The XPA-DR3 is a high-powered three-channel audiophile power amplifier that combines the exceptional accuracy and finesse of a true balanced differential design with the power you need to deliver musical crescendos and movie special effects with stunning realism and impact. Whatever your listening preferences, the XPA-DR3 will give you the combination of detail and power than only a fully differential amplifier can provide.
The XPA-DR3 features three of Emotiva’s 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. The 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, Emotiva’s SMPS delivers plenty of continuous power to enable their 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, Emotiva’s SMPS is lighter and more efficient; it’s also fully regulated, which ensures optimum performance under a wider range of load conditions.
The Latest In A Long Line Of Great Amplifiers
The Differential Reference Amplifier Modules Emotiva use in their XPA-DR amplifiers use the same basic circuit topology as Emotiva’s legendary XPR series amplifiers. A unique differential input stage, with a cross-linked current source, drives a balanced voltage amplification stage, and this advanced input circuitry delivers an incredibly accurate and pure audio signal to the complementary, fully discrete output stage. A pair of these modules work together in perfect synergy to power a single channel of one of our new fully balanced, fully differential, XPA-DR amplifiers. Together they deliver a holistic, natural, and powerful listening experience. Low-level musical details and dialogue emerge from a deep black background; musical crescendos are delivered with both stunning impact and precision. The wide bandwidth, low distortion performance of the XPA-DR3 reveals every nuance of your high-resolution music sources, and it has plenty of power to drive even difficult loudspeakers with absolute authority and control.
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.
The Benefits Of A Fully Differential Balanced Power Amplifier
Most experts agree that, if you want the absolute best sound quality and technical performance, you should use dedicated separate components. Because our power amplifiers are designed for a single purpose, we can concentrate on ensuring that they perform that one task very well, and avoid the compromises inherent in products that are expected to perform a variety of different functions.
The Differential Reference Modules in the XPA-DR3 are each made up of a perfectly symmetrical balanced pair of high-performance amplifier modules. Each individual amplifier module already has vanishingly low distortion but, by connecting them as a balanced differential pair, a significant portion of the tiny amount of remaining nonlinearity is cancelled out. As a result, we are able to achieve even lower levels of distortion in the XPA-DR2, resulting in remarkably transparent sound, with unprecedented smoothness and clarity.
When you put it all together, the XPA-DR3 is simply the finest three-channel amplifier we can devise, and we’re sure you’ll be as impressed with its performance as we are.
Designed and Assembled in the USA with Globally Sourced Components
The XPA-DR3 is designed, assembled, and tested in the USA, where we use the finest materials and latest technologies to bring you world-class products. Each Emotiva amplifier is carefully designed with premium components to deliver a stunningly capable, reliable, and refined system.
Latest and Greatest
A new approach to amplifier design.
When we set out to make the new X Series line, we analyzed everything in every amplifier we’ve ever made, from front to back, inside, and out. In doing so, we discovered several areas where our years of experience, and advances in audio technology, indicated that we could make significant improvements in our amplifier designs. After carefully weighing all the pros and cons, we kept the best features of our original designs, added a new set of optimizations and improvements, and the result became the foundation of our new line of audiophile amplifiers. The new XPA-DR amplifiers are the fully differential members of our new XPA amplifier family, and carry our philosophy of continuous product improvement to its ultimate conclusion.
Each XPA-DR Differential Reference™ Power Amplifier is comprised of a heavy-duty chassis, which houses our massively overdesigned, fully regulated, 3 kW switch mode power supply, and up to three Differential Reference™ Amplifier Modules. The front panel display and protection system are designed to work with the maximum number of channels, and so need not be updated when the XPA-DR is expanded; on the rear panel, slots not occupied by amplifier modules will be covered with protective cover panels. (The XPA-DR3 is configured with a full complement of three Differential Reference Modules already installed.)
Note: To ensure that amplifier channels are always installed properly, and function to Emotiva’s specifications, amplifier modules must be installed by Emotiva, or by authorized Emotiva service representatives.
