نظرة عامة

The XPA-DR2 is a fully balanced, fully differential two-channel power amplifier featuring two Differential Reference™ amplifier modules. Connect it to a stereo preamp, AV processor, or an AV receiver with preamp outputs, select balanced XLR or unbalanced RCA on each channel, and you are in business. Clean signal in, serious power out, with less strain on your system.

Inside, each channel uses a fully discrete, dual differential, high current, short signal path Class A/B output stage, backed by an Optimized Class H™ power supply topology and a high-efficiency SMPS. Protection is microprocessor-controlled, so it stays out of the way during normal listening but steps in fast when something is wrong.

Power (both channels driven): 550 W/ch into 8 ohms, or 800 W/ch into 4 ohms, at <0.1% THD.

Common uses:

• No-compromise two-channel systems with demanding speakers

• Front left and right channels in a serious home theater

• More headroom for cleaner dynamics at real listening levels

Important: This is a fully balanced amplifier with floating, differential outputs. Never tie output terminals together or reference them to ground.

Differential Reference™ Design
Our Differential Reference design uses a fully differential signal path, amplifying both halves of the audio signal separately to help reduce noise and distortion. The result is powerful dynamics, smooth detail, and natural imaging.
Pure Class A/B Sound
Designed for excellent sound with all types of music and systems, its low-noise, low-distortion Class A/B design delivers smooth, detailed performance without strain or harshness and remains stable with real-world speakers.
Efficient Power Delivery
Optimized Soft-Switch Class H™ power supply technology improves efficiency without sacrificing audio performance, while the SMPS delivers the performance of a traditional linear power supply with less weight and improved reliability.
Quality Construction
Built with high-quality parts for long-term reliability, the XPA-DR2 features a heavy steel 4RU chassis, milled aluminum faceplate, machined gold-plated RCA connectors, and modular construction that lets you add channels as your system grows. Designed, assembled, and tested in Franklin, Tennessee.
Flexible System Integration
Five-way binding posts support bare wire, lugs, and banana plugs, while each channel offers balanced or unbalanced inputs. Remote trigger connections, worldwide 100–250 VAC operation, and a standard IEC power inlet make integration simple in a wide range of systems.
Protection
Transparent fault protection helps protect the amplifier and connected equipment without affecting normal listening, while a resettable rear-panel circuit breaker provides additional protection from AC line faults. A five-year warranty adds long-term peace of mind.

CIRCUIT TOPOLOGY

CIRCUIT TOPOLOGY: A fully modular, fully differential, fully balanced audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.
NOTE: This is a fully balanced amplifier with a floating, differential output stage. The output terminals must NEVER be tied together or ground referenced. Doing so will cause immediate damage that is NOT covered under warranty. If you have any questions about speaker compatibility, please contact Emotiva for technical support.

AUDIO SPECIFICATIONS

AUDIO SPECIFICATIONS: The XPA-DR2 features two Differential Reference™ Amplifier Modules. Audio Specifications (Two Differential Reference Amplifier Modules):
Power Output (both channels driven): 550 watts RMS, per channel, into 8 Ohms, at <0.1% THD. 800 watts RMS, per channel, into 4 Ohms, at <0.1% THD.
Power Bandwidth (at rated power; 4 Ohm - 8 Ohm load): 20 Hz to 20 kHz (+ / – 0.1 dB).
Broad Band Frequency Response: 20 Hz to 50 kHz +0/-2 dB.
THD + noise: < 0.015%; at 100 watts RMS; 1 kHz; 8 Ohms.
Signal to Noise Ratio (8 Ohm load): > 120 dB; ref FTC rated power; unbalanced input (A-weighted). > 96 dB; ref 1 watt; unbalanced input (A-weighted).
Minimum Recommended Load Impedance (per channel): 4 Ohms. (which equals one 4 Ohm load or two paralleled 8 Ohm loads).
Damping Factor (8 Ohm load): > 500.
Input Sensitivity (for rated power; 8 Ohm load): 2.1 V.
Gain: 29 dB.
Maximum Power Consumption: 1,700 watts.
Note: The values shown refer to the amount of power the amplifier would consume while playing test tones continuously, on all channels, at full power, into a load bank. Therefore they are not at all characteristic of what you would expect when playing music or the sound track from a movie. Normal audio signals are dynamic, so the amount of power they require from second to second varies widely, and the average is far lower than this. With normal content, even playing very loudly, one of our amplifiers will consume far less power than indicated in the chart, so these values should not be considered to be a circuit requirement for normal operation.
Input Impedance: 33 kOhms (balanced). 23.5 kOhms (unbalanced).

INPUT & OUTPUT CONNECTIONS

Input Connections: Unbalanced (RCA); balanced (XLR); one each, per channel, user selectable.
Speaker Output Connections: Audiophile grade, gold plated, 5-way binding posts.

TRIGGER & POWER REQUIREMENTS

Trigger Input: 5 – 12 V (AC or DC); <10 mA input current required.
Trigger Output: 12 VDC; can drive any load up to 120 mA.
Power Requirements: Between 100 VAC and 250 VAC @ 50 / 60 Hz (automatically detected).

CONTROLS & INDICATORS
