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. However,
when a matrix decoder is used to create surround
center speaker
signals, this simulates
the same 6.1 channel sound as Dolby
Surround
EX system in the movie theaters.
This unit is equipped
with the matrix decoder allowing
for 6.1
channel sound production.
With Virtual 3D technology,
the
surround
back signals can be enjoyed even without
an actual
surround
back speaker. When the center speaker is not used, it is
possible to use this channel to output surround
back signals.
Particularly
with 6.1 CH DECODING,
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
Surround
EX system.
