Dolby Pro Logic II Music & Custom Settings
The Cinema Rhapsody Mach 4 features Dolby Pro
Logic decoding. While the parameters behind the
Dolby Pro Logic II Movie mode are not adjustable
(the top image of the PC program shows that all
features are greyed-out when in this mode), some
of these parameters are adjustable for Dolby Pro
Logic II Music mode (middle screen shot). All of
the parameters are available for the three Dolby
Pro Logic II Custom modes. In order to make
changes (which occur in real-time), you must rst
select a Pro Logic II Music or Custom Mode.
Center Width - Using a scale from 0 (off) to 7, Center
Width spreads the center channel image toward
the right and left. Remember that this is still a
mode that is based on Dolby Prologic decod-
ing and as such, mono (i.e. vocals in music) are
extracted from the right & left tracks and passed
onto the center channel.
Panorama On or Off - When Panorama is ON, the
sound eld from the front speakers is pulled into
the surround speakers.
Dimension Control - Using a scale from 0 (off) to
7, Dimension Control is the level of audio that is
pulled to the surround channels when Panorama
is ON.
Additional features available when rst selecting
one of the three Prologic II Custom modes include
Surround Shelng lter, Surround Delay On/Off,
Polarity Control, Matrix Coefcient Control and
Auto Balance On/Off.
Once features are set for either Prologic II Music
or any of the three Custom modes, it remains set
for that mode.

knob. Then navigate to PRO LOGIC II and press
