One McIntosh MC501 monoblock amplifier. Used and in great condition. No box/manual so I can't ship it so I need to sell local to Seattle, WA area. Cash only at the time of pickup.
I changed from home theater to a 2 channel setup and need to sell this amp that was used for the center channel.
It has a good Stereophile review
Description: Solid-state monoblock power amplifier with balanced (XLR) and single-ended (RCA) inputs and "Autoformer"-coupled output stage.
Minimum sinewave continuous average power output: 500W into 8, 4, or 2 ohms (27dBW, 24dBW, 21dBW, respectively).
Rated power bandwidth: 20Hz-20kHz. THD: 0.005% into 8, 4, or 2 ohms, 250mW to rated power output.
IMD: 0.005% maximum if instantaneous peak output does not exceed twice the rated output for any combination of frequencies, 20Hz-20kHz, into 8, 4, or 2 ohms.
Dynamic headroom: 1.8dB. Wideband damping factor: 100 at 8 ohms (equivalent to a source impedance of 0.08 ohms)
Frequency responses: 20Hz-20kHz, +0/-0.25dB; 10Hz-100kHz, +0/-3dB.
Sensitivity: 2.1V unbalanced input, 4.2V balanced input. Signal/noise ratio: 97dB, A-weighted (124dB below rated output), unbalanced and balanced. Input impedance: 10k ohms unbalanced, 20k ohms balanced.
Dimensions: 17.5" W by 9.5" H (including feet) by 14 7/8" D (including front-panel knobs). Weight: 91.5 lbs (41.6kg)
