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.
An advanced mode that extracts the maximum surround information from either
surround-encoded programs or conventional stereo material.When used with encoded
material, decoding is more accurate in terms of the placement of sounds, and fades and
pans are much smoother and more realistic than with other decoding techniques. Logic 7
also delivers increased spaciousness and a wider sound stage when it is used with con-
ventional stereo recordings and music programs.The Logic 7C or Cinema mode is tailored
to provide an optimal sound field for movie soundtracks.The Logic 7M or Music mode
uses a decoding formula that is best suited to music.
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.
Surround processing uses matrix surround decoding to simulate a standard movie or
stage theater.
When only the two front-channel loudspeakers are used, Harman’s patented VMAx mode
delivers a three-dimensional sound space with the illusion of “phantom speakers” at the
center and surround positions.
This mode turns off all surround processing and presents the pure left and right
channel presentation of two-channel stereo programs.
