ITALIANO PORTUGUÊS REAR PANEL CONNECTIONS (FIGURE 1)

The IR IN/OUT connector is used to pass commands from other units fitted with IR IN/OUT connectors. This allows centralized 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 IR IN/OUT to be controlled with the amplifier's remote control. To function with such other units, connect the C 352's IR OUT to the IR IN on the other unit. The IR connectors can be daisy-chained, IN to OUT, so that a whole system can be controlled from the remote control facilities of one unit. SVENSKA NOTES: It is advisable not to connect IR IN/OUT 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 IR IN/OUT first; If the unit responds to the remote control command, it will not be necessary to connect IR IN/OUT. Never loop the last unit back to the first NAD unit in the IR IN/OUT chain. Unplug all units from the mains before connecting or disconnecting IR IN/OUT.

If you are using a single, external stereo power amplifier, disconnect the links to the Main-In sockets. The C 352's internal power amplifier is now disconnected. Use a twin RCAto-RCA lead to connect to the left and right ‘Audio Input’ of the Power amp to the PRE OUT 1 sockets.

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 C 352 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 C 352’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.

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.

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 Clipping On. The Soft Clipping™ indicator on the front panel will illuminate when the amplifier is in Soft Clipping mode.

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 switched to normal operational mode from Stand-by or Off.

15. IEC AC MAINS (POWER) INPUT

The C 352 comes supplied with a separate AC Mains cable. Before connecting the cable to a live wall socket ensure that it is firmly connected to the NAD C 352's AC Mains input socket first. Always disconnect the AC Mains cable plug from the live wall socket first, before disconnecting the cable from the C 352 Mains input socket.

(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.

REMOTE CONTROL ON /OFF (FIGURE 3) 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 red, then 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. 2; No. 2) will light up amber. NOTE: In Stand-by mode the C 352 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. For switching Stand-by/Power On of an external component through the C 352, connect the12V-trigger output of the C 352 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.

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 C 352. The highcurrent 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. Failure to observe the above may result in damage to the C 352 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. DEUTSCH NOTE: always turn the amplifier off before connecting or disconnecting anything to the Pre-Out and Main-In sockets. NOTES: Check the specifications of the Trigger input terminal on the other components to ensure these are compatible with the C 352's 12Vtrigger output. NAD components equipped with 12V input triggers are fully compatible with the C 352's 12V output trigger. The C 352's 12Vtrigger output voltage is 12V DC. The total maximum current must not exceed 100mA. 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. ESPAÑOL

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.

2. POWER / STAND-BY / PROTECTION INDICATOR

Upon switching Power on, the indicator will light up amber in standby state. While one of the input select buttons is pressed, the LED will turn red for a moment, then turn green for ON state. 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. FRANÇAIS The diagram below shows the operation of the Stand-by / protection indicator: Normal Operation Stand-by Protection Green

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 counter-clockwise) before connecting or disconnecting headphones. Listening at high levels can damage your hearing. ITALIANO

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. PORTUGUÊS 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 C 352 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.

These buttons select the active input to the NAD C 352 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. 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 C 352 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 C 352. The Video 2 and Video 3 input selector buttons on the remote control handset are inoperative in the case of the C 352.

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.

The NAD C 352 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).

The TONE DEFEAT switch bypasses the tone control section of the NAD C 352. 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.

POWERDRIVE To meet the diverse requirements of high current drive and high dynamic power, our patented PowerDrive amplifier circuit will build further on our reputation for amazingly effective power. By adding a second high-voltage rail to our well regulated high-current power supply, we get an "overdrive" that can nearly double the continuous power on a short term dynamic power basis. This is a further development and refinement of our renowned Power Envelope circuit, utilized by NAD in the 80's and 90's. PowerDrive differs from Power Envelope in that it offers greater amplifier stability and low impedance drive capability, resulting in less distortion when driving real speakers with real program material. 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 C 352. 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. REMOTE CONTROL HANDSET (FIGURE 3) The Remote Control handset handles all the key functions of the NAD C 352 and has additional controls to remotely operate NAD Tuners, Cassette and CD machines.

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 Preamp output (Pre Out). DEUTSCH 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).

POWER ON AND OFF BUTTONS

The NAD C 352 remote 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 (Fig. 2; No. 2) will turn from amber, to red, then to green and the indicator for the last selected input will blink and light up. Press the OFF button to switch the unit to the Stand-by mode: The Stand-by indicator will light up amber. ESPAÑOL

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.
