POWER OUTPUT
75 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 75 watts, below 0.05% at 1 watt. (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) 7Hz to 60kHz.
FREQUENCY RESPONSE
(-3dB points at 1 watt) 0.7Hz to 80kHz.
INPUT SENSITIVITY
1.4V RMS BAL for rated output. (25dB Bal gain into 8 ohms.)
