Dolby Digital Surround EX

(3/2.1)
Dolby Digital Surround EX is a commercial format that reproduces the center
channel information through speakers placed directly behind the listener.
The back surround information is matrix-encoded onto the right and left surround
channels of conventional Dolby 5.1 formats. If there is no back channel speaker, the
information for that channel is played through the right and left surround speakers.

DTS Source Formats (DTS)

Inputs 1- 4 only.

DTS 2-Channel

(2/0)
DTS 2-Channel is a specific DTS encoded stereo format. Material encoded in
this source format is typically found in DTS-HD Blue Ray DVDs and is primarily
intended for playback by the left and right front speakers. When this source format
is present, both the DTS and the 2-CH LEDs will light.

DTS Digital Surround

(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0)
DTS Digital Surround is a 5.1-channel surround sound format similar to Dolby
Digital 5.1. As with the Dolby format, there are five full frequency channels (front
center, front left, front right, surround left, and surround right) and an additional
LFE channel.
DTS 96/24
(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1 or 1/0)
DTS 96/24, provides high quality audio reproduction of music and movies from
DVDs encoded with DTS Digital Surround source format information. The 96
kHz sampling frequency is an improvement over the more typical 48 kHz. All
DTS formats have 24 bit depth, which allows more audio information to be stored
compared with the normal 16 bit depth.

DTS-ES Matrix 6.1

(3/2.1)
DTS-ES Matrix 6.1 is a 5.1 channel format with the back surround channel matrix-
encoded into the right and left surround channels. This is achieved in much the
same way as the front center channel is matrix-encoded into the front left and right
channels of the Dolby Pro Logic format. Since the back surround channel is not
discrete, this is not a true 6.1 source format.

DTS 96/24 ES Matrix 6.1

(3/2.1)
This mode is similar to DTS-ES Matrix 6.1 but also has DTS 96/24 encoded.

DTS-ES Discrete 6.1

(3/3.1)
DTS-ES Discrete 6.1 has a back surround channel that is discretely encoded into the
DTS bitstream. This format gives better sound spatialization for complete sound
localization and sound pans (the movement of a sound source through the sound
field). This format provides a data flag to signal the decoder that the bitstream
contains an extra channel.
