AC-3 Effects and Parameters Lexicon

SURROUND EX (available as of software version 4) extracts and repro- duces the additional rear channel mixed into SURROUND EX encoded soundtracks. This parameter is automatically set to ON when both SIDE and REAR speakers are selected in the SPEAKER CONFIGURATION menu, and will not operate unless SIDE and REAR speakers are selected. SURROUND EX decoding can be engaged during playback of non-SUR- ROUND EX encoded 5.1 material, however, the information delivered to the rear channels may not be pleasing.

SURROUND MIX allows independent adjustment of the level of the sur- round channels. Many AC-3 encoded soundtracks sound better when down-mixed to two channels with the surround level increased by approxi- mately 2-3dB.

VOCAL ENHANCE boosts dialog in the center channel. By targeting specific frequencies, it can boost only dialog, without raising the entire center channel level (which would alter the output balance achieved during calibration).
