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: Approximately 520 joules
Power Requirements: 105-125VAC 60Hz (210-250VAC 50Hz)
410 watts at rated output, 500 watts
maximum, 230 watts idle
