  • Overview

    The BasX A-500 is a five channel power amplifier that offers true audiophile sound quality at an affordable price. The BasX A-500 includes a carefully chosen set of important features, including a heavy-duty power supply, high-quality Class A/B amplification, transparent audiophile-quality fault protection, a trigger input and output, and industry standard unbalanced audio inputs. Modern manufacturing techniques, and careful design and parts selection, have enabled us to deliver all of this performance and great sound quality in the BasX A-500 at a far lower price than you might imagine.

    The BasX A-500 delivers 110 watts RMS per channel at less than 0.1% THD into 8 ohms (two channels driven); THD+N of less than 0.02%; and a signal to noise ratio of 120 dB referenced to full power. This makes the BasX A-500 the ideal amplifier to power a great sounding 5.1 channel surround sound system, a great way to upgrade the power amplifier section of your AVR, and a perfect companion to our MC-700 surround sound processor.

    BasX: The Foundation of a Superb Audio System

    The goal of putting together an exceptional audio system is to enrich your life with outstanding sound. It isn’t about spending a lot of money, or about fancy knobs and jewel encrusted remote controls; it’s all about playing the music. As a leading manufacturer of home audio equipment, we’ve noticed that a lot of people still don’t have high-quality audio in their lives. Some folks don’t have the budget to buy good equipment, while others don’t have the time to spend trying to figure out how to use it – and that’s exactly why we developed our new Emotiva BasX products. Our BasX components combine great sound quality, a carefully chosen set of genuinely useful features, and rock solid performance, with a simple yet elegant design.

    This unique combination allows us to offer a combination you just can’t find anywhere else – great sound and great value. All of the components in our new BasX line are priced to be within reach of every music lover. You don’t need to be rich to afford them, and you don’t need to be an engineer to figure out how to use them. They’re carefully crafted to give you many years of reliable and trouble-free service, and they’ll look great in your living room or on your audio rack. You can build a complete music system out of our BasX components that will give you a true audiophile listening experience. Or try adding one or two BasX components to round out your existing audio system. Great sounding audio doesn’t have to be expensive or complicated.

    BasX Simplicity

    While the BasX A-500 offers lots of performance, you won’t need an advanced degree to install and use it, and you won’t need to rewire your home. The BasX A-500 ships with a removable heavy-duty industry standard IEC power cable. Just plug it into an outlet, connect it to your preamp or processor and your speakers, and you’re done. Your BasX A-500 will figure out your line voltage automatically, and its speaker outputs are heavy-duty five way binding posts that accept bare wire, banana plugs, or spade lugs. We’ve used industry standard connectors, so you can upgrade the power cable or your speaker wires if you like; the BasX A-500 doesn’t really need all that fancy stuff, but it’s ready if you decide you want to add it later.

    BasX Quality

    The BasX A-500 is built to last, with a heavy duty steel chassis, solid milled aluminum faceplate, and high-quality parts and construction throughout. We expect you to enjoy your BasX A-500 for a long time – and we back that up with a full three-year warranty.

  • Sound Quality First

    • Low noise, wide bandwidth design lets you hear everything your high definition sources have to offer.

    • Totally stable with real world speakers in real systems; not just on a test bench.

    Solid Engineering And Quality Construction

    • A heavy duty linear power supply with an oversized toroidal power transformer delivers plenty of current to drive even difficult speakers.

    • Top quality parts and construction throughout for years of reliable trouble-free service.

    • Heavy steel 2RU chassis with milled aluminum faceplate offers strength and rugged good looks.

    • Double sided FR4 circuit boards with plated-through holes help optimize signal paths and minimize the need for point-to-point wiring.

    Flexible Signal Connections and Power Options

    • Unbalanced inputs via industry standard RCA connectors accept all standard unbalanced interconnects.

    • Heavy duty insulated five-way speaker binding posts allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs.

    • Remote trigger input and output allow the BasX A-500 to control and be controlled by other trigger-enabled equipment.

    • The BasX A-500 is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz and will automatically detect and configure itself for the proper line voltage.


    • Audiophile-grade fault protection is entirely transparent under normal listening conditions, yet protects the amp and your other equipment from virtually all common faults.

    • Full three-year warranty ensures that you’ll be able to enjoy your BasX power amplifier for years to come.

  • Circuit Topology

    • The BasX A-500 is a five channel power amplifier. The BasX A-500 combines classical audiophile amplifier architecture, based on a heavy-duty linear power supply, and a carefully designed high current short signal path Class A/B output stage, with advanced microprocessor-controlled monitoring and protection circuitry, to deliver superb sound quality at a truly reasonable price.

I've had dozens of amps from parasound,xtz,audiolab, I could go on and on but from now on I'm going to stick with my a-500 and ati amps.the a500 is just as good as all of those but is less $$

William T.

I have a 5.2 system in my garage consisting of Klipsch RP-280F's, RC-64iii, RP-150M's and dual SVS PC-2000's. I installed the A-500 as I wanted more power going to the five speakers. BIG DIFFERNCE!!! Sounds is clearer and deeper. Nice unit.
