Features Four Independent Compressor Channels Channels 1 and 2, 3 and 4 are stereo linkable 7 LED Gain Reduction metering Balanced XLR Inputs and Outputs Sidechain Insert points Intuitive, user friendly layout Flawless performance
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. 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 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 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. Precision Circuitry 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.

Innovation The ARX COMPO? is a unique compressor/limiter designed for use in any professional audio dynamics control application, packaged in a compact 1 RU chassis.The COMPO operates as two independent compressor/limiters, with 'industry standard' variable Threshold, Ratio and Output gain controls. A Stereo Link switch on the front panel lets both channels track as a stereo pair in a Master/Slave configuration. Enhance Switch The COMPO features an 'Enhance' switch, which provides frequency restoration to preserve the spectral balance of the audio signal, compensating for the sagging Low and High frequency response of compressed program material. The best way to think of it is as a 'smart' loudness control. Wide Scale metering There is comprehensive LED indication of all operating functions and status. Above or Below Threshold LEDs on each channel give you instant visual confirmation of compressor activity, as well as easy to read LED Gain Reduction meters. Balanced Inputs and Outputs On the rear panel, each channel has true differential Balanced inputs and outputs, on both XLR and TRS jack connectors. Other features include an Active/Bypass switch for each channel, and passive RFI filters on the inputs. Universal AC Power AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a removable power lead and standard 3 pin IEC connector, with built-in fuse and voltage change switch. ARX Quality With its smooth compression, intuitive user friendly layout, high density precision circuitry, and extensive user-variable operating parameters, the ARX COMPO is the ideal installation 'set and forget' compressor, and is also equally at home in Studio, Broadcast and Sound Reinforcement environments.
Every day, ARX Audio interface products solve audio problems for thousands of people around the world.
