Surround Mode; Dolby Digital - Teac PL-D2100 Owner's Manual

Listening Mode
Each time the LISTENING button is pressed, the mode is
changed as follows:
Normal mode:
Select this to enjoy surround sound. The sound is output from 5
speakers and the subwoofer.
Dolby Pro Logic II, Dolby Digital or DTS indicator lights on the
front panel display.
LT/RT:
This mode is useful when recording multi-channel sound on a
cassette tape deck or CD recorder connected via the AUDIO
OUT jacks. With a Dolby Pro Logic decoder (including TEAC
PL-D2100), the recorded sound can be decoded into multi-
channel sound.
STEREO:
Sound is output from front speakers and the subwoofer.
VSS:
This mode employs sophisticated digital processing to create
the illusion of "phantom" speakers. This mode allows you to
experience surround sound effects from Dolby Digital, Dolby
Surround or 2-channel (recorded in digital PCM or analog
stereo) sources, through just a single pair of front speakers.
< If you select STEREO or LT/RT during playback of DVD
recorded with DTS or DOLBY DIGITAL, the multi-channel
sound is downmixed to 2 channel.
< The LISTENING button doesn't work when the function is set
to "DVD" and no disc is set.
DTS
During playback of a DVD disc recorded in DTS format, the
surround mode is set to DTS automatically.
DTS Digital Surround delivers up to 5.1 channels with lower
audio compression than Dolby Digital. It provides the clarity
and dynamics of the original master soundtrack.

Dolby Digital

During playback of a DVD disc recorded in DOLBY DIGITAL
format, the surround mode is set to DOLBY DIGITAL
automatically.
Dolby Digital delivers up to 5 totally discrete, full frequency
audio channels (front left and right, center, and surround left
and right), plus 0.1 channel called LFE (Low-Frequency
Effects). LFE delivers a separate non-directional bass signal to
the sub-woofer for more dynamic deep bass sound effects.

Dolby Pro Logic II
Dolby Pro Logic II is an advanced matrix decoder that gives
you 5.1-channel surround sound (front left, center, front right,
surround left and surround right) from any stereo program
material, as well as Dolby Surround encoded material.
Compared with Pro Logic's monaural, limited-bandwidth
surround channel, Pro Logic II can provide two full-range
surround channels.
< DOLBY PRO LOGIC II will not work on monaural source.
Each time the U PL II MODE button is pressed, the mode is
changed as follows:
MUSIC:
The Music mode creates a rich and enveloping surround
ambience from stereo sources such as music CDs.
MOVIE:
This mode is optimized for movies or Dolby Surround encoded
materials. This mode is also appropriate for use with video
games.
MATRIX:
You might try this mode when you cannot get pleasing
surround effect in other modes.
PRO LOGIC:
Dolby Pro Logic is a matrix decoder that decodes the four
channels of surround sound (front left, center, front right and
surround) that have been encoded onto the stereo
soundtracks of Dolby Surround encoded material such as VHS
movies. The surround channel is monaural, but is played
through two surround speakers.
VIRTUAL:
Select this only when a virtualizer is connected.
< The U PL II MODE button doesn't work when the listening
mode is set to LT/RT, STEREO or VSS.
< The U PL II MODE button doesn't work during playback of a
DVD disc recorded in DTS or DOLBY DIGITAL 5.1 format.
