Emotiva XPA-DR1 Differential Reference™ Monoblock Power Amplifier

• Finesse and power in the ultimate Emotiva monoblock.
• Fully balanced, fully differential, fully awesome.
• Use a pair to power the ultimate stereo system.
• Use a full set to create a truly ultimate surround sound experience.

The XPA-DR1 is a true monoblock power amplifier and features a single Differential Reference Amplifier Module, in a true monoblock configuration, powered by its own dedicated 3 kW switch mode power supply. The XPA-DR1 provides massive power, superb dynamics, incredible resolution, and absolute control. If you’re looking for the very best sound quality, with virtually endless reserves of power against a jet-black noise floor, this is the amplifier for you.

The XPA-DR1 delivers 650 watts RMS into 8 Ohms, and 1000 watts RMS (that’s 1 kW) into 4 Ohms, 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-DR1 features a custom-configured version of the 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. Emotiva's 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 the 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, the 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 the 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 the 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 and low distortion performance of the XPA-DR1 reveal 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™ Module in the XPA-DR1 utilizes a matched pair of amplifier modules, each of which features Emotiva's fully analogue Class A/B output stage, and their 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 continuously 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 Emotiva's power amplifiers are designed for a single purpose, they 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 Module in the XPA-DR1 is made up of a perfectly symmetrical balanced pair of high-performance amplifier modules. Each 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, Emotiva can achieve even lower levels of distortion in the XPA-DR1, resulting in remarkably transparent sound, with unprecedented smoothness and clarity.

Finally, because the XPA-DR1 is a true monoblock, and only contains a single power supply and amplifier channel, even the slightest possibility of interaction between channels is eliminated, ensuring the best possible isolation between channels, and perfect channel separation. When you put it all together, the XPA-DR1 is simply the finest amplifier Emotiva can devise, and we’re sure you’ll be as impressed with its performance.

Designed and Assembled in the USA with Globally Sourced Components
The XPA-DR1 is designed, assembled, and tested in the USA, where Emotiva uses 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.

A new approach to amplifier design
When Emotiva set out to make the new X Series line, they analysed everything in every amplifier they’ve ever made, from front to back, inside, and out. In doing so, they discovered several areas where their years of experience, and advances in audio technology, indicated that they could make significant improvements in their amplifier designs. After carefully weighing all the pros and cons, Emotiva kept the best features of its original designs, added a new set of optimizations and improvements, and the result became the foundation of its new line of audiophile amplifiers. The new XPA-DR amplifiers are the fully differential members of the new XPA amplifier family and carry Emotiva's philosophy of continuous product improvement to its ultimate conclusion.

Modular Construction
Each XPA-DR Differential Reference Monoblock Power Amplifier is comprised of a heavy-duty chassis, which houses the 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. (Because the XPA-DR1 is configured with a single Differential Reference Module, up to two additional modules can be added later.)
