How to Change the Surround Mode Setup
The MX134 has Back Channel Surround Processing built-
in thus allowing for an additional enhancement of Dolby
Digital and DTS Movie Sound Tracks. There are three op-
tions for Back Channel processing; these include On, Off
and Automatic.
In the AUTO Mode, the MX134 will automatically
switch the Back Surround Sound Expander from Off to On
when the Digital Signal contains the added sound track in-
formation along with the “Back Surround Digital Flag”.
When in the ON Mode, any common or in phase Left/
Right Surround Signal Information contained in the Left
and Right Surround Channels will be expanded and sent to
the Back Surround Loudspeaker(s). The OFF Mode
switches the Back Surround Sound Decoder Off and no
sound will be heard from the Back Surround Loudspeakers.
Note: If the Back Surround Sound Expander is set to the ON
Mode and the sound track contains no common or in
phase Left/Right Surround Signal Information in the
Left and Right Surround Channels, the Back Channels
will reproduce the Left and Right Surround Channels
sound instead.
