The McIntosh MC-2100 is a solid state stereo power amplifier manufactured from 1969 to 1978. It delivers 105 watts per channel into 8 ohms in stereo mode and 210 watts into 8 ohms in mono mode. The amplifier features McIntosh's patented autoformers on the output stage, providing excellent bass response and dynamic drive. It has a frequency response of 20 Hz to 20 kHz with a total harmonic distortion of 0.25%. The amplifier is designed with a damping factor of 11 to 14 depending on speaker impedance, and an input sensitivity of 0.5 volts. It includes a Sentry Monitor protection circuit and is stable with any loudspeaker load or reactive load. The MC-2100 has a chrome and black chassis, weighs 57 pounds, and measures approximately 7.75 inches high, 11.75 inches wide, and 17 inches deep. It is highly regarded for its musicality, smooth midrange, and well-defined bass, often described as having a slightly warm character reminiscent of tube amplifiers. The amplifier requires 120 volts AC power and consumes 450 watts at rated output. It is no longer manufactured but remains a classic and sought-after vintage amplifier.
