OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner- preamplifier, 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. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 - 1.83 m) apart. Mount antenna discharge unit as close as possible to where lead- in enters house. 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).

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.

Using twin RCA-t0-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.

Connections for analogue recording and playback to a secondary audio tape recorder of any type. Using twin RCA-t0-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.

Connections to an external power amplifier or processor, such as a surround-sound decoder. In normal use these should be connected to the Main-In sockets (No. 9) with the links supplied. To connect your NAD C340 to external processor or amplifier sections first remove these links. Use a twin RCA-t0-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.

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-10-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.

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 Of. 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.

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.

Plug the AC power cord into a live AC wall socket. Make sure all connections have been made before connecting to mains.

13. 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 tuner, CD player or cassette-deck) also equipped with NAD-Link to be controlled with the amplifier’s remote control. To function with such other units, connect the C340'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.

Pressing the POWER switch turns the unit On. The LED for the last selected input will light up. Pressing the POWER switch again will turn the amplifier Off. NOTE: The remote control handset supplied with the C340 is of a universal NAD type, designed to operate several NAD models. Some buttons on this handset are inoperative as the functions aren't supported by the C340. The Green On/Off button on the remote control handset is inoperative in the case of the C340.

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.

3. 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- ofssight 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.

These buttons select the active input to the NAD C340 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 C340'S tuner input. TAPE 2 Monitor Selects the output from a tape recorder when playing back tapes or monitoring recordings being made through the Tape 2 sockets. Press the Tape 2 button once to select it and again to return to the normal input selection. Tape 2 is a tape Monitor function which does not override the current input selection. For example, if the CD is the active input when TAPE 2 is selected, then the CD signal will continue to be selected and sent to both the TAPE 1, and TAPE 2 OUTPUT sockets, but it is the sound from recorder connected to Tape 2 that will be heard on the loudspeakers. Apart from the amber LED to indicate Tape 2 is engaged, the green LED for the active input will also stay lit. TAPE 1 Selects Tape 1 as the active input. NOTE: The remote control handset with the C340 supplied is of a universal NAD type, designed to operate several NAD models. Some buttons on this handset are inoperative as the functions aren't supported by the C340. The Video 2 and Video 3 input selector buttons on the remote control handset are inoperative in the case of the C340.

5. SOFT CLIPPING INDCATOR

The green Soft Clipping LED shows that the Soft Clipping mode is engaged. Refer also to chapter “Rear Panel Connections”, section 10; “Soft Clipping” for more information.

6. BASS & TREBLE CONTROLS

The NAD C340 is fitted with BASS and TREBLE tone controls to adjust the tonal balance of your system. The 12 o'clock position is ‘flat with no boost or cut, and an indent indicates this position. Rotate the control clockwise to increase the amount of Bass or Treble. Rotate the control anti-clockwise to decrease the amount of Bass or Treble. The Tone controls do not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

The TONE DEFEAT switch by-passes the tone control section of the NAD C340. If the Tone Controls are not normally used and left in the 12 o’clock position, then it is advisable to switch out the Tone Control section altogether by using this switch. In the ‘out’ position, the Tone Control circuits are active, pushing the TONE DEFEAT switch ‘in’ bypasses the Tone Control section.

The BALANCE control adjusts the relative levels of the left and right speakers. The 12 o’clock position provides equal level to the left and right channels. A detent indicates this position. Rotating the control clockwise moves the balance towards the right. Rotating the control anti-clockwise moves the balance to the left. The BALANCE control does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

The VOLUME control adjusts the overall loudness of the signals being fed to the loudspeakers. It is motor driven and can be adjusted from the remote control handset. The VOLUME control does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out) On the remote control handset, press the MUTE Button to temporarily switch off the sound to the speakers and headphones. Mute mode is indicated by the active input LED flashing. Press MUTE again to restore sound. Mute does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

When any source is selected, its signal is also fed directly to any tape machine connected to the TAPE 1 or TAPE 2 OUTPUTS for recording.

TAPE TO TAPE COPYING

You can copy between two tape machines connected to your NAD C340. Put the source tape in the recorder connected to Tape 1 and the blank tape into the recorder connected to Tape 2. By selecting TAPE 1 Input you can now record from Tape 1 to Tape 2 and monitor the signal coming from the original tape.
