Amplificator de putere Audio Research Reference 110 High Definition. Fabricate in SUA.
Stereo tubed power amplifier with balanced inputs and 4, 8, and 16 ohm output transformer taps.
Tube complement: 4 matched pairs of 6550C output tubes, 4 6H30 driver tubes.
Maximum output power:
110W pc continuous, 20Hz–20kHz at 1kHz with THD typically 0.3% at 110W, <0.03% at 1W;
120W at clipping (20.8dBW).
Frequency response: 0.6Hz–90kHz, –3dB. Input sensitivity: 1.8V RMS balanced for rated output (24dB balanced gain into 8 ohms).
Input impedance: 300k ohms balanced.
Output polarity: non-inverting.
Damping factor: approximately 12. Hum & noise: <0.2mV RMS, 106dB below rated output (IHF weighted, input shorted).
Power requirements: 105–125VAC, 60Hz (210–250VAC, 50Hz), 630W at rated output, 800W maximum, 410W at “idle.”
Dimensions: 19″ (483mm) W by 8.75″ (222mm) H by 19.5″ (495mm) D. Handles extend 1.5″ (38mm) forward.
