• Fully balanced, fully differential, fully awesome.
• The ultimate choice for the front three channels of a surround sound system.
• Pair with an XPA-4 for a powerful 7.1 channel system.
• A great way to improve the performance of a really high-end AVR.
The XPA-DR3 is a high-powered three-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-DR3 will give you the combination of detail and power than only a fully differential amplifier can provide.
The XPA-DR3 features three of Emotiva’s Differential Reference™ Amplifier Modules and is the ideal choice to power the critical front three channels of an absolutely awesome surround sound music or home theatre system. The XPA-DR3 delivers 450 watts RMS into 8 Ohms, and 600 watts RMS into 4 Ohms, all three 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.
