MULTICOM PRO-XL
INTERACTIVE REFERENCE-CLASS 4-CHANNEL EXPANDER/GATE/COMPRESSOR/ PEAK LIMITER WITH
DYNAMIC ENHANCER AND LOW CONTOUR FILTER
Switchable IKA (Interactive Knee Adaptation) program-adaptive compression circuitry combines the=
advantages of hard-knee and soft-knee characteristics
IRC (Interactive Ratio Control) expander/gate circuitry for virtually inaudible noise suppression=
Switchable dynamic Enhancer for brilliant, lively audio even with heavy compression=
IGC (Interactive Gain Control) peak limiting circuitry combines clipper and program limiter for reliable=
and inaudible protection against signal peaks
Switchable Low contour filter prevents “pumping” due to low-frequency dominated compression=
Stereo couple function selectable for channels 1/2 and 3/4=
Ultra low-noise 4580 operational amplifiers and state-of-the-art VCA’s=
Separate 8-segment LED meters for input/output levels and gain reduction=
Selectable operating level (+4 dBu/-10 dBV)=
Servo-balanced inputs and outputs with ¼” TRS and gold-plated XLR connectors=
High-quality components and exceptionally rugged construction ensure long life=
Conceived and designed by BEHRINGER Germany=
