Mute Setup; Eq Setup - Classe Audio Sigma SSP Owner's Manual

Mute Setup

The Mute Setup page allows you to choose how the Mute button functions. The
options for mute control are:
• specific - allows you to select the exact value to which the volume is
attenuated. If the current volume is already below that level when muting
is engaged, the volume remains unchanged. The factory default is - - -,
which is fully muted.
• dampening - reduces the current listening level by a specified amount (e.g.
-25.0 dB).

EQ Setup

The Sigma SSP's Parametric EQ capability allows you to build very precise
digital audio filters to help compensate for fixed sonic irregularities defined
by the location and characteristics of your speakers, your room and your
listening position in the room. These filters should be constructed based
upon audio measurements made by a well-qualified acoustical engineer. These
powerful filters are made available in a completely manual fashion to help your
professional installer give you the best listening experience possible.
As many as nine filters can be built for each speaker channel. An Aux channel
used in bi-amp mode assumes the same filters as defined for its Left or Right
channel partner.
In order to define the PEQ filters, select EQ Setup from the System Setup
menu, Check the box to enable the EQ. Choose which channel you wish to
adjust, select a band and enable its filter, then tune it with the appropriate center
frequency, gain, and Q.
