7 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 was not designed to reproduce. The NAD Soft Clipping circuit gently limits the output of the system to minimize 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

8 SUBW OUT Connect the SUBW OUT output to a powered ("active") subwoofer (or to power amplifier channel driving a passive system). The subwoofer output roll-off frequency is 100 Hz at -3dB.

9 MAIN IN - Use these connections to an external pre-amplifier or processor, such as a surround-sound decoder. In normal use these

should be connected to the Pre-Out sockets with the links supplied. To connect your NAD C720BEE to external processor or pre-amplifier first remove these links. Use a twin RCA-to-RCA lead to connect to the left and right 'Audio Output' of the pre-amp or processor to the Main-In sockets.

NOTE:

Always turn the amplifier off before connecting or disconnecting anything from to Pre-Out and Main-In sockets.

10 PRE-OUT- Connections to an external power amplifier or processor, such as a surround-sound decoder. In normal use these should be connected to the Main-In sockets (No. 10) with the links supplied. To connect your NAD C720BEE to external processor or amplifier sections first remove these links. Use a twin RCA-to-RCA lead to connect to the left and right 'Audio Input' of the Power amp or processor to the Pre Out sockets.

NOTE

The Pre-Out output signal will be affected by the NAD C720BEE's volume and tone control settings, always turn the amplifier off before connecting or disconnecting anything from to Pre-Out and Main-In sockets.

11 RECORD OUT/ZONE 2 - Connect the left and right 'Audio Input' of the tape machine to the TAPE OUT sockets for recording. For use as a zone 2 source, connect the left and right "Audio Input" of an integrated amplifier line in sockets to these line level outputs.

12 TAPE IN - Connections for analogue playback of an audio tape recorder of any type. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Output' of the tape machine to the TAPE 1 IN sockets for playback.

13 AUX input - Input for additional line level input signals such as another CD player. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio Outputs' to this input.

14 VIDEO input - Input for the audio signal from a stereo VCR (or stereo TV/Satellite/Cable receiver) or other line-level audio source. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Outputs' of the unit to these inputs. NOTE: These are audio inputs only.

ABOUT THE C 720BEE

15 CD input - Input for a CD or other line-level signal source. Use a twin RCA-to-RCA lead to connect the CD player's left and right 'Audio Outputs' to this input. The NAD C720BEE only accepts analogue signals from your CD player.

16 DISC input - Input for additional line level input signals such as CD, Mini Disc player or the output signal from a step-up amplifier (such as the NAD PP2) for a turntable. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio Outputs' to this input.

17 IR Input / Output - This input is connected to the output of an IR (infrared) repeater (Xantech or similar), or the IR output of another component to allow control of the C720BEE from a remote location. Ask your dealer or custom installer for further details.

18 +12V TRIGGER OUT - The 12V TRIGGER OUTPUT is used for controlling external equipment that is equipped with a 12V trigger input. This output will be 12V when the C720BEE is on and 0V when the unit is either off or in standby. This output can drive a load up to 50mA at 12V.

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 720BEE's 12Vtrigger output. NAD components equipped with 12V input triggers are fully compatible with the C720BEE's 12V output trigger. 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 C720BEE 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.
