Extron Electronics SSP 7.1 User Guide - Manual (Page 73)

DTS
This mode is used with DTS Digital Surround encoded source formats. It also produces up
to 5.1 discrete channels (center, left and right front, left and right surround, and a low
frequency effects channel).
This is the default mode for DTS-ES Matrix 6.1 source formats when the system is set
up for 3.0 to 5.1. It can be used with this source format to play the audio without the
matrix-encoded back channel information.
DTS 96/24
This mode is used with DTS Digital Surround source formats that have been encoded using
DTS 96/24. It also produces up to 5.1 output channels with audio sampled at 96 kHz at
24 bit depth.
This is also the default listening mode for DTS 96/24 ES Matrix 6.1 source formats for
systems with a 3.0 to 5.1 speaker configuration or if the listener wants to play the audio
without the matrix-encoded back channel information.
DTS-ES Matrix
This mode decodes DTS-ES Matrix 6.1 source formats, for use in a 6.0 to 7.1 system. Upon
playback, the additional surround back channel signal is decoded from the surround left and
right channels.
The listening mode can also be used with DTS Digital Surround sources where a surround
back channel is created through matrix processing.
DTS 96/24 ES Matrix
This mode is similar to DTS 96/24 but is used with DTS-ES Matrix 6.1 source formats. It can
also be used to extend DTS 96/24 source formats from 5.1 to 6.1 by creating a surround
back channel using matrix processing.
DTS-ES Discrete
This mode decodes DTS-ES Discrete 6.1 source formats and reproduces all 6.1 channels,
including the center channel information that was recorded independently, using the Digital
Discrete system.
Dolby Digital EX
This listening mode decodes source material that was recorded using Dolby Digital
Surround EX technology. It uses matrix mixing to produce extended surround back channel
effects, which create 6.1 outputs from 5.1 source formats. When used with 6.1 source
formats, the original back channel information is replaced by a matrix mixed sixth channel.
NOTE: This mode is available only when the SSP 7.1 is set up for 6.1 or 7.1 outputs and
a multichannel Dolby Digital source format is available.
Dolby Pro Logic
This mode decodes source audio that is encoded in two-channel Dolby Surround to
provide four-channel playback (center, left, right and mono surrounds). Sources include
videocasettes, DVDs, and TV broadcasts.
Logic steering techniques extend the impact of the sound track over a wider listening area.
This listening mode creates a mono surround channel with a high frequency roll off above
7 kHz.
