EMOTIVA XPA DR3 GEN3 3-CHANNEL POWER AMPLIFIER
The immensely powerful 450wpc EMOTIVA XPA DR3 GEN3 3-channel power amplifier is a Class H based power amplifier providing three channels of amplification ideal for driving a set of left/centre/right speakers in a home theatre system.
The XPA-DR3 features three of our 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 theater 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.
The Power Supply: The Foundation Of A Great Amplifier
In amplifier design, everything starts with the power supply. The XPA-DR3 features a custom-configured version of our 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.
Class A/B Sound Quality Meets Optimized Class H Efficiency
The Differential Reference™ Modules in the XPA-DR3 each use utilize a matched pair of amplifier modules, each of which features our fully analog Class A/B output stage, and our highly regarded Soft-Switch™ Class H power supply topology, which increases their efficiency significantly without compromising the audio performance you’d expect from an Emotiva amplifier. The output stage in each operates on a lower supply voltage at low power levels to minimize quiescent power consumption and standby power losses, instantly switching to a higher voltage rail when needed to ensure 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.
