |
Two speakers 16Ω | minimum | Two speakers 8Ω | minimum |
5. INPUT SELECTORS
These buttons select the active input to the NAD C370 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 C370'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, 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 C370 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 C370. The Video 2 and Video 3 input selector buttons on the remote control handset are inoperative in the case of the C370.
6.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 C370 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.
7. SOFT CLIPPING™ INDICATOR
The green SOFT CLIPPING™ indicator shows that the Soft
Clipping™ mode is engaged. Refer also to chapter "Rear Panel
Connections", section 13; "Soft Clipping™" for more information.
8. BASS & TREBLE CONTROLS
The NAD C370 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 counter-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 outputs (Pre-Out 1 & 2).
9. TONE DEFEAT
The TONE DEFEAT switch bypasses the tone control section of the NAD C370. 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.
10. 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 counter-clockwise moves the balance to the left. The BALANCE control does not affect recordings made using the Tape outputs but will affect the signal going to the Pre- amp outputs (Pre-Out 1 & 2).
11. 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 but willGB affect the signal going to the Pre-amp outputs (Pre-Out 1 &2).
12. BRIDGE MODE INDICATOR
The BRIDE MODE indicator lights up (amber) when the C370 is switched to Bridge Mode. Refer also to chapter "Rear Panel Connections", section 12, "Bridge Mode" for more information.
RECORDING
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 C370. 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.
