NAD C 372 Volume PRE OUT, Bridge Mode, Soft Clipping, Trigger OUT, Speakers a + Speakers B

Page 5

If you are using a pair of power amplifiers specifically for Bi-Amping, use the PRE OUT 2 sockets to connect the power amplifier with the highest gain of the pair. By adjusting the VOLUME PRE OUT 2 control (No. 11) the volume level can be matched exactly to that of the power amplifier connected to the PRE OUT 1 sockets. Refer also to chapter "Bi-Amping" for more information. Use a twin RCA-to-RCA lead to connect to the left and right 'Audio Input' of the Power amp to the PRE OUT 1 & 2 sockets.

NOTES: Always turn the C 372 and associated external power amplifiers off before connecting or disconnecting anything to the PRE- OUT 1, 2 and MAIN-IN sockets.

The PRE-OUT 1&2 output signals will be affected by the NAD C 372's volume and tone control settings.

11. VOLUME PRE OUT 2

The VOLUME Pre-Out 2 control allows for adjustment of the output level of the PRE OUT 2 sockets. The output level can be reduced from 0dB to -12dB; when set to the maximum position (at the 0dB position), the output level will be identical to that of the PRE OUT 1 sockets. Refer also to chapter "Bi-Amping" for more information.

NOTES: Always turn the C 372 and associated external power amplifiers off before connecting or disconnecting anything to the PRE- OUT 1, 2 and MAIN-IN sockets.

The PRE-OUT 1&2 output signals will be affected by the NAD C 372's volume and tone control settings.

12. BRIDGE MODE

The NAD C 372 can be used as part of a higher power stereo or home- theatre system, by connecting adding additional power amplifiers. If the power amp section in the NAD C 372 is to be used to drive a single speaker, then use the Bridge switch to run the built-in Left and Right power amplifiers as a single channel, high power unit. Set the BRIDGE MODE switch to the 'Bridge' position and connect the speaker to the terminals marked 'L +' and 'R+' ensuring that the 'L+' is connected to the '+' terminal on your loudspeaker and the 'R+' is connected to the loudspeaker's '-' terminal. Connect the source to the Left MAIN-IN input.

In Bridged Mode the NAD C 372 will produce approximately 300W into an 8 ohm loudspeaker. In this mode, the amplifier sections will react as though the speaker impedance has been halved. Low impedance speakers (under 8 ohms) are not recommended when using Bridge Mode, as these may cause the amplifier's thermal cut-out to operate if played at high levels.

The Bridge LED on the front panel (Fig. 2; No. 2) will illuminate when the amplifier is in Bridge mode.

NOTES: Do not connect anything to the Right MAIN-IN input (No. 9) when Bridge Mode is selected. Always turn the C 372 and associated external power amplifiers off before connecting or disconnecting anything to the PRE-OUT 1, 2 and MAIN-IN sockets.

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. 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 372'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.

15. 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 372, connect the12V-trigger output of the C 372 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 372's 12V- trigger output. NAD components equipped with 12V input triggers are fully compatible with the C 372's 12V output trigger. The C 372's 12V- trigger output voltage is 12V DC. The total maximum current must not exceed 200mA. 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 372 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.

16. SPEAKERS A + SPEAKERS B

The NAD C 372 is equipped with two sets of speaker connectors. Use the Speakers A connectors for the 'main' speakers and use the Speakers B connectors for a second pair, for example, extension speakers located in another room.
