A:Answer Manufacturers often show a power output at very high distortion with only one or a few channels driven or at a single rather than the full audio band and into lower impedance loads to print a higher power output figure for marketing purposes. Here are the specs with different distortion levels and channels driven...
Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive) 75 W
Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive) 110 W
Power Output (6 ohm, 1 kHz, 10% 1ch Drive) 165 W
The more channels that are driven across the full audio band at low distortion levels, the lower the power will be.
