Emotiva XPA HC-1 monobloc power amplifier

Emotiva XPA HC-1

The new XPA HC-1 is a true monoblock power amplifier and features a single high-power XPAGen3 amplifier module, powered by its own dedicated massive switch mode power supply (SMPS). If you’ve been considering our other XPA Gen3 models, but you’ve really got your heart set on monoblocks, then the XPA HC-1 is the amplifier you need to get your hands on.

The chassis on the XPA HC-1 is the same height and depth as our other XPA Gen3 models, but half as wide, making it easy to position an XPA HC-1 near each of your main speakers or arrange several of them side by side in your equipment rack. We’ve kept the sides clear of ventilation slots, so there’s no problem setting them directly next to each other. If you’re looking for a single amplifier to power your center channel, a pair of monoblocks to power your main speakers, or a full set to power a surround sound system, then the XPA HC-1 is probably the perfect amplifier for you.

Consider using a single XPA HC-1 to power your high-end center channel, or a pair to power your front left and right speakers, or a set of three to power all three critical front channels. And, of course, a full set of XPA HC-1 amps, powering all of your speakers, would be tough to beat.

Configuration:
1 High-Powered Single-Channel Modules

Power output:
300 watts RMS into 8 Ohms
600 watts RMS into 4 Ohms

Why You Need A Dedicated Power Amplifier

Most experts agree that, if you want the absolute best sound quality and technical performance, separate components are the way to go. Our new Third Generation XPA series power amplifiers are all designed from the ground up to perform a single critical task – to accurately reproduce every detail and nuance of your music. By focusing all of our efforts on that one goal, we’ve been able to design an amplifier that performs its job with remarkable precision and avoids most of the compromises that limit lesser designs.

The Joys of Joining the Monoblock Club

All of the models in our XPA Gen3 line of amplifiers perform really well and sound superb. However, to a true audiophile, “there’s just something about a monoblock,” and that probably won’t ever change. Because each channel has its own amplifier, its own dedicated power supply, and its own chassis and power cable, you’ll never have to even wonder about interactions between the channels, or about running a tiny bit short of power when a particularly demanding piece of music comes along. Owning monoblocks is like owning a sports car: you may not need them, but you know you want them, and here’s your chance. Wanting to rack mount your new amps?

Experience Meets Cutting Edge Technology

When we set out to design the latest version of our XPA series of amplifiers, we analyzed everything in every amp we’ve ever made, from front to back, inside and out. By combining years of design experience, with a thorough understanding of recent advances in audio technology, we were able to determine several areas where we could improve on our previous designs. After carefully weighing all the options, we kept the best features of our previous models, added some new technology where we determined it would actually deliver significant improvements, and optimized several operating parameters to ensure that it would all work together flawlessly. The new Third Generation represents a substantial improvement for our highly acclaimed XPA series of amplifiers – and delivers improvements in both technical performance and sound quality.
