Emotiva XPA-DR2 Differential Reference Two-Channel Power Amplifier
The Emotiva XPA-DR2 is a two-channel audiophile power amplifier built on a fully differential, fully balanced architecture: each channel’s signal path is balanced from input to output, which cancels noise and distortion in a way single-ended designs cannot. Its two Differential Reference amplifier modules deliver 550 watts RMS per channel into 8 ohms and 800 watts into 4 ohms, both channels driven, at under 0.1% THD. The chassis is modular — a third module can be added later by an authorised installer if the system grows to three channels.
Key features
550 W RMS per channel into 8 ohms; 800 W into 4 ohms
Discrete dual-differential Class A/B amplifier modules
Optimised Class H switch-mode power supply, over 3 kW capability
THD+N under 0.008% at 100 W, 1 kHz, 8 ohms
Balanced XLR and unbalanced RCA inputs per channel
Modular chassis — third channel can be added
Differential Reference design
In a fully differential amplifier, each channel carries the signal as a balanced pair through the entire amplifier, so interference and even-order distortion generated inside the amp are cancelled at the output. Emotiva’s Differential Reference modules implement the input and driver stages as discrete, dual-differential, short-signal-path circuits rather than op-amp blocks, and the output stage runs traditional Class A/B for its smooth overload behaviour. Damping factor exceeds 500, keeping control of woofer motion with demanding speakers.
The power supply
Amplifiers are limited by their supplies, and the XPA-DR2’s is a high-current switch-mode design configured for over 3 kW of continuous delivery, regulated so output does not sag with line voltage or load. An Optimised Class H rail-tracking topology raises efficiency — the supply follows the signal’s demands instead of dissipating the difference as heat — which is how this much power fits in a standard-width chassis. Maximum consumption under full test load is 1,700 W; normal music listening draws a fraction of that.
Measured performance
Power bandwidth is 20 Hz to 20 kHz within +/-0.1 dB at rated power; broadband response extends to 50 kHz. Signal-to-noise ratio exceeds 120 dB referenced to rated power (A-weighted). Input sensitivity is 2.1 V for rated output with 29 dB of gain, matching typical preamplifier and processor outputs, and minimum recommended load is 4 ohms per channel.
Connections and protection
Each channel offers balanced XLR and unbalanced RCA inputs selected by a metal toggle switch, gold-plated five-way binding posts for speaker cables, and 12 V trigger input and output for system power sequencing. Microprocessor-supervised protection guards against temperature, shorted outputs and ground faults while remaining transparent in normal use, and a resettable rear-panel breaker protects the AC side. The amplifier accepts any line voltage from 100 to 250 VAC.
