PRO LOGIC II MODE:

PRO LOGIC II MODE:

PRO LOGIC II CONTROL:

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.

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.
