McIntosh MAC-4200
Official sources say little about the McIntosh MAC-4200, but period magazine listings fill in the outline of a substantial late-1980s AM/FM receiver. HiFi/Stereo (February 1987, p.78) listed it as a 75-watt-per-channel (8 ohms) model with inputs for two tape decks, TV/AUX I, CD/AUX 2, and two turntables, plus front-panel tape jacks. A later listing in the same publication (1988, p.52) gave more detail: 100 W/ch into 4 ohms, 75 W/ch into 8 ohms, 54 lb, and a price of $2,890.
The receiver had switchable IF bandwidth, 7 AM and 7 FM presets, and a high-blend feature. The 1988 listing shows no more than 0.1% THD into 8 ohms, dynamic headroom of 1.5 dB, and 200-ms dynamic power of 64 watts. The FM section delivered 74 dBA S/N at 65 dBf, stereo THD of 0.07%, a capture ratio of 2 dB, and alternate-channel selectivity of 55 dB. Earlier figures from 1987 give a slew rate of 50 V/µs, rise time of 1.0 µs, and IHF-A signal-to-noise ratios of 64 dB (phono MC), 82 dB (phono MM), and 100 dB (high-level inputs).
The MAC-4200 appears to have been McIntosh's top-tier receiver in the late 1980s. Beyond these period listings, little else survives in the documentary record.
