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 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 improves
on 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.
The back surround channel is not discrete, so 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.
Material encoded in the DTS-ES Discrete 6.1 format cannot carry DTS 96/24 information
because of bandwidth limitations as a result of the discretely encoded surround back channel
information.
When the SSP 7.1 detects DTS source material with the DTS 96/24 feature, the sampling
frequency of the signal is displayed by the SSP 7.1 Setup and Control Software. The SSP 7.1
Setup and Control Software also changes the text associated with the listening modes to reflect
that DTS 96/24 is being output.
