About ARX Power Amplifiers: an overview of the basic concepts

Our History

ARX was one of the first companies in the world to bring out a high powered amplifier in only 2 rack spaces - the legendary SS700! A concept that has been embraced by virtually every amp manufacturer since then. Today, thousands of amplifiers later, we’ve had greater experience in getting more from less than just about anyone else!

Our Design Philosophy

Our philosophy is a simple one: #1. Make amplifiers that first and foremost deliver superb, transparent sound quality. #2. Make them as compact as possible without compromising reliability and ease of service. #3. Make them light but strong. Some amplifiers are just designed heavy, because it's easy. It takes far more time and effort and money to design them light! Well, here at ARX, we’ve never taken the easy option. We've put in the time and effort with advanced computer modelling techniques which have enabled us to put the strength where it’s needed, and to reduce excess weight where possible.

Real World Power     Go to Mosfets discussion

#4. Make them powerful. Less weight shouldn't mean less power. Every ARX amplifier's power is rated at the industry standard RMS rating. That’s true continuous RMS power, not music power, peak music power, instantaneous power, or any other unquantifiable esoteric standard that can make an amplifier appear to deliver something it doesn’t. Let's face it, this is Professional audio, not car audio! This true power output comes from state-of-the-art components - latest generation Mosfet output devices, and a low mass, high efficiency toroidal transformer based power supply. No marginally designed multi rail voltage wobblers here - when it comes to horsepower, there’s no substitute for cubic inches! From 100 watts to 1,000 watts RMS, ARX amplifiers provide power to to drive any system, and power to deliver the low frequency impact that lesser amplifiers can only dream about.

Protection systems

#5. Make them smarter by building in more protection. Every ARX amplifier has protection systems onboard to help it cope with less-than-perfect conditions. A unique ‘Headroom Enhance’ circuit provides maximum output levels without clipping, so both the amplifier and the speakers live longer Relay switched DC sensing, that instantly disconnect the speaker outputs if something unpleasant is detected Input/Output muting at turn on/off, to avoid damaging thumps when the amplifier is switched on or off. All sensitive components are carefully chosen for their high fault tolerance: our diode bridges, transformers, capacitors are all over-designed to handle excessive conditions
