Main Channel
The Dual Input Mixer can be enabled or configured in a pass-through mode (Main
channel will be passed through without any mixing). When enabled, the volume of
the main and mix channels can be independently controlled before they are mixed
together.
The volume range allowed on each channel is 0% to 200% of the incoming signal
level. The default is 100% (same as input signal level) volume on the main input
and 0% (muted) on the mix input.
Please refer to section 6.2.4.1 for programming examples on how to enable/disable
the mixer and also to set the main and mix channel volume.
SigmaTel Surround
SigmaTel Surround is a royalty free virtual surround algorithm for stereo or mono
inputs. It widens and deepens sound stage for music input.
The SGTL Surround can be enabled or configured in pass-through mode (input will
be passed through without any processing). When enabling the Surround, mono or
stereo input type must be selected based on the input signal. Surround width may
be adjusted for the size of the sound stage.
