Description
XPA-DR1
• Finesse and power in the ultimate Emotiva monoblock.
• Fully balanced, fully differential, fully awesome.
• Use a pair to power the ultimate stereo system.
• Use a full set to create a truly ultimate surround sound experience.
The XPA-DR1 is a true monoblock power amplifier and features a single Differential Reference Amplifier Module, in a true monoblock configuration, powered by its own dedicated 3 kW switch mode power supply. The XPA-DR1 provides massive power, superb dynamics, incredible resolution, and absolute control. If you’re looking for the very best sound quality, with virtually endless reserves of power against a jet-black noise floor, this is the amplifier for you.
The XPA-DR1 delivers 650 watts RMS into 8 Ohms, and 1000 watts RMS (that’s 1 kW) into 4 Ohms, 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. |
