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
Output Trim on page 39) 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.
Equalization
Parametric equalization (or parametric “EQ”) allows the control of amplitude of each band,
center frequency (which can be shifted, widened, or narrowed) and bandwidth (which may
be labeled “Q” for Quality). Parametric equalization is used to improve the audio output in a
specific acoustic environment.
Resonance reduction — Reduces the level at specific frequencies that are too loud.
Speaker compensation — Compensates for peaks and dips in individual speaker output
response.
Tonal enhancement — Increases the level of frequencies within a broad or narrow range
that sound too quiet.
