How Do I Adjust the Surround?
What are Listen Modes?
•Dolby Digital: Dolby Digital uses an encode/decode process based
on its theatrical digital surround sound technology. The five main
channels are full-frequency and independent, so sound can completely
envelop you or soar anywhere in the room, just like at the movies.
Compared with Dolby Pro Logic, Dolby Digital has more clarity,
greater surround envelopment, and more realistic sound movement
between channels.
Although a full set of speakers (front left and right, center, surround
left and right, and a subwoofer) is required for true Dolby Digital
surround sound, this receiver lets you enjoy Dolby Digital program
sources, even if you connect fewer speakers.
•DTS : DTS has five full-frequency channels that create effects nearly
identical to those in a theater. Sounds seem to zoom from one place
to another or entirely surround you. Like Dolby Digital, DTS has much-
improved clarity, surround and sound movement capability compared
with Dolby Pro Logic. This listen mode is available on CD, LD, and
DVD media. DTS is a strictly digital format that can be supplied only
by a CD, LD, or DVD player that supports DTS sound. If you attempt
to listen to DTS encoded media through the analog connections to
your new receiver, you will experience digital noise (loud static).
•DT S-ES Discrete 6.1, D TS-EX Matrix 6.1: Both DTS-ES Discrete 6.1
and DTS-ES Matrix 6.1 add the surround back channel audio to the
DTS 5.1-channel format to improve the acoustic positioning and
makes acoustic image movement more natural with the 6.1-channel
reproduction. This receiver incorporates a DTS-ES decoder, which can
handle DTS-ES Discrete-encoded and DTS-ES Matrix-encoded program
sources from DVD, etc.
DTS-ES Discrete 6.1 features digital discrete recording of all channels
including the surround back channels and higher quality of audio
reproduction.
The surround back (SB) signals are encoded in the surround channels
(SL, SR) and decoded to the SL, SR and SB channels during playback.
The THX processor then corrects these signals to match the home the-
ater reproduction and outputs them in the 6.1-channel signals.
