Vol Res

There are three volume-display options to chose from: 'Std' , 'Fine' or 'Ref' . Standard and

Fine represent different levels of volume-control sensitivity; the Reference setting gives

absolute increments in 0.5dB steps.

I/P Trims

Input trims are used to compensate for variations in output levels of different source

equipment. If, for example, your CD player is louder at a given volume display value

than other inputs, you can attenuate it by using this setting so that it matches your other

components.

Use the source-select buttons to select the input you wish to adjust, then the control knob

to set (increase or decrease) the input volume for that source.

Proc Mode

Processor mode enables you to fix the gain (volume setting) of your A28. The A28 (in

combination with a power amp.) can then be used to drive the front left and right speakers

of a surround-sound system, when fed from a separate processor. The volume of the entire

system can then be controlled using the processor.
