The goal of putting together an exceptional audio system is to enrich your life with outstanding sound. It’s all about playing the music. It isn’t about spending a lot of money, or solid gold knobs or jewel encrusted remote controls. And you don’t need all sorts of complicated features you’re never going to use. The key to building a great audio system is to use well-designed components with excellent technical performance and superb sound quality. Every Emotiva BasX component has been designed from the ground up to be part of an excellent audio system. They incorporate the latest cutting edge technology and all the features you need to give you the best possible listening experience.
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 Emotiva BasX products 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 a combination you just can’t find anywhere else – great sound and great value.
The BasX A-800 delivers real audiophile sound quality – and we’ve got the specs to back that up: 50 watts RMS per channel at less than 0.03% THD into 8 ohms (two channels driven); THD+N of less than 0.05%; and a signal to noise ratio of 110 dB referenced to full power.
While the BasX A-800 offers lots of performance, you won’t need a Ph.D. to install and use it. Just plug the BasX A-800 into any standard 115 VAC or 230 VAC line; it will figure out the correct voltage to use. A removable heavy-duty power cable is included, and, if you want to experiment with power cords, the BasX A-800 also accepts any industry standard IEC power cable. The speaker outputs are heavy duty five-way insulated binding posts that work equally well with bare wire, banana plugs, or spade lugs.
The BasX A-800 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-800 for a long time
True audiophile-quality sound - as with all of our amplifiers, the BasX A-800 was designed first and foremost to sound superb in all types of audio systems.
Great sounding Class A/B output stage - ensures smooth detailed sound and incredibly natural imaging - without a trace of harshness or strain.
Heavy duty linear power supply - with an oversized toroidal power transformer and plenty of current capacity to drive even difficult speakers.
Eight fully independent amplifier channels - each speaker output is powered by its own separate amplifier channel.
Bridgeable outputs - each pair of amplifier channels can be independently configured to act as two separate channels, or bridged into a single higher-powered channel.
Flexible input options - allow each pair of channels on the BasX A-800 to receive its input signal from its own independent input, or from the stereo bus input.
Automatic power switching - lets you configure the BasX A-800 for manual operation, or to be turned on by a trigger input, or when it senses an audio signal on any of its inputs.
Top quality parts and construction throughout - promise years of reliable service.
Totally stable - designed for use in the real world, with real speakers.
Heavy steel 2RU chassis with milled aluminum face plate - provide strength and rugged good looks.
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.
Audiophile-grade fault protection - entirely transparent under normal conditions, yet protects the amp and your other equipment from all common fault conditions.
Universal AC line voltage operation - the BasX A-800 is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz, and automatically detects the correct line voltage.
Standard IEC power inlet - fits all standard and audiophile IEC power cables.
Full three year warranty - ensures that you’ll be able to enjoy your BASX power amp for years to come.
