SpecificationsPOWER OUTPUT150 watts per channel continuous from 20Hz to 20kHz. 1kHz POWER OUTPUT150 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 150 watts, below 0.03% at 1 watt. Approximate actual power available at ‘clipping’ 160 watts (1kHz). (Note that actual power output is dependent upon both line voltage and ‘condition’ i. e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)POWER BANDWIDTH(-3dB points) 5Hz to 80kHzFREQUENCY RESPONSE(-3dB points at 1 watt) 0.5Hz to 120 kHzINPUT SENSITIVITY2.0V RMS BAL for rated output.
