1. Connect the speakers to the rear Speaker sockets and sources to the relevant rear input sockets.
2. Plug in the AC power cord.
3. Press the POWER button to turn the NAD C350 on.
4. Press the required input selector.

NOTES ON INSTALLATION

Your NAD C350 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 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 C350 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 C350, 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 dampen the cloth with soapy water. Do not use solutions containing benzol or other volatile agents.

REAR PANEL CONNECTIONS (FIGURE 1)

1. 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 C350'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.

NOTES: It is advisable not to connect NAD-Link if these units that have their own built-in remote control command receiver and are positioned together, in direct view from the remote control handset. If you are unsure, try operating the products without NAD-Link first; If the unit responds to the remote control command, it will not be necessary to connect NAD-Link. Never loop the last unit back to the first NAD unit in the NAD-Link chain.

Unplug all units from the mains before connecting or disconnecting NAD-Link.

2. DISC INPUT

Input for additional line level input signals such as CD, Mini Disc player or the output signal from a step-up amplifier for a turntable. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio Outputs' to this input.

3. CD INPUT

Input for a CD or other line-level signal source. Use a twin RCA-to-RCA lead to connect the CD player's left and right 'Audio Outputs' to this input. The NAD C350 only accepts analogue signals from your CD player.

4. VIDEO INPUT

Input for the audio signal from a stereo VCR (or stereo TV/Satellite/Cable receiver) or other line-level audio source. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Out' of the unit to these inputs. Note: These are audio inputs only.

5. AUX INPUT

Input for additional line level input signals such as another CD player. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio Outputs' to this input.

6. TUNER INPUT

Input for a Tuner or other line-level signal source. Use a twin RCA-to-RCA lead to connect the Tuner left and right ‘Audio Outputs’ to this input.

7. TAPE 2 IN, OUT

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

8. TAPE 1 IN, OUT

Connections for analogue recording and playback to a secondary audio tape recorder of any type. 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.

9. PRE OUT 1

The NAD C350 allows for the connection multiple power amplifiers. If you are using a single stereo power amplifier, use the PRE OUT 1 sockets. If you are using a pair of power amplifiers specifically for Bi-amping, use the sockets to connect the power amplifier with the lowest gain of the pair. Use a twin RCA-to-RCA lead to connect to the left and right 'Audio Input' of the Power amp to the PRE OUT 1 sockets.

10. PRE OUT 2

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. 11) with the links supplied. To connect your NAD C350 to external processor or amplifier sections first remove these links. 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 2 sockets.

NOTE: The Pre-Out 2 output signal will be affected by the NAD C350's volume and tone control settings. Always turn the amplifier off before connecting or disconnecting anything to the Pre-Out 2 and Main-In sockets.

11. 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 2 sockets (No. 10) with the links supplied. To connect your NAD C350 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 to the Pre-Out and Main-In sockets.

12. 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 C350. 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.

13. 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 indicator on the front panel will illuminate when the amplifier is in Soft Clip mode.

14. 12V TRIGGER OUT

This output allows to remotely switch on or off ancillary equipment such as a tuner, power amplifier, etc. which are also equipped with a 12V trigger input. This can also be an AC outlet power strip equipped with a 12V trigger input. The 12V trigger output is activated whenever the unit is in switched to normal operational mode from Stand-by or Off.

For switching Stand-by/Power On of an external component through the C350, connect the 12V-trigger output of the C350 to the remote component's DC input jack. The plug required is a standard 3.5mm Mini-Jack plug ("mono"): The tip is the live or + connection, the shaft of the input jack is the 12V-trigger - or ground connection.

NOTES: Check the specifications of the Trigger input terminal on the other components to ensure these are compatible with the C350's 12V-trigger output. NAD components equipped with 12V input triggers are fully compatible with the C350's 12V output trigger.

The C350's 12V-trigger output voltage is 12V DC. The total maximum current must not exceed 200mA . Typically, NAD 12V input triggers draw less than 10mA of current.

Before making any connections to any 12V trigger input or output, make sure all components are disconnected from the AC mains.

Failure to observe the above may result in damage to the C350 or any ancillary components attached to it. If in doubt over the connections, installation and operation of the 12V trigger output consult your NAD dealer.

15. SWITCHED AC OUTLET (NORTH AMERICAN VERSIONS ONLY)

The AC power cord of another component may be plugged into this accessory outlet. Components plugged into this outlet will be switched On and Off by the POWER button on the front panel or by the ON and STAND-BY button on the remote control handset.

NOTE: The total power consumption of any components connected to the AC outlets may not exceed 100 Watts.

16. 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 (FIGURE 2)

1. POWER ON/OFF

Press the POWER button to switch the amplifier On. The Stand-by indicator (No. 2) over the power button will light up red and after a short pause will turn to green to indicate the amplifier is now ready for normal operation. Pressing the POWER switch again will turn the unit OFF completely, it will not respond to the remote control.

REMOTE CONTROL (FIGURE 3)

ON/OFF BUTTON (NO. 1)

When the amplifier is switched On, pressing the green On/Off button on the remote handset will put the NAD C350 into Standby mode and the Power indicator will turn amber. The amber Power indicator shows that power is being supplied to the NAD C350, but the system is currently in the Standby Mode. Press again to switch the amplifier On from Stand-by mode.

ON AND OFF BUTTONS (NO. 2)

Besides the On/Off toggle function of the green button (No. 1), the NAD C350 also has a separate On and Off button. This can be particularly useful to keep components within a system “in-sync”: This way all components will switch to stand-by when Off is pressed or switch to operating mode when On is pressed, instead of some components switching On when the amplifier is switched to Stand-by. (Note that the other components have to be capable of responding to the separate On and Off commands as well).

Press the ON button to switch the unit from Stand-by to the operating mode; The Stand-by indicator (No. 2) will turn from amber to green after a short pause and the indicator for the last selected source will light up. Press the OFF button to switch the unit to the Stand-by mode: The Stand-by indicator (fig. 1; No. 2) will light up amber.

NOTE: In Stand-by mode the C350 uses very little power. However, it is recommended that you switch the unit totally off if it is not going to be used for more than a couple of days. Switch off completely by pressing the POWER button on the front panel (No. 1), all lights will extinguish.

2. STAND-BY/PROTECTION INDICATOR

Upon switching Power on, the indicator will light up red and after a short pause turn to green to indicate the amplifier is ready for use.

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, the indicator will light up red and the sound will be 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, switch the amplifier On again.

The diagram below shows the operation of the Stand-by/protection indicator:

	Green	Amber	Red
Normal Operation	●
Stand-by		●
Protection			●

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. 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.

NOTES: When a command from the remote control is received, the Stand-by/protection indicator will blink. Note that the indicator may also blink when receiving commands not necessarily for the C350 but for other components in the system.

Direct sunlight, very bright or fluorescent ambient lighting may affect the operating range and angle for the remote control handset.

5. INPUT SELECTORS

These buttons select the active input to the NAD C350 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 indicators just above each button show 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 C350's tuner 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. Apart from the amber indicator to show Tape 1 is engaged, the green indicator for the active input will also stay lit.

NOTE: The remote control handset with the C350 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 C350. The Video 2 and Video 3 input selector buttons on the remote control handset are inoperative in the case of the C350.

6. SOFT CLIPPING INDICATOR

The green Soft Clipping indicator shows that the Soft Clipping mode is engaged. Refer also to chapter “Rear Panel Connections”, section 12; “Soft Clipping” for more information.

7. BASS & TREBLE CONTROLS

The NAD C350 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 a detent 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).

8. TONE DEFEAT

The TONE DEFEAT switch by-passes the tone control section of the NAD C350. 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.

9. 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 but will affect the signal going to the Pre-amp output (Pre Out).

10. 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 but will affect the signal going to the Pre-amp output (Pre Out).

REMOTE CONTROL (FIGURE 3)

Press the MUTE Button (No. 4) to temporarily switch off the sound to the speakers and headphones. Mute mode is indicated by the active input indicator 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).

Press the MASTER VOLUME UP and DOWN (No. 7) buttons to increase, respectively decrease the loudness level. Release the button when the desired level is reached.

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 C350. 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.
