VOLUME PRE OUT 2: The VOLUME PRE-OUT 2 control allows for adjustment ofthe 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 ofthe PRE OUT 1 sockets. Refer also to the item below about “B-Amping' BI-AMPING Some loudspeakers have separate connection terminals for the LF (Lowr Frequency) and HF (High Frequency) sections of the speaker This facility allons to"B-Amp' these speakers, where à separate power amplifier is used for the LF and HF section, which may improve overall sound quality. The C 375BEE provides to sets of preamplifier autputs (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 accommodite power ampliiers with different gain (amplification factor) To set upthe C 375BEE with power amplfers first decide which power amplifier has the highest gain. This is easy done by comparing the loudness level ofthe por amplifirs 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 ofthe two). Connect the amplifier with highest gain to the PRE OUT 2 sockets:the other pouver 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 amplfiersis exactly matched. REAR PANEL 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 home- theatre 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 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 C375BEE is in Bridge mode. Return normal speaker connections (Refer also to the item below about "SPEAKERS AB). 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 NADS proprietary Soft Clipping circuitry on all channels. At [ON position, Soft Clipping gently limits the output ofthe C 375BÈE 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" POWERDRIVE The C 375BEE uses NADS proprietary PowerDrive" amplifier technology for al channels to reserve accurate, linear reproduction regardes ofthe loudspeaker This uniquely efficient power-supply topology provides the realkworld benefits of high dynamic power that remains uncompromised by lon-impedance speakers.
