Emotiva BasX A-150, a high-quality two channel power amplifier at an incredible price
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.
Why is BasX so special?
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.
The BasX offers all the essential features that make a great audio component. The circuitry in the BasX A-150 features a heavy duty linear power supply, great sounding high-current short signal path Class A/B amplifier modules, a trigger input and output, and industry standard unbalanced audio inputs. It also includes audiophile-quality fault protection that’s completely transparent in normal operation, yet protects the A-150 and your other equipment from common fault conditions.
The BasX A-150 delivers real audiophile sound quality – and we’ve got the specs to back that up: 75 watts RMS per channel at less than 0.1% THD into 8 ohms; THD+N of less than 0.02%; and a signal to noise ratio of 120 dB referenced to full power.
While the BasX A-150 offers lots of performance, you won’t need a Ph.D. to install and use it. Just plug the BasX A-150 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-150 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.
