ENGLISH FRANÇAIS DEUTSCH ESPAÑOL ITALIANO PORTUGUÊS SVENSKA NOTES ON INSTALLATION Your NAD C 372 should be placed on a firm, level surface. Avoid placing the unit in direct sunlight or near sources of heat and dampness. Allow adequate ventilation. Do not place the unit on a soft surface like a carpet. Do not place unit 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 C 372 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 in. 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 C 372, 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. REAR PANEL CONNECTIONS (FIGURE 1) 1. DISC INPUT Input for additional line level input signals such as CD, Mini Disc player or the output signal from a step-up amplifier for a turntable. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio Outputs' to this input. 2. 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 C 372 only accepts analogue signals from your CD player. 3. 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 Out' of the unit to these inputs. Note: These are audio inputs only. 4.

TUNER INPUT Input for a Tuner or other line-level signal source. Use a twin RCA-to-RCA lead to connect the Tuner left and right 'Audio Outputs' to this input. 6. TAPE 2 IN, OUT Connections for analogue recording and playback to 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 2 IN sockets for playback. Connect the left and right 'Audio Input' of the tape machine to the TAPE 2 OUT sockets for recording. 7. TAPE 1 IN, OUT Connections for analogue recording and playback to a secondary 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 and tape monitoring. Connect the left and right 'Audio Input' of the tape machine to the TAPE 1 OUT sockets for recording. 8. PRE OUT 1 In normal use the PRE OUT 1 is connected to the Main-In sockets (No. 9) with the links supplied. The NAD C 372 allows for the connection of multiple power amplifiers. If you are using a single, external stereo power amplifier, disconnect the links to the Main-In sockets. The C 372's internal power amplifier is now disconnected. 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 sockets. NOTES: Always turn the C 372 and associated external power amplifiers off before connecting or disconnecting anything to the PREOUT 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. 9. MAIN IN Connections to an external pre-amplifier or processor, such as a surround-sound decoder. In normal use these are connected to the PreOut 1 sockets (No. 8) with the links supplied. To connect your NAD C 372 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. NOTES: Always turn the C 372 and associated external power amplifiers off before connecting or disconnecting anything to the PREOUT 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. 10. PRE OUT 2 The PRE OUT 2 sockets can be used to drive an additional power amplifier. The VOLUME Pre-Out 2 control (No. 11) can be used to reduce the output level of the pre-amplifier to the power amplifier by up to 12dB. With the VOLUME Pre-Out 2 control set to the maximum position (at the 0dB position), the output level will be identical to that of the PRE OUT 1 sockets. 4 12. BRIDGE MODE The NAD C 372 can be used as part of a higher power stereo or hometheatre 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 o ...
