The XPA-3 Gen3 delivers 275 Watts RMS x 3 into 8 Ohms with all channels driven (and 300 Watts RMS into 8 Ohms or 490 Watts RMS into 4 Ohms with two channels driven); and, because it’s modular, you can add up to four additional amplifier modules to the XPA-3 Gen3 when you decide you need them.\u003c\/p\u003e\n\u003ch4\u003eThe Power Supply: The Foundation Of A Great Amplifier\u003c\/h4\u003e\n\u003cp\u003eIn amplifier design, everything starts with the power supply. The XPA-3 Gen3 features our new high-current switch mode power supply (SMPS) - a lightweight, powerful, intelligent design capable of delivering over 3 kW of continuous power with absolute reliability and extremely high efficiency. Our cutting edge SMPS offers the dynamic attributes of a classic transformer-based design with none of the drawbacks. Like the best transformer-based power supplies, our SMPS delivers plenty of continuous power to enable our amplifier modules to live up to their full performance potential, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited. However, compared to transformer-based designs, our SMPS is lighter and more efficient; it’s also fully regulated, which ensures optimum performance under a wider range of load conditions.\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003ch4\u003e\u003cspan\u003eCircuit Topology\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eThe XPA-3 Gen3 is a fully modular 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.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThe XPA-3 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAudio Specifications\u003c\/h4\u003e\n\u003cp\u003eThe XPA-3 Gen3 features three of our High-Powered Single Channel Modules.  \u003c\/p\u003e\n\u003ch4\u003eAudio Specifications (Three High-Powered Single Channel Modules):\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003ePower Output:\u003cbr\u003e300 watts RMS\/channel;

Emotiva XPA-3 Gen3 Home Theatre Power Amplifier

Product Description
R 32,990.00
Maximum quantity available reached.

The Emotiva XPA-3 Gen3 is a three-channel audiophile power amplifier. The XPA-3 Gen3 offers excellent technical performance, and an exceptionally accurate and dynamic rendition of all types of music.

The XPA-3 Gen3 features three of our High-Powered Single Channel Modules – for a total of three high-powered channels, which makes it the ideal choice to power the three important front channels in a great sounding home theater or surround sound music system. The XPA-3 Gen3 delivers 275 Watts RMS x 3 into 8 Ohms with all channels driven (and 300 Watts RMS into 8 Ohms or 490 Watts RMS into 4 Ohms with two channels driven); and, because it’s modular, you can add up to four additional amplifier modules to the XPA-3 Gen3 when you decide you need them.

The Power Supply: The Foundation Of A Great Amplifier

In amplifier design, everything starts with the power supply. The XPA-3 Gen3 features our new high-current switch mode power supply (SMPS) - a lightweight, powerful, intelligent design capable of delivering over 3 kW of continuous power with absolute reliability and extremely high efficiency. Our cutting edge SMPS offers the dynamic attributes of a classic transformer-based design with none of the drawbacks. Like the best transformer-based power supplies, our SMPS delivers plenty of continuous power to enable our amplifier modules to live up to their full performance potential, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited. However, compared to transformer-based designs, our SMPS is lighter and more efficient; it’s also fully regulated, which ensures optimum performance under a wider range of load conditions. 

Circuit Topology

  • The XPA-3 Gen3 is a fully modular 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.

  • The XPA-3 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).
