UNPACKING AND SETUP what’S in the box

Packed with your C 375BEE you will find:

The SR 8 remote control with 2 (two) AA batteries

This owner’s manual

A detachable AC power cord.

Save the packaging

Please save the box and all of the packaging in which your C 375BEE arrived. Should you move or otherwise need to transport your C 375BEE, this is by far the safest container in which to do so. We’ve seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that box!

chooSing a location

Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide a clear line of sight, within

23 feet/7 meters, between the C 375BEE’s front panel and your primary listening/viewing position. This will ensure reliable infrared remote control communications. The C 375BEE generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the C 375BEE atop other components, but the reverse usually should be avoided.

It is especially important that sufficient ventilation be provided. If you are contemplating locating the C 375BEE within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow.

noteS on inStallation

Your NAD C 375BEE 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 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 C 375BEE are colour coded for convenience.

Red and white are Right and Left audio respectively.

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 C 375BEE, 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.

BARE WIRES AND PIN CONNECTORS warning:

The terminals marked with this symbol are hazardous live. External wiring connected to these terminals requires installation by an instructed person or the use of ready-made leads or cords.

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.

Always turn the C 375BEE and associated external power amplifiers OFF before connecting or disconnecting anything to the MAIN IN sockets.

10 pre out 2:

Connections to an external power amplifier or processor, such as a surround-sound decoder. In normal use, this should be connected to the Main In sockets with the links supplied. To connect your NAD C 375BEE to external processor or amplifier sections, remove first these links. Use a twin RCA-to-RCA lead to connect the left and right “Audio Input” of a power amplifier or processor to the PRE OUT 2 sockets.

Always turn the C 375BEE and associated external power amplifiers OFF before connecting or disconnecting anything to the PRE OUT 2 sockets.

The PRE OUT 2 output signal will be affected by the C 375BEE’s volume and tone control settings.

11 volume pre out 2:

The VOLUME PRE-OUT 2 control allows for adjustment of the output level of the PRE OUT 2 sockets. Turn clockwise to increase the PRE OUT 2 volume setting; counter clockwise to lower it. When set to the maximum position, the output level will be identical to that of the PRE OUT 1 sockets. Refer also to the item below about

“Bi-Amping”.

bi-amping

Some loudspeakers have separate connection terminals for the LF (Low

Frequency) and HF (High Frequency) sections of the speaker. This facility allows to “Bi-Amp” these speakers, where a separate power amplifier is used for the LF and HF section, which may improve overall sound quality.

The C 375BEE provides two sets of preamplifier outputs (PRE OUT 1 and

PRE OUT 2) to facilitate the connections for Bi-Amping. Moreover, the level from PRE OUT 2 can be reduced in relation to PRE OUT 1 to accommodate power amplifiers with different gain (amplification factor).

To set up the C 375BEE with power amplifiers first decide which power amplifier has the highest gain. This is easily done by comparing the loudness level of the power amplifiers in an identical system (keep the volume control at the same level; use the same source and speakers).The amplifier that plays louder has the highest gain (note that this does not need to be the more powerful amplifier of the two). Connect the amplifier with highest gain to the PRE OUT 2 sockets; the other power amplifier to the PRE OUT 1 sockets. From the maximum level position, use the VOLUME

PRE OUT 2 control to reduce the output level of PRE OUT 2 so that the volume level of both power amplifiers is exactly matched.

12 bridge mode:

The C 375BEE amplifier can be configured to be

MONO (Bridge Mode), more than doubling its output power. This way, the C 375BEE can be used as part of a high power stereo or hometheatre system, by connecting additional power amplifiers.

In BRIDGED MODE (switch at ON setting), the C 375BEE will produce approximately 330W into an 8 ohm loudspeaker. In this mode, the amplifier sections will react as though the speaker impedance has been halved. Low impedance speakers (under 8 ohms) are not recommended when using Bridge Mode as these may cause the amplifier’s thermal cut-out to operate if played at high levels.

Set the BRIDGE MODE switch to the “ON” position and connect the speaker to the terminals marked “L +” and “R+” ensuring that the “L+” is connected to the “+” terminal of your loudspeaker and the “R+” is connected to the loudspeaker’s “ - ” terminal. Connect the source to the Left INPUT sockets.

The BRIDGE MODE indicator on the front panel will illuminate when the

C 375BEE is in Bridge mode. Return normal speaker connections (Refer also to the item below about “SPEAKERS A,B”). and keep BRIDGE MODE switch to “OFF” position for normal stereo listening.

NOTE

Do not connect anything to the Right Input socket when Bridge Mode is selected.

13 Soft clipping™:

Enables NAD’s proprietary Soft Clipping circuitry on all channels. At [ON] position, Soft Clipping gently limits the output of the C 375BEE to minimize audible distortion should the amplifier be over-driven. Soft Clipping may simply be left ON at all times to reduce the likelihood of audible distortion from excessive volume settings.

However, for critical listening and to preserve optimum dynamics, you may wish to defeat it by setting this switch to “OFF” position.

The SOFT CLIPPING indicator on the front panel will illuminate when the C 375BEE is in Soft Clipping mode. See also below the item about

“POWERDRIVE”.

The C 375BEE uses NAD’s proprietary PowerDrive™ amplifier technology for all channels to preserve accurate, linear reproduction regardless of the loudspeaker. This uniquely efficient power-supply topology provides the real-world benefits of high dynamic power that remains uncompromised by low-impedance speakers.

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. PowerDrive offers greater amplifier stability and low impedance drive capability, resulting in less distortion when driving real speakers with real program material.

IDENTIFICATION OF CONTROLS

14 ir in/out:

These mini-jacks accept and output remote-controlled codes in electrical format, using industry-standard protocols, for use with “IR-repeater” and multi-room systems and related technologies.

ir in:

This input is connected to the output of an IR (infrared) repeater

(Xantech or similar) or the IR output of another component to allow control of the C 375BEE from a remote location.

ir out:

When connected to the IR IN of an ancillary equipment, direct the ancillary equipment’s own remote control to the C 375BEE’s infrared receiver to command or control the linked unit.

All NAD products with IR IN/IR OUT features are fully compatible with the C 375BEE. For non-NAD models, please check with your other product’s service specialists as to their compatibility with the C 375BEE’s

IR features.

15 +12v trigger out:

The +12V TRIGGER OUT is used for controlling external equipment that is equipped with a +12V trigger input. This output will be 12V when the C 375BEE is ON and 0V when the unit is either OFF or in standby. This output can drive a load up to 50mA at 12V.

16 rS-232:

Connect this interface via RS-232 serial cable (not supplied) to any

Windows® compatible PC to allow remote control of the C 375BEE through

NAD’s proprietary PC software or other compatible external controllers.

NAD is a certified partner of AMX and Crestron and fully supports these external devices. See your NAD audio specialist for more information.

RCA lead from your turntable to this input if you are using a Moving

Coil cartridge.

18 mc-mm Switch:

Slide this switch to either MM (Moving Magnet) or

MC (Moving Coil) depending upon the phono cartridge being used.

19 phono ground connector:

Turntables normally includes a single wire earth lead. Use the C 375BEE phono ground connector to connect this lead. Unscrew the terminal to expose the hole, which will accept the lead. After insertion, tighten the terminal to secure the lead.

20 mm input:

Input for a Moving Magnet phono cartridge. Connect the twin RCA lead from your turntable to this input if you are using a

Moving Magnet cartridge.

21 SpeakerS a, b:

The C 375BEE is equipped with two sets of speaker connectors. Use the Speakers A terminals for the “main” speakers and use the Speakers B terminals for a second pair, for example, extension speakers located in another room.

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.

In Bridge Mode, connect the single speaker to the terminals marked

“R +” and “L+” ensuring that the “L+” is connected to the “+” terminal on your loudspeaker and the “R+” is connected to the loudspeaker’s “-” terminal. Refer also to the section above about “BRIDGE MODE”.

Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire to connect loudspeakers to your C 375BEE. 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.

22 ac mainS input:

The C 375BEE 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 C 375BEE’s AC Mains input socket first. Connect only to the prescribed AC Outlet, i.e., 120V 60 Hz or 230V 50 Hz. Always disconnect the AC Mains cable plug from the live wall socket first, before disconnecting the cable from the C 375BEE’s Mains input socket.

23 power Switch:

The POWER switch supplies the master AC mains power for the C 375BEE. When this switch is at ON position, the

C 375BEE is in standby mode as shown by the amber status condition of the standby LED. Toggle the front panel’s STANDBY button to switch

ON the C 375BEE or back to standby mode. If you intend not to use the

C 375BEE for long periods of time (such as when on vacation), switch the POWER switch to the OFF position. When the POWER switch is at

OFF position, the front panel power button or SR 8 remote control cannot activate the C 375BEE.

24 Switched ac outlet (120v version only):

This convenience outlet can supply switched power to another component or accessory. With the Power switch at the rear panel set to ON position, this outlet is powered ON or OFF by the front panel STANDBY switch or by the SR 8’s

[ON/OFF] buttons. The total draw of all devices connected to this outlet must not exceed 100 watts.

25 fuSe holder:

In the unlikely event a fuse may need to be replaced, unplug the AC cord from the wall. Then, remove all connections from the amplifier. Use a flathead screw driver or similar to open the fuse holder via the slot indicated. With the screw driver in place, push and turn counterclockwise to open the fuse holder. Only replace the fuse with the same type, size, and specification – T10AL 250V for 120V version or T5AL 250V for 230V version.

IMPORTANT NOTICE

Do not use any substitute fuses of different types or with different ratings or values. Failure to observe this precaution may cause damage to the amplifier circuits and may create a fire hazard and/or defeat the safety built into the C 375BEE and may void the warranty.
