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)
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: –112dBV no signal, input shorted
Signal to noise: 115dB
Controls: Power on/off, auto shut-off on/defeat, Input BAL/SE, RS232, 12V trigger
Ambient air temperature: 30° C (86° F) maximum ambient air temperature
Power supply energy storage: Approximately 350 joules
Power requirements: 100-125VAC 60Hz (200-250VAC 50Hz) 410 watts at rated output, 500 watts maximum, 230 watts idle. Sleep power < 1 watt
Tubes required: 2 – Matched pair KT150 – Power Output; 2 – 6H30 Driver
