Features
Unique High Density design puts SIX gates in
minimum rack space
Intuitive, 'user friendly' layout
Balanced Inputs and Outputs
Fast, low noise opto-coupler circuitry
Sidechain/Key Input points on each channel
Hardwire Bypass switch 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
Front panel 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.
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 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 conjuction 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 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.

Interactive Reference-Class 2-Channel Expander/Gate/Compressor/ Peak Limiter with
Integrated De-Esser, Dynamic Enhancer, Tube Simulation and Low Contour Filter 

Whether you?re recording, mixing or mastering, the COMPOSER PRO-XL MDX2600
gives you total dynamic control. It includes all of the features you would expect from
a reference class compressor?plus a voice-adaptive de-esser, a new dynamic
enhancer, authentic tube emulation and much more. These are some of the indispensable
tools for producing clean, consistent audio with virtually no loss in signal quality.

Features:
Switchable IKA (Interactive Knee Adaptation) program-adaptive compression circuitry
combines the advantages of hard-knee and soft-knee characteristics
Integrated de-esser with switchable male/female voice recognition removes excessive
sibilance from your vocal tracks
