SERVICING PRECAUTIONS

CAUTION : Before servicing the A/V Receiver covered by this service data and its supplements and addends, read and follow the SAFETY PRECAUTIONS. NOTE : if unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions in this publication, always follow the safety precautions. Remember Safety First:
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical Es devices are integrated circuits and some field effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an antistatic solder removal device. Some solder removal devices not classified a anti-static can generate electrical charges sufficient to damage ES devices. 5. Do not use freonpropelled chemicals. These can generate electrical charge sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil, or comparable conductive material). 7. lmmediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. Caution : Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handing unpackaged replacement ES devices. (Normally harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device.)

General Servicing Precautions
1. Always unplug the A/V Receiver AC power cord from the AC power source before: (1) Removing or reinstalling any component, circuit board, module, or any other assembly. (2) Disconnecting or reconnecting any internal electrical plug or other electrical connection. (3) Connecting a test substitute in parallel with an electrolytic capacitor. Caution : A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion hazard. 2. Do not spray chemicals on or near this A/V Receiver or any of its assemblies. 3. Unless specified otherwise in this service data, clean electrical contacts by applying an appropriate contact cleaning solution to the contacts with a pipe cleaner, cottontipped swab, or comparable soft applicator. Unless specified otherwise in this service data, lubrication of contacts is not required. 4. Do not defeat any plug/socket B+ voltage interlocks with which instruments covered by this service manual might be equipped. 5. Do not apply AC power to this A/V Receiver and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed. 6. Always connect test instrument ground lead to the appropriate ground before connecting the test instrument positive lead. Always remove the test instrument ground lead last.
Insulation Checking Procedure
Disconnect the attachment plug from the AC outlet and turn the power on. Connect an insulation resistance meter(500V) to the blades of the attachment plug. The insulation resistance between each blade of the attachment plug and accessible conductive parts (Note 1) should be more than 1M-ohm. Note 1 : Accessible Conductive Parts including Metal panels, Input terminals, Earphone jacks, etc.

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 arent supported by the C320BEE.

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 C320BEEs 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.
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.

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.
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 doesnt go below 4 ohms. Once the cause for the protection circuitry to engage has been removed, press Power again to resume normal operation.

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 loudspeakers - 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 terminals 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 terminals 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 amplifiers 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.
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. Press the OFF button to switch the unit to the Stand-by mode: The Stand-by indicator will light up amber. 2 INPUTS - The input selector buttons perform the same functions as the buttons labelled the same on the front panel. 3 Numeric Keys - The numeric keys allow for direct input of tracks for CD-players, and direct channel/preset access for the tuner. 4 MASTER VOLUME - Press the MASTER VOLUME or buttons to respectively increase or decrease the loudness level. Release the button when the desired level is reached. The motorised Volume Control on the front panel will indicate the level set. The Master Volume buttons do not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp outputs. 5 MUTE - Press the MUTE Button to temporarily switch off the sound to the speakers and headphones. Mute mode is indicated by the MUTE icon in the VFD. Press MUTE again to restore sound. Mute does not affect recordings made using the Tape output but will affect the signal going to the Preamp outputs. 6 TUNER CONTROL - TUNE or scans respectively higher or lower station frequencies for both AM and FM. PRESET or selects respectively higher or lower number station preset.

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.
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.
