Please make sure that the C 275BEE is powered OFF or unplugged before making any connections. is also advisable to power-down or unplug all associated components while making or breaking any signal or AC power connections. 1 INPUT SELECT: Slide this switch to either‘FIX"or"VAR! When it is Bi-Amping set to FIX, the input signal is taken straight to the power amplifier Some loudspeakers have separate connection terminals for their LF circuitry. This setting is normally used in a system with only one power {Low Frequency) and HF (High Frequency) sections. Where a separate amplifier or multiple but identical power amplifiers. power amplifier is used for the LF and HF section, this facility allows to *Bi-Amp'such speakers which may improve overall sound quality. When When the INPUT SELECT switch is set to"VAR" (Variable) it is possible Bi-Amping with different models of power amplifiers, it is likely to occur to adjust the volume level for both channels simultaneously, using the that one power amplifier has more “gain” than the other, resulting in a INPUT LEVEL CONTROL. This can be useful for: mismatch in level for the woofer and tweeter ofthe speaker. Adjust the level control so that woofer and tweeter are in perfect balance with Level Matching each other (identical gain of power amplifiers). In a surround sound or system with more than one set of speakers, differences in levels can occur due to variance inefficiencies between NOTES these speakers. In case your preamplifier or processor also has + Alwaystum OFFtheC275BEE andother components in the system before individual trims for each channel, set these to neutral or mid position connecting or disconnecting anything to the INPUT sockets. {usually marked as OdB). Adjust the INPUT LEVEL CONTROL so that When the INPUT SELECT switch is set to "VAR" for the first time, it is the speakers driven by the C 275BEE have the correct volume level advised that the “INPUT LEVEL CONTROL" level ofthe C 275BEE or the compared to the other speakers, judging from your listening position. volume control level of your preamplifier/processor be set to their minimum settings.

REAR PANEL 4 BRIDGE MODE: The C 275BEE amplifier can be configured to be MONO (Bridge Mode), more than doubling its output power. This way, the C 275BEE can be used as part of a high power stereo or home- theatre system, by connecting additional power amplifier. In BRIDGED MODE, the C 275BEE 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 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” +”and'R+'ensuring that the"L+" is connected to the “+” terminal of your loudspeaker and the*R+'is connected to the loudspeaker * "terminal. Connect the source to the INPUT sockets. The BRIDGE MODE indicator on the front panel will illuminate when the C2758EE is in Bridge mode. NOTE Do not connect anything to the Right Input socket when Bridge Mode is selected. 5 SOFT CLIPPING": Enables NADS proprietary Soft Clipping circuitry on all channels. At [ON] position, Soft Clipping gentiy limits the output ofthe C 275BEE 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 willilluminate when the amplifier sin Soft Clipping mode. 6 +12VTRIGGER IN/INPUT SENSE - OFF/AUTO: This dual function sitch alternates between sensing a +12V input as applied through the +12V trigger IN jack (item 7 below) or sensing any input signal applied atthe INPUT sockets. ATAUTO setting and with the +12V trigger input ofthe C 275BEE connected to the DC output jack of a compatible auxliary component, the C 275BEE can be switched remotely from standby mode to ON and vice-versa. Use a 3.5mm mini-jackto pass +12V from the auxiliary equipment into the C 275BÈE. IFthere is no 3.5mm minijackinserted atthe +12 Trigger IN jackand with the switch still at AUTO setting, the C 275BE€ willinstantaneously turn ON fiom standby state fit senses any input signal (approximately above 20m RS input) applied through the INPUT sockets. In the absence of a +12V trigger input or any input signal at the INPUT. sockets and with OFF/AUTO switch set to AUTO, the C 2758ÈE wi sitch automatically to standby mode. Slide the OFF/AUTO switch to OFF setting for the C 27SBEE to be normally switched ON (or back to standby mode) using the front panel STANDBY button NOTES = Switch the rear panel POWER switch to ON position in order to make use ofthe +12V Trigger IN or Input Sense AUTO feature as well as the front panel STANDBY button. Atinput sense mode itwilltake about 10 minutes for the C 275BEE to go to standby mode when the input signal source is turned OFF or go below 20 mv. IMPORTANT NOTICE With the rear panel POWER switch at ON position and the OFF/AUTO switch at AUTO setting, the C 275BEE cannot be switched ON using the front panel STANDBY button. Slide the OFF/AUTO switch to OFF setting for the C 275BEE to be normally switched ON (or back to standby mode) using the front panel STANDBY button. 7 +12VTRIGGER INPUT: The +12V Trigger input allows the C 275BÈE to be suitched remotely from standby mode to ON and vice-versa by ancillary equipments such as à preamplifier, AV processor etc. The controlling device must be equipped with à 12V trigger output to use this feature. Refer also to the section above about “+12V TRIGGER IN/INPUT SENSE - OFF/AUTO". 8 FUSEHOLDER: 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 - TIOAL 250V for 120V version orTSAL 250V for 230V version IMPORTANT NOTICE Do not use any substitute fuses of different types or with different ratings orvalues. Failure to observe this precaution may cause damage to the amplifier circuits and may create a fire hazard and/or defeat the safety buil into the amplifier and may void the warranty. 9 SPEAKERS A, B: The C 275BE€ 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 thatthe"R"is connected to the"+'terminal on your loudspeaker and the “Ris connected to the loudspeaker$ "terminal. Connect the terminals marked'L+"and'Lto the left speaker inthe 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 loudspeakers *" 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 NAD C 275B£E. 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 10 AC MAINS INPUT: The C 275BEE comes supplied with a separate AC Mains cable. Before connecting the cable to a live wall socket ensure thatitis firmly connected to the C 275BEES AC Mains input socket fist. Connect onfy ta the prescribed AC Outlet, ie, 120V 60 Hz or 230V 50 Hz. Always disconnect the AC Mains cable plug from the live wall socket fist, before disconnecting the cable from the C 275BEES Mains input socket. POWER SWITCH: The POWER switch supplies the master AC mains power for the C 275BEE. Refer to the ATO LOGIC chart below for a better understanding ofthe role ofthe POWER switch when switching ON or OFF the C 275BEE. If you intend not to use the C 275BEE for long periods of time (such as when on vacation), switch the POWER switch to the OFF position.

AUTOMATED TURN-ON LOGIC (ATO LOGIC) The C 275BEE may be turned ON in any one of three discrete ways for complete system flexibility - from the front panel standby button, the 12V- TRIGGER circuit or by the input signal-sensing circuit. The ON/OFF power control is managed by the Automated Turn-On logic or ATO Logic circuit that requires the C 275BEE to be switched back to standby mode in

(using 3.5mm mini-jack plug) Mini jack unplugged INPUT SENSE Input signal >20mV Input signal +1V ov Lea (blue) SISISIS NOTE Ifthe +12V TRIGGER IN/INPUT SENSE switch is set to OFF, the presence or absence of +12V trigger input or any input signal at the INPUT sockets will not have any effect on the C 275BEE, effectively defeating both features. POWERDRIVE The C 275BEE uses NAD' proprietary PowerDrive" amplifier technology for ll channels to preserve accurate, linear reproduction regardless ofthe 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
