ARX are based in Highett Australia and are designers and manufacturers of a complete range of Pro Audio solutions – equalizers, line mixers and splitters, mic pre-amps, direct boxes, compressors, noise gates, concert and self powered speakers, amplifiers, active mic splitters, and much more.

The ARX web site also contains a wealth of information to help you find products you need.

ARX first time users often comment “It’s so easy to install and set up!” and “It sounds great!” and that’s good, because ARX 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.

When ARX founders started the company they dis so because they couldn’t buy a lot of the products they wanted to use. So they set about designing and building products that they felt would make the job easier for the professional installer and the person at the console.
