Balance – Once selected, use the Control knob to shift the balance between Left and Right channels.

Volume Resolution – RES REF, RES FINE or RES STD. ‘Fine’ and ‘Standard’ represent different levels of volume control sensitivity. The ‘Reference’ setting gives absolute increments in 0.5dB steps.

Input Trims – use the source select buttons and Control knob to set input trims for each source. Input trims are used to compensate for variations in output levels of different source equipment.

Processor Mode – This mode enables you to adjust the gain of the amplifier. The amplifier can then be used to drive the front left and right speakers in a surround sound system when fed from a separate processor. You can then control the volume of the entire system using the processor, feeding the sound into the TAPE input. Set the gain to match the amplifiers that drive your other loudspeakers.

Recording Output – This allows you to select the source signal for recording: AV, PHONO, CD, TUNER, AUX or DVD.

Maximum ‘On’ Volume – Use the Control knob to adjust the volume setting at switch-on. ONVOL OFF indicates that the feature is not activated. ONVOL 1 (or higher) sets the volume

at start-up (in dB).

Reset – this restores all amplifier settings, including input trims, to their factory defaults.
