        Benefits of Emotiva XPA-DR1 Differential Reference™ Monoblock Power Amplifier:

        The Power Supply: The Foundation Of A Great Amplifier
        The Power Supply: The Foundation Of A Great Amplifier

        In the amplifier design, everything starts with the power supply. The XPA-DR1 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. 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, the 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, 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 Latest In A Long Line Of Great Amplifiers

        The Differential Reference Amplifier Modules that is used in 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 our new fully balanced, fully differential, XPA-DR amplifiers. Together they deliver a holistic, natural, and powerful listening experience.  

        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 fully analog Class A/B output stage, and 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. 

        Modular Construction
        Modular Construction

        Each XPA-DR Differential Reference Monoblock 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. (Because the XPA-DR1 is configured with a single Differential Reference Module, up to two additional modules can be added later).
