If an indoor antenna is used (either built into the set or installed separately), never allow any part of the antenna to touch the metal parts of other electrical appliances such as a lamp, TV set etc. ATTENTION CAUTION CAUTION POWER LINES Any outdoor antenna must be located away from all power lines. OUTDOOR ANTENNA GROUNDING If an outside antenna is connected to your tuner or tunerpreamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements for the grounding electrode. a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger, as a ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 - 1.83 m) apart. c. Mount antenna discharge unit as close as possible to where leadin enters house. d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. see NEC Section 810-21 (j). EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND TELEVISION EQUIPMENT. NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer's attention to Article 820-22 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the ground cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

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 is switched off before making any connections. The RCA sockets on your NAD C340 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 C340, 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 userserviceable 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.

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 C340's volume and tone control settings, always turn the amplifier off before connecting or disconnecting anything from to Pre-Out and Main-In sockets. 9. 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. 8) with the links supplied. To connect your NAD C340 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. 10. 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 it 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 Clip On. The Soft Clipping LED on the front panel will illuminate when the amplifier is in Soft Clip mode. GB 4 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 C340. 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.
