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; 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: < 0.008%; 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).
