Introducing the new XPA Gen3 Modular Amplifier System, now with a compact 15" chassis designed to fit most modern home entertainment cabinets. Our innovative design allows you to mix and match mono and stereo modules within the 5 available bays, giving you the flexibility to configure the perfect amplifier for your needs. Whether you choose one of our popular pre-configured models or create a custom setup, the XPA Gen3 delivers exceptional technical performance and superb sound quality for both music and movie soundtracks in high-end home theater systems.

Each XPA C Gen3 chassis can accommodate between 1 to 5 modules, allowing for a combination of High-Powered Single Channel Modules and Stereo Modules. This modular approach provides unmatched flexibility, enabling you to build the exact amplifier configuration you need. Use our Channel Configuration selector to choose your ideal combination, with model numbers indicating the number of mono and stereo modules included.

The Power Supply: The Foundation of a Great Amplifier

At the heart of the XPA Gen3 is our new high-current switch mode power supply (SMPS), capable of delivering over 3 kW of continuous power with high efficiency and reliability. This advanced SMPS offers the dynamic attributes of classic transformer-based designs without the drawbacks, ensuring ample continuous and dynamic power for all amplifier modules.

The Latest in a Long Line of Great Amplifiers

The XPA Gen3 features a unique differential input stage with cross-linked current sources driving a balanced voltage amplification stage. This advanced circuitry ensures an accurate and pure audio signal, delivering a holistic, natural, and powerful listening experience. The wide bandwidth and low distortion performance reveal every nuance of high-resolution music sources, providing enough power to drive even the most demanding loudspeakers.

Class A/B Sound Quality Meets Optimized Class H Efficiency 

Both amplifier modules in the XPA Gen3 utilize a fully analog Class A/B output stage powered by the Soft-Switch™ Class H power supply topology, enhancing efficiency without compromising audio quality. The Mono modules and Stereo Modules deliver independent channels of pure Class A/B audio power, perfectly matching the performance of each module.

The Benefits of a Dedicated Power Amplifier

Our dedicated power amplifiers, designed for single-purpose use, avoid the compromises inherent in multi-purpose components. The result is real-world power and fidelity that you can immediately hear and appreciate. The 3 kW switch mode power supply ensures tightly regulated continuous power and massive reserves of dynamic power, enabling our amplifier modules to perform to their ultimate potential.

Designed and Assembled in the USA with Globally Sourced Components

Designed, assembled, and tested in the USA, the XPA Gen3 uses premium components to deliver a reliable and refined system. Each amplifier is crafted with the finest materials and the latest technologies, embodying our commitment to world-class audio performance.

A new approach to amplifier design

With the XPA C Gen3, we've taken amplifier design to a new level. By analyzing and improving every aspect of our previous models, we have created a foundation for our new line of audiophile amplifiers. The XPA Gen3 is a modular power amplifier housed in a heavy-duty chassis, featuring an oversized power supply and up to five amplifier modules. As your needs grow, additional modules can be installed to expand the system, ensuring you always have the perfect configuration.

Note: For optimal performance and reliability, amplifier modules need to be installed by Emotiva or an authorized Emotiva service representative.
