PRO LOGIC II MODE:
Selects the default mode that will be used when AUTO
Pro Logic is selected.
• PRO LOGIC - Emulates original Dolby Pro Logic
with 7kHz high frequency filter on rear speakers
and mono surround processing.
• VIRTUAL - Virtual surround for use without rear
loudspeakers.
• MUSIC - Recommended for Music. When com-
pared with the MOVIE mode, this mode provides a
more spacious front image and less high frequency
content from the rear channels for an effect similar
to a live concert space.
• MOVIE - (Default) The best choice for most content.
Works well with both music and movies. Full range
high frequency response from the rear speakers.
Autobalance circuitry keeps dialogue accurately
centered.
• MATRIX - Use for monaural source material.
• CUSTOM - User adjustable surround parameters.
PRO LOGIC II CONTROL:
Set the parameters for CUSTOM surround processing.
Specific adjustments may also be made to parameters
in Virtual, Music, Movie, and Matrix modes. The avail-
able adjustments will be shown in Blue. If a menu item
is grayed out, it cannot be adjusted in the selected
mode.
• Dimension - Allows you to gradually adjust the sound
field either towards the front or towards the rear.
• Panorama - Extends the front stereo image so that
it includes the surround speakers for an exciting
wraparound effect
• Center Width - Allows variable adjustment of the
center channel so that it is heard only from the cen-
ter speaker or in combination with the Left and
Right speakers.
• Surround Filter - Applies a mild high frequency
shelf filter to the rear surrounds. This results in a
more natural soundfield on music since ambient
sounds normally have a high-frequency rolloff
induced by room reflections and absorption.
• Surround Coherence - Keeps left and right sur-
round speakers coherent for a more focused rear.
Keep “off” for a more spacious, diffused surround
effect.
