Power Output<\/span><\/td>\n750 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 750 watts, below .04% at 1 watt. Approximate actual power available at \u201cclipping\u201d 850 watts (1kHz). (Note that actual power output is dependent upon both line voltage and \u201ccondition\u201d i.e. if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)<\/span><\/td>\n<\/tr>\n
