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 AFTERBURNER? is a unique Multi Mode compressor/limiter
designed for use in any professional audio dynamics control application.
Multiple Modes
The Afterburner can be set up and used in three different ways:
In Two channel mode, it performs as two independent compressor/limiters,
with 'industry standard' variable Threshold, Ratio and Output gain. In stereo
mode, our New Adaptive Stereo Link circuitry provides increased stereo
imaging accuracy when linking both channels as a stereo pair. A single front
panel switch puts the Afterburner into its alternative Mono mode, setting it up
as a Single channel, Dual Band compressor/limiter, with separate dynamics
control of both Low and High frequencies, opening up a whole new range of
gain control techniques.
Enhance Switch
In any mode, the Afterburner 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. Think of it as a 'smart' loudness control.

Tamper-Proof Crossover Points
The crossover points are determined internally by the value of 4 resistors per channel; changing
the resistor value changes the crossover point. This 'semi fixed' method avoids the pitfalls of
externally adjusted crossover points, making the crossover points tamper-proof once they are set.
Idle fingers can't fiddle with the crossover points and create havoc with the system!
As a handy guide, a list of common crossover points and their corresponding resistor values are
printed inside the unit's lid, and also set out in the Owner's Manual.
On the front panel are level controls for Low and High in dual channel 2 way mode, and Low, Mid
and High in single channel 3 way mode, with corresponding Outputs on the rear panel.

Balanced Inputs and Outputs
EC-2 has Balanced Inputs and Outputs, on XLR connectors.
The EC-2 also has an additional summed Mono Low output, for applications that need a Mono Low
feed (e.g. Left and Right full-range plus a single Sub Bass speaker).
High Pass Filter
There is also a preset 30 Hz HighPass filter to remove unwanted subsonics which can damage speakers
and waste amplifier power.
In addition, each output has up to +6 dB of gain available, to compensate for amplifiers and speakers of
differing sensitivities.
Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240VAC, and is connected to the unit via a standard
IEC connector, with built-in fuse and voltage change switch.
Uncompromising Audio Quality
Innovative circuit design is pointless unless it delivers stunning sound quality, and here the EC-2 excels.
It has been designed for uncompromising audio quality, and to achieve this, Linkwitz Riley 24dB (Fourth
Order) state variable filters are used throughout, ensuring a smooth Phase Correct transition through the
crossover region.
From Stage Monitors to Studio Monitors, from Front of House to the Front room of your House, the ARX
EC-2 is a crossover that is suited to any application that requires flawless, transparent sound.
You'll never compromise on Quality when you choose ARX
