Features
Dynamic new update of Behringer's popular "world standard" interactive stereo compressor-limiter-expander-gate.
Expander/gate section now features swept ratio parameter.
Switchable input/ouput meter for more effective signal monitoring.
New high-end VCA ensures truly exceptional audio performance.
Sub-miniature Surface Mount Design allows extremely high component density ensures greater reliability.
Extremely short signal paths provide a noticeably superior sound.
Provides increased dynamic energy to channels, subgroups and mixes and increased projection for vocals while preventing system overload.
Fully automatic or manual compression modes.
User selectable "soft-knee"/"hard-knee" switch to put total control in the users hands.
Interactive Gain Control peak limiter combines clipping and program limiting.
Contor switch prevents over-compression from LF content.
Switchable true stereo or dual mono operation.
Special IRC circuit for exceptionally quiet Expansion and Gating.
Switchable +4 dBu and -10 dBV operating levels.
Switchable external key inputs with Key Listen feature.
Servo balanced inputs and outputs on XLR and 1/4 in. connectors.
