POWER OUTPUT
140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at
140 watts, below 0.04% at 1 watt. (Note that actual power output is dependent upon
both line voltage and “condition” ie: if power line has high distortion, maximum power
will be affected adversely, although from a listening standpoint this is not critical).
POWER BANDWIDTH
(-3dB Points) 5Hz to 70kHz.
FREQUENCY RESPONSE
(-3dB points at 1 watt) 0.5Hz to 110kHz.
INPUT SENSITIVITY
