APPENDIX
Surround Mode Description
DTS-HD DTS-HD is a new high-definition audio format that complements the
high-definition video found on Blu-ray Discs and HD-DVD discs. It is transmitted
using a DTS core with high-resolution extensions. Even when only DTS 5.1
surround sound is desired (or available, if the multizone system is in use),
the higher capacity of high-resolution discs serves up DTS at twice the bit
rate used on DVD-Video discs.
DTS-HD Master Audio DTS-HD Master Audio technology delivers bit-for-bit reproductions of the
studio master recording in up to 7.1 channels, for an incredibly accurate
performance.
DTS-ES Matrix DTS Extended Surround adds a single surround back channel to DTS 5. 1
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
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
a matrix-encoded surround presentation.
DTS Neo:6 DTS Neo:6 analog processing is available with DTS and DTS 96/24
Mode Group signals and 2-channel analog or PCM signals to create a 3-, 5- or 6-channel
presentation.
DTS Neo:6 Depending on the number of speakers in your system, select 3-, 5- or
Cinema 6-channel modes, enhanced for movie or video presentations.
DTS Neo:6 Available only in 5- and 6-channel modes, creates a surround presentation
Music suitable for music recordings.
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.
Logic 7 Especially suited to 2-channel sources containing Dolby Surround or matrix
Movie encoding, Logic 7 Movie mode increases center channel intelligibility.
Logic 7 The AVR 254 is programmed at the factory to default to this mode for
Music 2-channel signals. Logic 7 Music mode is well suited to conventional
2-channel music recordings.
