Product description
Reference-Class 4-Channel Expander/Gate/Compressor/Peak Limiter with Dynamic Enhancer and Low Contour Filter
Key Features
- ✓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
- ✓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
- ✓Internal switch-mode power supply (100 - 240 V~) for noise-free audio and low power consumption
