Emotiva XPA DR2 - Differential Reference Two Channel Power Amplifier
The XPA-DR2 is a high-powered two-channel audiophile power amplifier that combines the exceptional accuracy and finesse of a true balanced differential design with the power you need to deliver musical crescendos and movie special effects with stunning realism and impact. Whatever your listening preferences, the XPA-DR2 will give you the combination of detail and power than only a fully differential amplifier can provide.
The XPA-DR2 features two of our Differential Reference™ Amplifier Modules, and is the ideal choice to power a no-holds-barred stereo music system, or to power the critical front left and right channels of an absolutely awesome surround sound music or home theater system. The XPA-DR2 delivers 550 watts RMS into 8 Ohms, and 800 watts RMS into 4 Ohms, both channels driven, with less than 0.1% THD.
Class A/B Sound Quality Meets Optimized Class H Efficiency
The Differential Reference™ Modules in the XPA-DR2 each use utilize a matched pair of amplifier modules, each of which features our fully analog Class A/B output stage, and our highly regarded Soft-Switch™ Class H power supply topology, which increases their efficiency significantly without compromising the audio performance you’d expect from an Emotiva amplifier. The output stage in each operates on a lower supply voltage at low power levels to minimize quiescent power consumption and standby power losses, instantly switching to a higher voltage rail when needed to ensure 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.
