Description
Incoming Bitstream or Signal
DTS-ES Matrix
DTS Extended Surround adds a single surround back channel to DTS 5.1
• DTS-ES Matrix
digital surround sound. The Matrix version includes the surround back
channel information “matrixed” into the left and right (side) surround
channels, for compatibility with 5.1-channel systems.
DTS-ES Discrete
DTS-ES Discrete is another Extended Surround mode that adds a surround • DTS-ES Discrete
back channel, but this information is encoded discretely on the disc, and
is not derived from information contained in the surround channels.
DTS Stereo
Delivers a 2-channel downmix of DTS Digital materials, or presents

Logic 7
A Harman International proprietary technology, Logic 7 technology enhances

Mode Group
2-channel and matrix-encoded recordings by deriving separate information
for the surround back channels. This provides more accurate placement of
sound, improves panning and expands the sound field, even when used
with 5.1-channel systems. Logic 7 technology uses 96kHz processing, and
is available in 5.1-or 7.1-channel modes. Three variants are available.

Especially suited to 2-channel sources containing Dolby Surround or matrix • Analog (2-channel)

5-Channel Stereo
Useful for parties, the left- and right-channel information is played
