NAD Official Manual for the C340 Stereo Amplifier: Features, Setup, and Connections

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. AC LINE CORD

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.

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- of-sight 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.

4. INPUT SELECTORS

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.

FRONT PANEL CONTROLS

TAPE 1 Selects Tape 1 as the active input.

1. POWER

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.

2. HEADPHONE SOCKET

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.

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).
