From Behringer:

• Switchable IKA (Interactive Knee Adaptation) program-adaptive compression circuitry combines the advantages of hard-knee and soft-knee characteristics

• Integrated De-esser with switchable male/female voice recognition removes excessive sibilance from your vocal tracks

• IGC (Interactive Gain Control) peak limiting circuitry combines clipper and program limiter for reliable and inaudible protection against signal peaks

• Switchable dynamic Enhancer for brilliant, lively audio even with heavy compression

• IRC (Interactive Ratio Control) expander/gate circuitry for virtually inaudible noise suppression

• Switchable Tube simulation for the extra warmth and transparency of classic tube circuitry

• Automatically or manually adjustable attack and release times

• Switchable Low contour filter prevents "pumping" due to low-frequency dominated compression

• Stereo couple function with independent output level settings

• Switchable side chain input with monitor function

• Separate 12-segment LED meters for input/output levels and gain reduction

• Dedicated "traffic light" Threshold and De-esser level displays

• Servo-balanced inputs and outputs with ¼" TRS and gold-plated XLR connectors

• Relay-controlled hard bypass switch with auto bypass function in case of power failure

• Internal switch-mode power supply (100 - 240 V~) for noise-free audio and low power consumption
