How Do I Adjust the Surround Modes?

You can experience true home-theater sound with your Kenwood Audio-
Video Receiver. This receiver incorporates several listen modes to let you
enjoy surround sound with a wide variety of program sources. Each pro-
duces multiple channels of surround-sound, but each does it differently.
What is the THX?
•THX: Movie soundtracks are mixed in special movie theaters called
dubbing stages and are designed to be played back in movie theaters
with similar equipment and conditions. The soundtrack created for
movie theaters is then transferred directly onto Laserdisc, VHS tape,
DVD, etc., and is not changed for playback in a small home theater
environment.
THX engineers developed patented technologies to accurately trans-
late the sound from the movie theater environment into the home,
correcting the tonal and spatial errors that occur. On the KRF-X7775D,
when the THX mode is on, the THX technologies are automatically
added after the decoded signal.
Movies which have been encoded in Dolby Digital, DTS, MPEG, Dolby
Pro Logic, Stereo and Mono can all benefit from activating the THX
technologies. THX should be activated only when watching movies
which were mixed for playback in large movie theater environments.
THX need not be activated for music, movies that were made espe-
cially for television or shows such as sports programming, talk shows,
etc. This is because they were mixed in a small room environment.
•THX Surround EX: THX Surround EX - Dolby Digital Surround EX is
a joint development of Dolby Laboratories and the THX division of
Lucasfilm Ltd.
In a movie theater, film soundtracks that have been encoded with
Dolby Digital Surround EX technology are able to reproduce an extra
channel which has been added during the mixing of the program.
This channel, called Surround Back, places sounds behind the listener
in addition to the currently available front left, front center, front right,
surround right, surround left and subwoofer channels. This additional
channel provides the opportunity for more detailed imaging behind
the listener and brings more depth, spacious ambience and sound
localization than ever before.
