Thanks for visiting ARX America!

Please look through it at your leisure and let us know if there is any other information you need. We are very aware that you have a wide range of competing pro audio products to choose from, and naturally we would like to do everything possible to help you choose ARX.

If we may, we'd like to point out a couple of things about ARX that you won't find in the technical specifications: By far the most popular comments from ARX first time users are "It's so easy to install and set up!" and "It sounds great!" and that's good, because we try and design things that way. To borrow a buzz phrase from the computer industry, the products are 'user-friendly'. We believe you shouldn't need a PhD to use any of our products, just a pair of ears and some commonsense.

Secondly, because here at the factory we're all pro audio users as well as designers, a lot of our products are unique. When we started ARX, we did so because we couldn't buy a lot of the products we wanted to use, products that we felt would make the job easier for the professional installer and the person at the console.

Our unique MaxiSPLIT and MaxiMIX have been installed in venues worldwide, including the 2000 Olympics in Sydney, Australia. Other popular installation products include the versatile MIXX and MIXXmaster 1 RU mixers.

We believe our new EQ 260 is the best Graphic Equalizer that you can buy, and many thousands of people around the world agreed with us and bought its predecessor.

The DI-6s is a product that stands alone as true pro-audio problem solvers. Our Sixgate™ is unique in giving you not four, but six full function noise gates in one compact unit, and our BarMIX zoner/mixer provides a complete music management system in 1 RU!

If this is the first time you've heard of ARX, thanks for your interest. We hope this has given you some background on the basic concepts behind ARX products. If you'd like to know more, just let us know.

2003 marked a milestone for ARX Systems, the well known Australian based designers and manufacturers of Professional Audio Equipment, as they celebrate their 20th anniversary.

ARX Systems was formed in Melbourne in 1983 by brothers Colin and David Park, and longtime friend Duncan Fry.

Several products introduced in the 80's have over the years become Industry Standards and are still manufactured today, albeit in an updated form to take advantage of improved manufacturing processes and most importantly higher quality Components.

These include the Sixgate 6 channel Noise Gate, Quadcomp 4 channel Compressor Limiter; and the venerable EQ 60 Dual 1/3rd Octave Equalizer, sales of which have now exceeded 10,000 units.

"At a time when it appears a lot of Pro Audio Manufacturers will end up being owned by Stylus manufacturers, Car Audio Companies or their Chinese OEM suppliers; Duncan, David and I are pleased that we've built an independent Company that still holds to its core values of designing and manufacturing a comprehensive range of products that people like to use, are reliable and are supported in a Professional manner.

"An old mate of ours, Hans Freytag, describes Pro Audio as 'the world's largest Cottage Industry', which is a fairly accurate description, even these days. It's certainly a most enjoyable industry to work in, as the last 20 years have proved."

Afterburner II
Not just another compressor limiter, but a unique signal processor. Easily set up as a two channel compressor, or a stereo linked compressor, or as a single channel, dual band compressor, able to compress low and high frequencies separately and mix them back to a single full range signal. At last, a compressor that brings an end to pumping and breathing effects. No longer will the low frequencies modulate the midrange and high frequencies, even under heavy compression. Plus, a unique Enhance switch for putting the punch and sparkle back into heavily compressed program material. Think of it as a 'smart' loudness control, or the 'sound good' switch! Great metering, Balanced Inputs and Outputs on XLR and jack connectors, plus Side chain insert. A truly unique and useful audio tool.

The simple, straightforward solution for supplying 2 audio zones with up to four stereo sources such as: Tape/cassette/DVD/CD decks, TV/Satellite/video audio, Juke Box/Karaoke systems, as well as a microphone. Totally intuitive, even for casual staff with no prior experience. Easily switch from the football/mud wrestling on Satellite to background music, to dinner orders, to karaoke. Interlocking switches with status LED’s for each source ensure that there is no risk of accidentally selecting two sources for the one zone. And because we're dedicated audio professionals, there is comprehensive 3 way EQ on the microphone and 2 way EQ on the stereo audio sources. An optional remote volume control completes this extremely useful package

As above, but switches video too! It's a multimedia world out there, and the AVstream is a super-intuitive solution that anyone can use!

It's got great specifications, but the first time you hold it in your hand you'll realize the thought that's gone into it. Just unscrew the captive locking screw on the rear and pull the lid back slightly. The top hinges up and the battery is right there waiting to be changed. No more messing around in the dark with a screwdriver trying to change batteries in a hurry. It's a DI with more than enough headroom to run cleanly at true professional levels; and has a SEPARATE speaker level input when you need to capture that amplifier sound. Plus, because we know what it's like out there, we've built in Phantom power support, so if you've got Phantom power available you won't have to worry about batteries.

DI-Plus 2
As above but in stereo!

The interface king! Six In/Six Out active DI boxes, a Six In/One out Line Mixer (at the same time), Individual Level controls, and a Master Level control (at the same time!), all in one value packed rack unit. Unbalanced Hi Z ins, Balanced XLR outs, with individual audio ground lift switches, the DI6s is a total pro audio interface solution.

But wait - there's More! Press a switch on the back and it becomes a One In/Six Out Microphone (or Line) splitter (audio distribution amp), with its own XLR Balanced Input, Gain control and individual level controls. AC powered, plus Phantom compatible. It's unique, and it really works. No engineer or system should be without one.

If you love your compact Digital (or Analog) mixing console, but wish it had more microphone inputs, ARX has the solution – the 8 Pre: eight channels of superb sounding Microphone Pre-amps in a compact 1 RU chassis. Balanced XLR in, balanced jack line out, 48V phantom power, Gain trim controls, phase reverse switches, pad switches, overload indicators - it's got the lot!

Line splitting is seemingly a simple task. But at pro levels you need headroom, and lots of it. Something the MaxiSPLIT has bags of! Ruler flat frequency response, fully balanced XLR inputs and outputs. The MaxiSPLIT has two modes - Dual channel One In/Four Out, or Single channel One In/Eight Out. The ARX MaxiSPLIT has applications in Sound Reinforcement, Installation and Broadcast industries.

Mixing it with the best! In Stereo mode the MaxiMIX effortlessly combines 4 hot stereo line level signals into a single stereo pair, in an intuitive user-friendly package. In Single Channel mode it will mix 8 line level signals down to one. Massive headroom, ruler flat frequency response, fully balanced XLR inputs and outputs. Ideal for multiple signal sources - for example DJ, Audio for Video, Karaoke, Live Sound - that need to run through the one speaker system.

Mixing Microphones has never been easier. The MIXX features 4 Channels of Balanced Mic or Line Inputs with Input Gain Trim, 3 way EQ, Volume Control and Pan. Phantom Power is also available by pressing a rear panel switch If you want to use the preamps of individual channels (say for recording) the MIXX also features Balanced Outputs on all Channels. Need more channels? The innovative ARX 'OpenBuss' connectors let the MIXX connect to the MIXXMaster as a channel expander.

With two Mic inputs identical to those on the MIXX, plus one Stereo Line input with 3 way EQ, and two Stereo Aux inputs, all 3 of them on RCA connectors, the MIXXMaster is an all round installation Mixing package. Channel 1 Mic input also features a switchable Override which 'Ducks' all other inputs when a signal is applied to the Channel 1 input. Master Output Levels complete the Package.

With the innovative ARX 'OpenBuss' connectors on the MIXXMaster, it can be connected with any number of MIXXMaster or MIXX units to provide an extremely flexible Multi Input, Multi Output (Zoning) Mixing System.

MSX 32
Splitting Microphone and Line Signals without degrading audio quality has never been easier, thanks to the new MSX 32 four channel active Mic/Line splitter. The thing to stress here is total quality and reliability. Eight Input Channels of low noise, high headroom Mic Pre-Amps are each split to 4 Electronically Balanced Outputs (Transformer Option available). For further flexibility, each channel can be linked to its neighbor for a possible total of One In, 32 Out! Phantom Power is switchable to each input. Taking over 2 seconds to reach 48VDC, ARX's unique Slow Ramping Phantom Power Supply ensures there are no Loudspeaker destroying transients or bangs. Each channel also has a 'Listen' (PFL) switch, plus +20dB Gain and -20dB Pad switches with status LEDs. An internal shielded toroidal power supply completes this superb package.

Today’s venues face a growing need to provide a multiplicity of audio feeds from presentations, conferences, orchestral performances and lectures. The advent of digital broadcasting, the growth of webcasts and direct-to-CD archiving highlight the deficiencies in audio splitting systems more than ever before. Whether the end product is a broadcast feed or CD sales of an unrepeatable lecture, performance or event, the end-users’ expectations of audio quality are higher than ever. And here's just the product to fulfill those expectations! The MSX 8 features Two Input Channels of low noise, high headroom Mic Pre-Amps each split to 4 Electronically Balanced Outputs. Linkable to One In, Eight Out, the unit also has –20 dB Pad switch and a +20dB Gain switch, plus silently switchable 48V Phantom power, all with status LEDs.

Quadcomp II®
The latest version of our classic industry leader. Four fully featured compressor limiters in one rack unit. Upgraded version of much loved pioneer product; the industry's first (in 1987) Four channel compressor in 1 RU! A world first, and now much copied. Smooth, quality compression at all ratios, using the latest state of the art VCA’s and RMS detectors. Balanced XLR Inputs and Outputs, naturally, plus a Sidechain insert point on each compressor channel. Each channel of the QuadcompII® is totally independent and can be used anywhere in the line level signal chain, or can be linked for accurate stereo tracking.

If you want total dynamics control over four channels, then the Quadcomp II® is what you need.

It's got the specifications and performance that professionals expect, plus a 'user friendly' layout that even entry level users can understand. Enough gates to handle a complete drum kit in one rack unit. No skimping on controls - each gate is fully featured with Threshold, Depth and Release controls, Balanced Inputs and Outputs, as well as a Key Input/Sidechain Insert. Everything is at your fingertips - no scrolling through time wasting menus - all controls are right there in front of you, all the time. Unique opto-coupler circuitry gives ultra low noise figures that traditional VCA gates would die for!
