Emotiva XPA-4 Gen3 4 Channel Power Amplifier

Thanks to the Regulated Switch Mode Power Supply (SMPS) power supply it offers all of the benefits of a classic transformer-based design, but avoids virtually all of the limitations. It can deliver over 3 kW of fully regulated power, which ensures optimum performance under a wide range of load conditions, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited.

Perfect for powering:

All 4 main channels in a superb 7.1 channel home theater system

A high-end 2 channel system with bi-amped front speakers

The 4 main channels in an Atmos or DTS-X system
Configuration:
4 x High-Powered Single-Channel Modules (all slots populated)

Power output:
Power Output: 300 watts RMS/channel; 20 Hz – 20 kHz; THD<0.1%; 8 Ohms; one channel driven.

amplifier was designed first and foremost to sound superb in all types of audio systems.
• Great sounding Class A/B output stage - ensures smooth detailed sound and incredibly
natural imaging - without a trace of harshness or strain.
• Optimized Class H™ power supply topology - delivers improved efficiency without
compromising audio performance.
• Switched Mode Power Supply (SMPS) - offers all of the performance of a traditional linear
power supply, while improving efficiency and reliability, and reducing overall weight.
• Fully modular construction - allows you to purchase as many channels as you need today,
then add more channels later when and if you need them.
• Top quality parts and construction throughout - promise years of reliable service.
• Totally stable - designed for use in the real world, with real speakers.
• Heavy steel 4RU chassis with milled aluminum face plate - provide strength and rugged
good looks.

100 VAC and 250 VAC; and is protected from faults by a rugged resettable circuit breaker.
• Standard IEC power inlet - fits all standard and audiophile IEC power cables.
• Fully five year warranty - ensures that you’ll be able to enjoy your XPA Gen3 amplifier for
years to come.

Class A/B Sound Quality Meets Optimized Class H Efficiency
The High-Powered Single Channel Modules used in the XPA-4 utilize a fully analog Class A/B output stage, and our highly regarded Soft-Switch™ Optimized Class H power supply topology, which increases their efficiency significantly without compromising their superb Class A/B performance and sound quality. At low power levels, each channel operates on a relatively low supply voltage, to minimize quiescent power consumption and standby power losses. Then, when the demand for power increases, it instantly and seamlessly switches to a higher voltage rail to ensure that the signal passes cleanly and without clipping. This process happens on a continuous basis - in real time, allowing greater overall efficiency, cooler operation, longer component life, reduced power consumption, and increased reliability.
