ARX Quadcomp II

Four-Channel Compressor/ Limiter

The Quadcomp II provides four variable ratio Compressor/ Limiters neatly housed in a compact all steel 1 RU package.The new low noise/low distortion circuitry, better metering plus XLR inputs and outputs, put the Quadcomp II in a class of its own.

On the front panel, each channel has the 'industry standard' individual controls for Threshold, Compression Ratio and Output, plus a new 7 LED Gain Reduction display for accurate visual indication of the amount of gain reduction being applied to the program, and an IN/OUT hardwire bypass switch.
In addition to this, each channel has a blank numbered panel to write on for easy confirmation of compressor assigns.

Internally, each compressor uses Class A VCAs and true 2 pole averaging RMS/DC converters for low distortion and accuracy, plus program dependent attack and release time, which automatically determines optimum compressor response.

The rear panel has true differential Balanced XLR Inputs and Outputs for each compressor. Each compressor has a TRS jack Sidechain access insert point, for frequency sensitive compression, De-essing, etc. in conjunction with an external equalizer.
