"_";q 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 the movie theaters is called Dolby
Surround EX system. However. to record on movie films_ this 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 movie with matrix encoded
5.1 channel signals and this is not unnatural to the ears. Howeven
when a matrix decoder is used to create rear center speaker
signals_ this simulates the same 6.1 channel sotn'_d as Dolby
Surrotmd EX system in the movie theaters.
This trait is equipped with the matrix decoder allowing fur 6.1
channel sound production. With Virtual 3D technology, the rear
center signals can be enjoyed even without an actual rear center
speaken When the fi'ont 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 in the movie theater that uses Dolby
Surrotmd EX system.
