Emotiva XPA-3 G3 3 Channel Power Amp
3 Channel 300W/Channel output
Modular design expands to more channels in the same chassis.

Class H power delivery of ultimate performance
The power amplifier performs the simple but critical job of boosting the output signals from each channel of your stereo preamp or surround sound processor to the level necessary to drive your loudspeakers. While this may seem trivial, a really good power amp is essential to having a great audio system, because any flaws in the performance of your power amp are going to limit the performance of your entire system.
Every amplifier in the new Third Generation XPA series was carefully designed to deliver superb technical performance, unsurpassed sound quality, and an exceptionally accurate and dynamic rendition of all types of music, thus ensuring that your entire system will sound its absolute best. Each individual XPA amplifier is modular, and can be customised to provide exactly the power and number of channels you need today, and expanded later if your needs change; and multiple matching chassis enable you to add even more channels, or more power, for a near-endless variety of options.
Class A/B Sound Quality Meets Optimized Class H Efficiency
The High-Powered Single Channel Modules used in the XPA-2 utilise a fully analogue Class A/B output stage, and our highly regarded Soft-Switch™ Optimized Class H power supply topology, which increases their efficiency significantly without compromising their superb Class A/B performance and sound quality. At low power levels, each channel operates on a relatively low supply voltage, to minimize quiescent power consumption and standby power losses. Then, when the demand for power increases, it instantly and seamlessly switches to a higher voltage rail to ensure that the signal passes cleanly and without clipping. This process happens on a continuous basis - in real-time, allowing greater overall efficiency, cooler operation, longer component life, reduced power consumption, and increased reliability.
