ARX - Quadcomp II
The sheer amount of effects and signal processors necessary for today's standards of audio production puts a great strain on the available space in equipment racks, both in the studio and on the road.
So, ARX would like to introduce the ARX Quadcomp®II. An all-new upgrade of the classic award-winning ARX Quadcomp®, the very first four channel 1 RU compressor.
You’ll notice that we haven’t strayed very far from our original design concept. The Quadcomp II is still four variable ratio Compressor/ Limiters neatly housed in a compact all steel 1 RU package. However, all new low noise/low distortion circuitry, better metering plus XLR inputs and outputs put the Quadcomp II in a class of its own.
More Control, Less Space
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.
Balanced Inputs and Outputs
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 (such as the ARX EQ260).
Compressor pairs 1 and 2, 3 and 4 also have rear panel mounted Stereo Link switches for accurate stereo tracking. When switched IN, the first channel becomes the master and controls all the functions of the second except Output gain.
Universal AC Power
AC power range is switchable 100 to 120V, or 220 to 240V, and is connected to the unit via a standard IEC connector, with built-in fuse and voltage switch.
Whatever the application – Channel insert, Bus insert, Master Outputs, Monitor outputs, Crossover outputs, the Quadcomp II’s unique High Density design, precision Low Noise circuitry and clean uncluttered layout make it a truly useful audio tool for all applications.
