Features:
Visually monitor input/output levels and gain reduction via 12-segment LED meters, de-esser level suppression via four-segment LEDs, and signal-to-threshold indication, and limiter activity.
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 mode removes excessive sibilance from 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 boosts treble only during compression for lively audio even during heavy gain reduction
IRC (Interactive Ratio Control) expander/gate circuitry for transparent noise suppression
Switchable tube simulation for the extra warmth of classic tube circuitry
Automatic or manual adjustment of attack and release times
Switchable sidechain high-pass filter prevents pumping due to extreme low-frequency compression
Stereo couple function with independent output level settings
Switchable sidechain 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 1/4" 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 for noise-free audio and low power consumption
Occupies just 1 RU of rack space
