Tone Control – Global or Per source. This
species the scope of changes for ‘Bass’ and
‘Treble’ tone settings. The default setting is ‘Global’
which affects all inputs equally. ‘Per source’ allows
you to set tone controls for individual inputs: once
set, the amplier remembers tone settings for
each input.
Processor Mode – This mode enables you to
adjust the gain of the amplier. The amplier
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 ampliers that drive your
other loudspeakers.
Volume Resolution – Standard, fine or
Reference. ‘Standard’ and ‘Fine’ represent
different levels of volume control sensitivity. The
‘Reference’ setting gives absolute increments in
0.5dB steps.
Volume display mode – graphic or numeric
shows the volume either as a bar graph or as a
number. If Volume resolution is set to ‘Reference’
a numeric volume display shows the actual decibel
gure.
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.
