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 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.
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.
