PRODUCT DETAILS
Technical 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 the 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)
OUTPUT TAPS- 8 ohms, 4 ohms
OUTPUT REGULATION- Approximately 1.0dB 8 OHM LOAD TO OPEN CIRCUIT (Damping factor approximately 8)
OVERALL NEGATIVE FEEDBACK- 15dB
SLEW RATE- 10 volts/microsecond
RISE TIME- 4.0 microseconds
CHANNEL SEPARATION- 112dB
HUM & NOISE- –84dBV weighted, 8 ohms tap
SIGNAL TO NOISE- 112dB
CONTROLS- Power on/off, auto shut-off on/defeat, Input BAL/SE, RS232, 12V trigger
