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 or it in an enclosed position such a bookcase or cabinet that may impede the air-flow through the ventilation slots. Make sure the unit and other components of your system are switched off before making any connections. The RCA sockets on your NAD C160 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. 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 C160, 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 1. MC INPUT Input for a Moving Coil phono cartridge. Connect the twin RCA lead from your turntable to this input if you are using a Moving Coil cartridge. 11. PRE OUT 1 The NAD C160 allows for the connection multiple power amplifiers. If you are using a single stereo power amplifier, use the PRE OUT 1 sockets. If you are using a pair of power amplifiers specifically for Biamping, use the sockets to connect the power amplifier with the lowest gain of the pair. 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 sockets. 12. PRE OUT 2 The PRE OUT 2 sockets can be used to drive an additional power amplifier. The VOLUME PRE OUT 2 control (13) 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. If you are using a pair of power amplifiers specifically for Biamping, 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 (13) the volume level can be matched exactly to that of the power amplfier 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 sockets. 4 6. 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. 7. 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. 8. TUNER INPUT Input for a Tuner or other line-level signal source. Use a twin RCAto-RCA lead to connect the Tuner left and right `Audio Outputs' to this input. 9. 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 and tape monitoring. Connect the left and right `Audio Input' of the tape machine to the TAPE 2 OUT sockets for recording. 10. 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 1OUT sockets for recording. GB 2. MM INPUT Input for a Moving Magnet phono cartridge. Connect the twin RCA lead from your turntable to this input if you are using a Moving Magnet cartridge. 3. MC-MM SWITCH Use this switch to select the phono input you are using. 4. PHONO GROUND CONNECTOR Often, the twin RCA leads from turntables also includes a single wire earth lead. Use the NAD C160 phono ground connector to connect this lead. Unscrew the terminal to expose the hole, which will accept the lead. After insertion, tighten the terminal to secure the lead. 5. CD INPUT Input for a CD or other line-level signal source. Use a twin RCAto-RCA lead to connect the CD player's left and right `Audio Outputs' to this input. The NAD C160 only accepts analogue signals from your CD player. 13. 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 by up 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. NOTE: always turn the pre-amplifier and associated power amplifiers off before connecting or disconnecting anything to the Pre-Out 1 & 2 sockets. 14. NAD LINK IN, OUT The NAD-Link connector is used to pass commands from other units fitted with NAD-Link connectors. This allows centralised control of a complete system, and also allows some of the basic functions of other NAD components (such as a CD player or cassette-deck) also equipped with NAD-Link to be controlled with the pre-amplifier's remote control. To function with such other units, connect the C160's NAD-Link Out to the NAD-Link In on the other unit. NAD-Link connectors can be daisy-chained, IN to OUT, so that a whole system can be controlled from the remote control facilities of one unit. 15. 12V TRIGGER OUT The 12V trigger is activated automatically when switching the NAD C160 from off or stand-by to on. Connect the 12V trigger to a power amplifier or AC outlet power strip equipped with a 12V trigger input for remote on/off switching of those devices. Use a cable terminated with a 3.5mm Mini-Jack connector at the preamplifier's end for connection. 16. AC LINE CORD Plug the AC power cord into a live AC wall socket.
