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 1 OUT sockets for recording.

8. SPEAKERS

Speaker terminals for speakers with an impedance of 4 ohms or more. Connect the right speaker to the terminals marked '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 C300. 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.

9. 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.

FRONT PANEL CONTROLS

1. POWER

Pressing the POWER switch turns the unit On. The LED will light up red initially and within seconds will turn green. Pressing the POWER switch again will turn the amplifier Off.

2. POWER/PROTECTION LED

Upon switching Power on, the LED will light up red for a few seconds before the protection circuit is de-activated. The LED will then turn green and the amplifier is ready for normal operation. The LED will flash when the 'Mute' mode is selected (refer also to section "9. Volume" and the chapter "Remote control").

In cases of serious abuse of the amplifier, such as overheating, excessively low loudspeaker impedance, short circuit, etc. the amplifier will engage its Protection circuitry, indicated by the LED turning from green to red and the sound being muted. In such a case, turn the amplifier off, wait for it to cool down and/or check the speaker connections, making sure the overall loudspeaker impedance doesn't go below 4 ohms. Once the cause for the protection circuitry to engage has been removed, press Power again to resume normal operation.

3. 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.

4. BASS & TREBLE CONTROLS

The NAD C300 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.

5. TONE DEFEAT

The TONE DEFEAT switch by-passes the tone control section of the NAD C300. 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.

6. BALANCE

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.

7. 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.

8. INPUT SELECTORS

These buttons select the active input to the NAD C300 and the signal sent to the loudspeakers and the Tape outputs.

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.

TAPE 2 Selects Tape 2 as the active input.

TAPE 1 Monitor Selects the output from a tape recorder when playing back tapes or monitoring recordings being made through the Tape 1 sockets. Press the Tape 1 button once to select it and again to return to the normal input selection.

Tape 1 is a tape Monitor function which does not override the current input selection. For example, if the CD is the active input when TAPE 1 is selected, then the CD signal will continue to be selected and sent to both the TAPE 2, and TAPE 1 OUTPUT sockets, but it is the sound from recorder connected to Tape 1 that will be heard on the loudspeakers.

9. VOLUME

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.

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 Power/Protection LED flashing. Press MUTE again to restore sound. Mute does not affect recordings made using the Tape outputs.

TO MAKE A RECORDING

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

TAPE TO TAPE COPYING

You can copy between two tape machines connected to your NAD C300. Put the source tape in the recorder connected to Tape 2 and the blank tape into the recorder connected to Tape 1. By selecting TAPE 2 Input you can now record from Tape 2 to Tape 1 and monitor the signal coming from the original tape.
