Our techs have confirmed it's in perfect working condition and have installed a new matched quad set of Electro-Harmonix 6550 tubes in the output section. POWER OUTPUT: 50 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1% at 50 watts, below. Approximate actual power available at clipping 52 watts (1kHz).
Note that actual power output is dependent upon both line voltage and condition i. 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. 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. 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. DIMENSIONS: 14" (35.6 cm) W x 8" (20.3 cm) H x 16 (40.6 cm) D. (15.5 kg) Net; 40 lbs. Decibel Audio is a retail store and custom installation business in the Wicker Park neighborhood of Chicago.
