Specifications
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.)
INPUT IMPEDANCE: 300K ohms Balanced (150K ohms SE)
OUTPUT POLARITY: Non-inverting. Balanced input pin 2+ (IEC-268)
