POWER OUTPUT: 50 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1% at 50 watts, below .05% at 1 watt.
Approximate actual power available at “clipping” 52 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) 12Hz to 90kHz.
FREQUENCY RESPONSE: (-3dB points at 1 watt) 1.0Hz to 100 kHz.
INPUT SENSITIVITY: 0.5V RMS Single-ended for rated output. (32dB gain into 8 ohms.)
INPUT IMPEDANCE: 50K ohms Single-ended.
INPUTS (5): CD, Tuner, Video, SE1, SE2 (Single Ended RCA connectors).
MAXIMUM INPUT: 3.5V RMS (any input). Optional 6dB pad for CD input.
OUTPUT POLARITY: Non-Inverting (any input).
PUSH BUTTONS: Volume up, Volume down. (70 steps, 20 LED indicators), Input, Mono, Mute, Power. All functions on IR remote control.
OUTPUT TAPS: 8 ohms, 4 ohms.
OUTPUT REGULATION: Approximately 1.5dB 8 ohm load to open circuit (Damping factor approximately 5).
MONO SUBWOOFER OUTPUT: 1V RMS at rated power.
OVERALL NEGATIVE FEEDBACK: 10dB.
SLEW RATE: 10 volts/microsecond.
RISE TIME: 2 microseconds.
HUM & NOISE: Less than 0.14mV RMS – 103dB below rated output (IHF weighted, input shorted).
POWER SUPPLIES: Electronically regulated Low and High voltage supplies for input stages. Automatic 30 sec. warm-up/brown-out mute.
POWER SUPPLY ENERGY STORAGE: Approximately 166 joules.
POWER REQUIREMENTS: 100-125VAC 60Hz (200-250VAC 50Hz) 320 watts at rated output, 500 watts maximum, 205 watts at “idle”. 0.5 watts power off.
TUBES REQUIRED: 2 – Matched pair 6550EH – Power Output; 3 – 6N1P input and driver.
