How Do I Adjust the Surround Modes?
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.

Dolby Pro Logic/Dolby Pro Logic II:
Dolby Pro Logic reproduces a
surround sound like in a movie theater from Dolby Surround-encoded
program source (videotape or LaserDisc software carrying the Dolby
Surround logo), and features excellent sound movement on the front
and a surrounding atmosphere of movie theaters. Meanwhile, Dolby
Pro Logic II decodes a signal encoded in 2 channels into 5-channel

Only receiver and controller products bearing the THX Surround EX
logo, when in the THX Surround EX mode, faithfully reproduce this
new technology in the home.
This product may also engage the "THX Surround EX" mode during
the playback of 5.1 channel material that is not Dolby Digital Sur-
round EX encoded. In such case the information delivered to the Sur-
round Back channel will be program dependent and may or may not
be very pleasing depending on the particular soundtrack and the tastes
of the individual listener.
