Dolby Pro Logic II Dolby Pro Logic II is the latest version of Dolby Laboratory’s Movie and Pro Logic:
benchmark surround technology that creates or decodes full- 10 ms – 25 ms,
range, discrete left, center, right, right surround and left surround Initial Setting – 10 ms,
channels from matrix surround-encoded programs and conventional Music:
stereo sources. The Dolby Pro Logic II Movie mode is optimized for 0 ms – 15 ms,
movie soundtracks that are recorded with matrix surround, by Initial Setting – 0 ms
creating true rear left, center and right signals. The Dolby Pro Logic II
Music mode should be used with musical selections that are recorded
with matrix surround or with normal stereo mode, creating discrete
rear left and right signals. The Dolby Pro Logic mode provides
decoding that is identical to the original Dolby Pro Logic processing
for those who prefer that presentation. In this mode, the surround
channels are fed an identical monaural signal.
Dolby 3 Stereo Uses the information contained in a surround-encoded or two-channel No surround channels
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.
Theater The Theater mode creates a sound field that resembles the Delay time not adjustable
acoustic feeling of a standard live performance theater, with
stereo and even pure mono sources.
Hall 1 The two Hall modes create sound fields that resemble a small Delay time not adjustable
Hall 2 (Hall 1) or medium-sized (Hall 2) concert hall, with stereo
and even pure mono sources.
5-Channel Stereo This mode takes advantage of multiple speakers to place a stereo signal No delay is available for
at both the front and back of a room. Ideal for playing music in situations this mode
such as a party, it places the same signal at the front-left and surround-
left, and at the front-right and surround-right speakers. The center channel
is fed a summed mono mix of the in-phase material of the left and
right channels.
Surround Off This mode turns off all surround processing and presents the pure No surround channels
(Stereo) left and right channel presentation of two-channel stereo programs.
