  • Low and High frequency compression in Single Channel mode
  • 'Enhance' switch restores spectral balance of compressed signal
  • New Hard/Soft knee compression switch
  • New Adaptive Stereo Link circuit for accurate stereo imaging

The ARX AFTERBURNER II™ 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.

New LED metering provides accurate Level status, with separate Gain Reduction metering in easy to read 'wide scale' meters. There is also comprehensive LED indication of all operating functions and status in any mode.

Balanced Inputs and Outputs
On the rear panel, each channel has true differential Balanced inputs and outputs, on both XLR and TRS jack connectors. As well, each channel has a TRS jack Sidechain access insert point, for applications such as De-essing (when used with an external equalizer such as the ARX EQ 260). Other features include a true Hardwire 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.

With its smooth compression, intuitive user friendly layout, high density precision circuitry, and extensive user-variable operating parameters, the unique ARX Afterburner is equally at home in Studio, Installation, Broadcast and Sound Reinforcement environments. It can provide great sounding dynamics control effects that are not available with any other device.

QUADCOMP® II Four Channel Compressor/ Limiter

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 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.

Precision Circuitry
Internally, each compressor uses Class A VCA’s 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.

Sixgate™ Six Channel Opto-Coupler Noise Gate

Unique High Density design puts SIX Noise Gates in minimum rack space, with:
  • Fully updated circuitry and layout !
  • Fast, ultra low noise Opto-Coupler design
  • Intuitive, 'user friendly' layout
  • Balanced Inputs and Outputs
  • Sidechain/Key Input points on each channel
  • Hardwire Bypass switch and status LED on each gate
  • Flawless performance in any audio environment

The sheer amount of effects and signal processors required 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, in order to give engineers more control in less space, we've created the ARX Sixgate™; Six full function noise gates neatly housed in a compact, all steel 1 RU package, without sacrificing features or quality.

Why Six gates?
Research shows that the majority of noise gates get used on drum kits, which means using typically 5 to 6 gate channels. Compare this to the two or maybe 4 channels that most other units have, and you'll see the reason for the Sixgate’s success.

And, by using a minimalist approach to drum gates, the ARX Sixgate™ has enough gates left over for backing vocals and other instruments.

Industry Standard controls
On the brushed aluminum front panel the controls for each gate consist of the 'Industry Standard' controls for Release, Depth and Threshold, plus Red and Green LED displays to indicate Gate Open or Closed status, and an IN/OUT hardwire bypass switch with status LED.

In addition to this, each gate has a blank panel to write on for easy confirmation of gate assigns. No more pieces of masking tape stuck everywhere!

Ultra Low Noise
Internally, each gate has proprietary ARX ultra low noise high-speed opto-coupler circuitry with program dependent Attack time, which tracks the incoming signal to automatically determine optimum gate response.

Balanced Inputs and Outputs
The rear panel of the ARX Sixgate™ features true differential Balanced Inputs and Outputs for each gate, on insulated TRS jack connectors.

Each gate channel also has Individual Key Inputs/Sidechain access insert points which can be used either for gate control by an external signal, or for frequency sensitive gating (when used in conjunction with an external equalizer such as the ARX EQ260).

Universal AC Power
AC power range on the Sixgate™ is a universal 100 to 120V or 220 to 240V, and is connected to the unit via a standard 3 pin IEC connector, with built-in fuse and voltage switch.

The ARX Sixgate’s unique combination of High Density design, intuitive 'user friendly' controls, and clean uncluttered layout make it a truly useful audio tool for all applications.
