Specifications
Power Output:
75 watts per channel
continuous from20Hz to 20kHz. 1kHz
total harmonic distortion typically 0.6%
at 75 watts, below 0.05% at 1 watt.
Approximate actual power available at
‘clipping’ 76 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)
7Hz to 60kHz
Frequency Response:
(-3dB points
at 1 watt) 0.7Hz to 75 kHz
Input Sensitivity:
1.4V RMS BAL for rated
output. (25 dB Bal gain into 8 ohms)
Input Impedance: 300K ohms Balanced
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
Hum & Noise: Less than 0.06mV
RMS – 112dB below rated output
(IHF weighted, input shorted)
Power Supply Energy Storage:
