NOTES ON INSTALLATION

Your NAD C320BEE should be placed on a firm, level surface. Avoid placing the unit in direct sunlight or near sources of heat and damp. Allow adequate ventilation. Do not place the unit on a soft surface like a carpet. Do not place it in an enclosed position such a bookcase or cabinet that may impede the air-flow through the ventilation slots. Make sure the unit is switched off before making any connections.

The RCA sockets on your NAD C320BEE are colour coded for convenience. Red and white are Right and Left audio respectively, and yellow for NAD Link.

Use high quality leads and sockets for optimum performance and reliability. Ensure that leads and sockets are not damaged in any way and all sockets are firmly pushed home.

For best performance, use quality speaker leads of 16 gauge (1.5mm) thickness or more. If the unit is not going to be used for some time, disconnect the plug from the AC socket.

Should water get into your NAD C320BEE, shut off the power to the unit and remove the plug from the AC socket. Have the unit inspected by a qualified service technician before attempting to use it again.

DO NOT REMOVE THE COVER, THERE ARE NO USER-SERVICEABLE PARTS INSIDE.

Use a dry soft cloth to clean the unit. If necessary, lightly dampen the cloth with soapy water. Do not use solutions containing benzol or other volatile agents.

QUICK START

1 Connect the speakers to the rear Speaker terminals and sources to the relevant rear input sockets.
2 Plug in the AC power cord.
3 Press the POWER button to turn the NAD C320BEE on.
4 Press the required input selector.

FRONT PANEL CONTROLS

1 Power - Pressing the Power switch turns the unit to standby state. Upon selecting any input at the front panel or the ON button at the remote, the C320BEE will choose the last selected as the active input. The LED over the power switch will change form amber, indicating standby state, to green when any input is selected. Pressing the POWER switch again will turn the amplifier off.

NOTE

The remote control handset supplied with the C320BEE 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 C320BEE.

2 Power/Standby/Protection LED - Upon switching the power on, the LED will light up red for a few seconds before the protection circuit is deactivated. The LED will then turn amber, and the amplifier is ready for normal operation. 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 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.

5 Input selectors These buttons select the active input to the NAD C320BEE 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 LEDs just above each button will indicate 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 C320BEE'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 LED to indicate Tape 1 is engaged, the green LED for the active input will also stay lit.

NOTE

The remote control handset with the C320BEE 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 C320BEE. The Video 2 and Video 3 input selector buttons on the remote control handset are inoperative in the case of the C320BEE.

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 but will affect the signal going to the Pre-amp output (Pre Out).

8 Tone defeat - The TONE DEFEAT switch by-passes the tone control section of the NAD C320BEE. 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.
9 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 but will affect the signal going to the Pre-amp output (Pre Out).

10 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 will affect the signal going to the Pre-amp output (Pre Out).

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 active input LED flashing. Press the MUTE button again to restore sound. Mute does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

REAR PANEL CONNECTIONS

Connect the left and right 'Audio Input' of the tape machine to the TAPE 1 OUT sockets for recording.
9 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 C320BEE 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 C320BEE's volume and tone control settings, always turn the amplifier off before connecting or disconnecting anything from to Pre-Out and Main-In sockets.

10 Main in - 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 (No. 9) with the links supplied. To connect your NAD C320BEE 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.

11 Speakers - Speaker terminals for speakers with an impedance of 4 ohms or more. Connect the right speaker to the terminals market 'R +' and 'R-' ensuring that the 'R+' is connected to the '+' terminal on your loudspeaker and the 'R-' is connected to the loudspeaker's '-' terminal. Connect the terminals marked 'L+' and 'L-' to the left speaker in the same way.

Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire to connect loudspeakers to your NAD C320BEE. The high-current binding post terminals can be used as a screw terminal for cables terminating in spade or pin sockets or for cables with bare wire ends.

BARE WIRES AND PIN CONNECTORS

Bare wires and pin sockets should be inserted into the hole in the shaft of the terminal. Unscrew the speaker terminal's plastic bushing until the hole in the screw shaft is revealed. Insert the pin or bare cable end into the hole and secure the cable by tightening down the terminal's bushing. Ensure bare wire from the speaker cables does not touch the back panel or another socket. Ensure that there is only 1/2'' (1cm) of bare cable or pin and no loose strands of speakers wire.

12 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 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™ LED on the front panel will illuminate when the amplifier is in Soft Clipping mode.
13 AC line cord - Plug the AC power cord into a live AC wall socket. Make sure all connections have been made before connecting to mains.
14 12V trigger output - 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 C320BEE is on and 0V when the unit is either off or in standby. This output can drive a load up to 100ma at 12V.

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 C320BEE. 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.

REMOTE CONTROL HANDSET

The Remote Control handset handles all the key functions of the NAD C720BEE and has additional controls to remotely operate NAD Cassette and CD machines. It will operate up to a distance of 16ft (5m). Alkaline batteries are recommended for maximum operating life. Two AAA (R 03) batteries should be fitted in the battery compartment at the back of the Remote Control handset. When replacing batteries, check that they have been put in the right way round, as indicated on the base of the battery compartment.

Please refer to previous sections of the manual for a full description of individual functions.

When a command from the remote control is received, the Standby/protection indicator will blink.

1 POWER ON & OFF - The NAD C320BEE remote has a separate On and Off button. This can be particularly useful to keep components within a system "insync": 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 (Fig. 2; No. 2) will turn from amber, to red, then to green.
