The Sigma SSP has two auxiliary channels that can be utilized for bi-amping
the L&R speakers, adding Rear channels, adding Height channels for the Dolby
PLIIz mode or providing a two-channel down-mix for an analog recorder or
another system.
If the Aux channel outputs are enabled in bi-amp mode, (technically, this is
called power-biamping), you will be using separate amplifier channels for the
high and low frequency drivers of your loudspeaker, but the passive crossovers in
the speaker will do the work of filtering low and high frequency signals. In this
mode, the two auxiliary channels produce the same output as the Front Left and
Right channels.
NOTE: When bi-amping the Aux channel output levels may be
trimmed up or down relative to the Front L&R outputs in order
to account for amplifiers with different gain. This will be necessary
to get the respective high- and low-frequency speakers to produce
the correct, matching output levels. Note that using the balanced
output for Front L&R will require a +6 dB adjustment of the
Aux channels to match output levels for high- and low-frequency
amps having the same gain. All Classé Sigma, Delta and CT series
amplifiers have the same gain and may be used in any combination
for bi-amping.
When used for two-channel down-mix, the Aux channels may be configured for
either fixed or variable output. If variable is selected, the output level tacks with
the Front L&R channel volume.
The Display Setup menu page, shown below, allows you to configure the
brightness and display timeout used for the touchscreen display.
The Brightness setting of the Sigma SSP touchscreen has three possible values:
low, medium, and high. Select the setting you prefer. A high brightness setting
usually works best in brightly-lit rooms; you may find that a lower setting is less
visually intrusive under more subdued lighting conditions.
