Description

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

Standby	push button (halo ring changes color to indicate Standby or On).
Status LEDs	one per channel; blue. Status LEDs change to red to indicate a fault condition.

AC Power switch	rocker switch (switches the AC main power).
Status LEDs switch	disables front panel Status LEDs and dims Standby button halo.
Input selector switches (one per channel)	metal toggle switches; select between balanced and unbalanced inputs.
Circuit Breaker	press button to reset the circuit breaker.

Protection	The XPA-DR2 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions.
