z 6.1 channel matrix decoding

Some movies released after the summer of 1999 added a new
channel to its preexisting 5.1 channel. The new channel added
speakers behind the listening position. In the movie theaters,
these speakers are placed on the rear wall, on each side of the
projection room’s window.
The 6.1 channel system used in movie theaters is called Dolby
Surround EX system. However, to record on movie films, the 6.1
channel is converted to 5.1 channel using matrix encoding, and
the same number of channels are used as Dolby Digital and DTS
recordings. Recordings on the DVD also use the same signals.
A lot of movie theaters screen movies with matrix encoded
5.1 channel signals and this is not unnatural to the ears. However,
when a matrix decoder is used to create rear center speaker
signals, this simulates the same 6.1 channel sound as Dolby
Surround EX system in movie theaters.
This unit is equipped with a matrix decoder allowing for 6.1
channel sound production. With Virtual 3D technology, the rear
center signals can be enjoyed even without an actual rear center
speaker. When the front center speaker is not used, it is possible
to use this channel to output rear center signals.
Particularly with VIRTUAL MATRIX 6.1, speakers placed on rear
and side walls in the movie theaters are virtually created. As
reflections and reverberations are also simulated, you can enjoy
powerful sounds as if you are in a movie theater with Dolby
Surround EX system.
