WHAT'S IN THE BOX

Packed with your C 355BEE you will find:

• The SR 6 remote control with 2 (two) AAA batteries
• This owner's manual

SAVE THE PACKAGING

Please save the box and all of the packaging in which your C 355BEE arrived. Should you move or otherwise need to transport your receiver, 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 25 feet/8 meters, between the C 355BEE's front panel and your primary listening/viewing position. This will ensure reliable infrared remote control communications. The C 355BEE generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the C 355BEE on top of other components.

NOTES ON INSTALLATION

Your NAD C 355BEE 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 355BEE 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 355BEE, 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.

1 STANDBY BUTTON: The Standby Button turns ON and set to standby the C 355BEE. This button will only function when the Power/Standby/Protection LED is either amber representing the standby state, or green representing the ON state.
2 POWER/STANDBY/PROTECTION LED: Upon switching the power ON, the LED will light up red for a few seconds before the protection circuit is deactivated. The LED will then turn green, representing normal operation.

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 by the rear panel POWER button, 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 ON the rear POWER button and the Standby Button to resume normal operation.

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 SOFT CLIPPING INDICATOR: The green Soft Clipping LED shows that the Soft Clipping mode is engaged. Refer also to "IDENTIFICATION OF CONTROLS - REAR PANEL, item 14 Soft Clipping" for more information.
5 TONE DEFEAT: The TONE DEFEAT switch bypasses the tone control section of the NAD C 355BEE. 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 HEADPHONE SOCKET: A 1/4" stereo jack socket is supplied for headphone listening and will work with conventional headphones of any impedance. The headphone socket will work in parallel to the selected speakers. To listen to headphones only, de-select Speakers A and/or B.

NOTE

Always turn the amplifier off before connecting or disconnecting anything from to PRE OUT 1, 2 and MAIN IN sockets.

14 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 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™ LED on the front panel will illuminate when the amplifier is in Soft Clipping mode.
15 SPEAKERS A, B: The C 355BEE is equipped with two sets of speaker connectors. Use the Speakers A connectors for the 'main' speakers and use the Speakers B connectors 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.

Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire to connect loudspeakers to your NAD C 355BEE. 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.

16 SWITCHED AC OUTLET (North America version only): The SWITCHED AC OUTLET can supply switched power to another component or accessory. This convenience outlet can be switched ON or OFF using only the POWER switch located at the rear panel. The SWITCHED AC OUTLET cannot be switched ON or OFF using the front panel Standby button or the ON/OFF button of the remote control. The total draw of all devices connected to this Switched AC outlet must not exceed 120 watts.
17 IEC AC MAINS (POWER) INPUT: The C 355BEE 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 355BEE'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 355BEE Mains input socket.
18 POWER SWITCH: The POWER switch supplies the master AC mains power for the C 355BEE. When the switch is in the ON position the C 355BEE is in standby as shown by the amber Status Condition LED, above the Standby button on the front panel.

AUTO TUNE: In DAB mode, press this button to automatically scan all available local stations.

FM MUTE: In DAB mode, pressing this button will activate Dynamic Range Control, preset tune, manual tune, station order or other appropriate features. In FM mode, press this button to select the stereo or mono mode for FM tuning.

BLEND: The Blend button toggles between engaging and disengaging the Blend feature. The NAD Blend feature will allow you to reduce the amount of noise and hiss normally associated with received weak radio stations but still retain some level of stereo separation, instead of mono.

AM/FM/DAB: In tuner mode, toggle this button to switch to DAB, FM and AM frequency bands.

7 SLEEP: Press SLEEP to switch off the applicable tuner after a preset number of minutes. Each consecutive press will reduce the sleep time in preset increments until sleep mode is cancelled as could be shown in the front panel display.

8 TUNER/CD: The TUNER/CD switch applies relevant tuner controls when in the TUNER position, and applies CD controls to the appropriate buttons when in the CD position.

9 VOLUME: Press VOLUME ▲ or ▼ buttons to respectively increase or decrease the loudness level. Release the button when the desired level is reached. The motorised Volume control on the front panel will indicate the level set. The Volume buttons do not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp outputs.

10 MUTE: Press the MUTE Button to temporarily switch OFF the sound to the speakers and headphones. MUTE mode is indicated by the Power/Standby/Protection LED indicator on the front panel 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 Preamp outputs.

11 SPK A, SPK B: The SPK A and SPK B buttons engage or disengage the speakers connected respectively to the C 355BEE's Speakers A and Speakers B terminals. Toggle SPK A to switch ON or OFF the speakers connected to the speaker A terminals. Toggle SPK B to switch ON or OFF the speakers connected to the speaker B terminals. Press both buttons to engage both speakers.

12 DEV 1/DEV 2: The default setting for this SR 6 remote control is set to DEV 1. In this position, the Tuner/CD switch allows for both CD control and AM/FM Tuner functions. If one switches to DEV 2, the applicable buttons will remain for CD control buttons and now for dedicated AM/FM/DAB Tuner functions.
