  • 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
