• Fully balanced, fully differential, fully awesome.
• The centrepiece of a truly awesome two-channel system.
• The ultimate upgrade for the front two channels of a surround sound system.
• Pair with an XPA-5 or an XPA-7 for an incredible surround sound system.
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 that only a fully differential amplifier can provide.
The XPA-DR2 features two of Emotiva's 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 awesome surround sound music or home theatre 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.

Circuit Topology
Circuit Topology A fully modular, fully differential, fully balanced audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.
NOTE: This is a fully balanced amplifier with a floating, differential output stage. The output terminals must NEVER be tied together or ground-referenced. Doing so will cause immediate damage that is NOT covered under warranty. If you have any questions about speaker compatibility, please contact Emotiva for technical support.
