Lexicon MPX 550 manual LIVE-FOH Front of House, Typical Mastering Dynamics Control Adjustment

Program Descriptions

Lexicon

Typical Mastering Dynamics Control Adjustment (continued)

will cause the peak expansion meter to show three solid bars for short periods of time. Increase the ExpLvl parameter until the peaks in the source material sound slightly exaggerated. Then, reduce the setting until the peaks sound natural.

•Set the Ratio parameter to 4.00:1, the Attack parameter to 7.2msec, and the Release parameter to 1.4sec. Beginning at 0dB, reduce the setting of the Thresh parameter until the gain reduction meter moves between 0 and 3 to 6dB of gain reduction. If the output level sounds unnatural, increase the settings of the Attack and Release parameters. If output levels are too low after peaks occur, increase the setting of the Release parameter. If output levels are still too low after peaks occur, increase the setting of the ExpLvl parameter.

•Beginning at 0, adjust the Gain parameter setting until the output level meter shows peaks above –3dB.

LIVE-FOH (FRONT OF HOUSE)

Live-FOH programs are designed for live performances, with controls that are more convenient for live-sound engineers to operate. These programs use Dual Mono routings to accommodate the sound reinforcement systems (PAs) used in most small-to-mid-sized venues. Often, these systems provide limited channels and mono aux sends for effects.

For Live-FOH presets:

•Edit Page 1 contains the four most essential parameters for the first effect, and Edit Page 2 contains the four most essential parameters for the second effect. Non-essential parameters have been removed from the Edit Pages.
