STV82x7
Dedicated Digital Signal Processor (DSP)
4.6.5
Bass Management Configuration 4
This configuration implements the Simplified Dolby configuration. The center, left surround and right
surround channels are summed and then filtered by the LPF. The composite bass information is
either summed back into the left and right channels or summed with the LFE channel and sent to
the subwoofer output, see
Figure 17
.

SRS WOW and TruSurround XT
The SRS
TruSurround XT
is a processing system that can accept from 1 to 6 channels on input
and that will generate a 2-channel output signal.
This processing system includes the latest SRS
algorithms:

4.7.1
SRS TruSurround
The SRS
TruSurround
is a processing that can accept from 2 to 5 channels on input and that will
generate a 2-channel output signal.
SRS
TruSurround
uses Head-Related Transfer Function (HRTF) -based frequency tailoring of
(L/R) difference signals to extend the sound image out past the physical boundaries of the speaker
placements to surround channel information. These rear channel HRTF curves have much greater
peak to valley differences at center frequencies. These were chosen to cause rear channel
difference signals to virtualize farther behind the listener and directed to a different virtual position
as compared to front channel signals. Information that is equal (L+R) in the rear surround channels
