Available only with digital input sources encoded with DTS data. Available on special
DVD, LD and audio-only discs, DTS provides up to five separate main audio channels and
a special dedicated low-frequency channel.
The standard mode for analog surround sound decoding. It uses information encoded
in a two-channel stereo recording to produce four distinct outputs: Left, Center, Right and
a Mono Surround channel. Use this mode for accurate reproduction of programs bearing
the Dolby Surround, DTS Stereo, UltraStereo or other “Surround” logos. Surround-encoded
programs include videocassette, DVD and LD movies, TV and cable programs, radio
programs and audio CDs. Dolby Pro Logic processing may also be used to provide a
pleasing surround effect with some stereophonic source material that does not carry
surround encoding.
Uses the information contained in a surround-encoded or two-channel stereo program to
create center-channel information. In addition, the information that is normally sent to the
rear-channel surround speakers is carefully mixed in with the front-left and front-right
channels for increased realism. Use this mode when you have a center-channel speaker
but no surround speakers.
These modes are designed for use with stereo recordings. They provide a sound-field
effect that simulates the complex combination of direct and reflected sounds that
create the rich reverberant atmosphere of a medium-sized concert hall (Hall 1) or a
large concert hall (Hall 2).
Surround processing uses matrix surround decoding to simulate a standard movie or
stage theater.
This mode turns off all surround processing and presents the pure left and right
channel presentation of two-channel stereo programs.
