ARX - Sixgate

by ARX
Currently Out Of Stock

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 aluminium 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 TipRingSleeve 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 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.
