control is also available directly by pressing the front panel
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.
Feed the sound from the processor into the
