AM ANTENNA An AM wire antenna is supplied with the NAD-712 and is required for AM reception. Open the clip terminal lever and insert the wire from the antenna. (see fig. 2). Closing the lever will lock the wire in place. Test various positions for the antenna, but always ensure the loop is placed vertically for best reception. Placing the antenna vertically close to large metal items such as metal shelves or radiators may interfere with reception. 1. Connect the speakers to Speaker A, and any other sources to the relevant rear sockets. 2. Connect the AM and FM antenna. 3. Plug in the AC power cord. 4. Press the POWER button to turn the NAD-712 on. 5. Press an input selector, AM or FM button. NOTES ON INSTALLATION Your NAD-712 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. Switch the unit off before making any connections. The RCA connectors on your NAD-712 are colour coded for convenience. Red and white are Right and Left audio, and orange for NAD-Link. Use high quality leads and connectors for optimum performance and reliability of connection. Ensure that leads and connectors are not damaged in any way and all connectors are firmly pushed home. For best performance, use quality speaker leads of 16 gauge 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-712, 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 dampened the cloth with soapy water. Do not use solutions containing benzol or other volatile agents. 3. TAPE 2 IN/OUT Connections for analogue recording and playback to a secondary audio tape recorder of any type.

Using twin phono-to-phono leads, connect to the left and right `Audio Out' of the VCR/satellite receiver to these inputs. REAR PANEL CONNECTIONS 1. FM ANTENNA A ribbon wire FM antenna is included and should be connected to the FM connector at the rear of the unit using the `balun' adapter supplied. (see fig. 1) The ribbon aerial should be mounted on a vertical surface and placed so that it forms a `T'. Experiment with placement of the antenna to find the position that gives the best signal strength and lowest background noise. An inadequate FM signal normally results in high levels of hiss, especially in stereo, and interference from external electrical sources. In areas of poor FM reception, the tuner section's performance can be improved by using an externally mounted FM antenna. A qualified aerial installer will be able to advise and fit a recommended aerial for your reception conditions. NAD 4 8. TAPE 1 IN/OUT Connections for analogue recording and playback to an audio tape recorder of any type. Using twin phonoto-phono leads, connect to the left and right `Audio Output' of the tape machine to the TAPE 1 IN connectors for playback and tape monitoring. Connect the left and right `Audio Input' of the tape machine to the TAPE 1 OUT connectors for recording. 9. PRE OUT, MAIN IN Connections to an external pre-amplifier, power amplifier or processor, such as a surround-sound decoder. In normal use these should be connected together using the links supplied. To connect your NAD-712 to external processor or amplifier sections first remove these links. Use a twin phono-to-phono GB lead to connect to the left and right `Audio Input' of the Power amp or processor to the Pre Out connectors. Connect the left and right `Audio Output' of the Preamp or processor to the Main In connectors. Note: The Pre-Out output signal will be affected by the NAD-712's volume and tone control settings. very loud sounds. This is caused by the amplifier cutting off or `hard clipping' the peaks of sound that it 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. 10. NAD-LINK IN, OUT The NAD-Link connector is used to pass commands from the remote control to and from other units fitted with NAD-Link connectors. This allows centralised c ...
