DC-1 Effects

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.)

SUBWOOFER LVL +0dB -5 to +5dB

EFFECT LEVEL +00dB -30 to +05dB

CUSTOM

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).
