(see figure, above). However not all Dolby Digital programming is recorded in 5.1-channel
surround. For example, some Dolby Digital programming is recorded in two-channel
(matrix-encoded) Dolby Surround, in normal stereo, or monaural. In each of these cases,
an LFE subwoofer soundtrack may or may not be present. TheaterMaster will detect this
automatically, and will display this information by changing the pattern of circles on the
source indicator to most accurately depict the type of signal.
In any of these Dolby Digital modes, the
Stereo
button can be used to provide a two-
channel stereo downmix suitable for recording on a VCR or other two-channel recording
device. If the source material is surround-sound encoded (i.e., either 5.1-channel or Pro
Logic), then this two-channel downmix will be also be surround-sound (“matrixed Lt/Rt”)
encoded. The original Dolby Digital playback mode can be restored simply by pressing
the
Surround
button.
In the case of a Dolby Digital
stereo
signal, TheaterMaster also allows you to override the
automatic Stereo playback mode. This is achieved by pressing the
Matrix
or
Surround-
keys to give Matrix mode or Pro Logic decoding, respectively. (All such user-selected
overrides are flagged on the Main Screen with a “:”, e.g., “:Mat”, or “:ProL”.) These sur-
round-sound modes can greatly enhance the sound of some stereo soundtracks.* The user
is invited to experiment.
*Some early Dolby Digital Pro Logic soundtracks may not be properly flagged as Pro Logic. These soundtracks
will be displayed as “Dolby Digital Stereo” soundtracks on the Main Screen. For such soundtracks, Dolby Pro
Logic decoding is the preferable playback mode.
In the even rarer case of a Dolby Digital monaural soundtrack, TheaterMaster allows
the user to activate Mono-Enhanced playback mode by pressing the
Mono
button. This
provides the same benefits as for a PCM digital or analog monaural source.
3. DTS:
Enlightened Audio Designs is pleased to add DTS™ decoding capability to the Theater-
Master’s reference quality Dolby Digital and Pro Logic surround-sound capabilities. Dig-
ital Theater Systems™ (DTS) surround-sound technology provides ultra-high resolution
5.1-channel playback suitable for both movie
and
audiophile-quality multi-channel music
playback.
Using DTS decoding is simple. Simply place a DTS-encoded disc in your CD, DVD or
laserdisc transport connected to a digital input on the TheaterMaster, and play as any
other disc. The presence of a DTS soundtrack will be detected by the TheaterMaster,
and multi-channel DTS playback will commence automatically.
WARNING! In order to play a DTS-encoded DVD, your DVD player must have
the DTS logo on the front. Playback of these discs is fully automatic but may
require your DVD player’s setup to be configured for DTS bitstream output. On
the other hand, the earlier DTS-encoded CD format will play on most CD, DVD,
or laserdisc transports. The same goes for DTS-encoded laserdiscs, which will
play on most laserdisc players equipped with a digital output. Note that playing
back DTS-encoded CDs or LDs on these transports may result in a “burst” at the
start of playback. You should experiment with DTS at low listening levels to deter-
