DC-1 Effects
Lexicon
Pro Logic This Effect provides Dolby Pro Logic Surround decoding designed for any Dolby Surround encoded movies, music, or television programs. The Pro Logic effect is an industry standard. Lexicon's proprietary auto azimuth correction makes it an improvement over other versions. (Even more dramatic improvement has been implemented in more recent effects, such as Logic 7 or TV Matrix.)

AUTO AZIMUTH is short for auto azimuth error correction/automatic input balance. Auto Azimuth should be set to ON for films, and OFF for music. When ON, special patented algorithms continually monitor the input signal and adjust both the relative level and time offset of the two channels to keep the dialog properly centered and special effects properly localized. This automatic feature is the reason the unit does not need an input balance control for Dolby Surround decoding.
DIALOG ENHANCE boosts dialog in the center channel. By targeting specific frequencies, it boosts dialog without raising the entire center channel level (which would alter the output balance achieved during calibration).
SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.
EFFECT LEVEL adjusts the loudness of all speakers except the center channel. This can be extremely useful in compensating for soundtracks in which the dialog level is too low (decrease EFFECT LEVEL) or when you want to make the surround presentation more spectacular (increase EF-
FECT LEVEL).
