Treble
The Treble control regulates the amount by which high frequency signals for all
speakers, except the subwoofer, are boosted or cut (see figure below).
Volume Output
This control sets the volume of the audio output through all channels, globally, to
either Variable (the default value) or Fixed.
Variable
When the Volume output is set to Variable, the volume can be attenuated using the
front panel knob, the SSP 7.1 Setup and Control Software, or SIS commands.
Fixed
The Fixed option sets the volume to the current attenuation level. Likewise, all
the Output Channel Trim levels (see page 4-6) are fixed at the values they had
immediately before the Volume Output was set to Fixed.
When "Fixed" is selected, the volume cannot be adjusted through the front panel
knob, by the SSP 7.1 Setup and Control Software, or by SIS commands.
