McIntosh MC352

All pre-owned product is tested in our service department and have been passed for sale... and comes with a 90 day warranty!  This checked out great! We replaced some of the bulbs.

In nice condition! Back panel has seen some wear- see pix. Pix with white backgrounds are stock. See last image for specs.

Original box and packing are NOT available, so this is LOCAL PICKUP ONLY...

BUT If you want us to ship this to you, please contact us if you would like to purchase at an additional cost (approx $100 plus shipping for the carton ONLY), a McIntosh factory box to safely ship it in. We will advise lead time and final price for the box at that time. This is the ONLY was we ship this unit because of the glass front.

DOUBLE-BALANCED PUSH-PULL DESIGN. The MC352 is fully balanced from input to speaker output. Matched amplifiers operate in complimentary push-pull with their outputs combined in the McIntosh autoformer. The resulting double-balanced configuration cancels virtually all distortion. This circuit design is possible only with the McIntosh autoformer.

EXCLUSIVE MCINTOSH OUTPUT AUTOFORMERS. An impedance mismatch between an amplifier and loudspeaker can cause distortion and a reduction in power. The legendary McIntosh autoformer is a hand-crafted transformer with output connections for 2, 4, and 8 ohms (plus 1, 2, and 4 ohms for the MC352’s mono parallel mode), allowing an ideal impedance match. A McIntosh amplifier with an autoformer can also safely drive multiple speakers connected in parallel without shortening the life expectancy of the output stage. There is absolutely no performance penalty with an autoformer. In fact, its frequency response exceeds that of the output circuit itself, and extends well beyond the audible range. Distortion is so low it is virtually immeasurable.

EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM. Power Assurance is a collection of technologies that enhance performance and reliability and protect the amp and the loudspeakers. Power Guard® clipping protection. Power Guard ensures that the amplifier will always deliver full power without causing clipping distortion. If an amplifier channel is overdriven, Power Guard automatically reduces the input volume just enough to keep distortion below 2% and prevent any clipping distortion. Thanks to an optical resistor, Power Guard acts literally at the speed of light, producing absolutely no audible side effects. An amplifier with Power Guard will actually deliver clipping-free output well above its rated power. Sentry Monitor® current protection. Sentry Monitor continually senses the voltage and current of the output stage and confines it to a safe limit. Sentry Monitor does not limit power output. Thermal Cutout. If the cooling air is blocked and the power transistors become too hot, thermal cutouts protect against overheating until the amp cools. DC Failure protection. In the rare event of an output circuit failure, any DC current that appears in the output is shunted to ground by the autoformer, protecting the speakers from damage. Turn-On Delay. This circuit delays operation for about two seconds after turn-on in order to avoid any pops or thumps generated as other equipment turns on. Soft Start inrush protection. Thermistors in the power transformer act as a cushion against inrush current, eliminating component stress during turn-on.

ILLUMINATED PEAK-RESPONDING WATTMETERS. The output in watts of any amp depends on loudspeaker impedance, which varies considerably with the frequency content of music. Conventional output meters may display “watts” but they actually measure output voltage because they assume a fixed impedance. McIntosh wattmeters display real output in watts, and thus indicate the real power required to drive a particular speaker. McIntosh wattmeters respond 95% full scale to a single-cycle tone burst at 2kHz. Response is almost 10-times faster than a professional VU meter. The “hold” feature provides a longer pause at the peak reading. The meter illumination can be switched off.

BALANCED CONNECTIONS. Balanced connections guard against induced noise. A balanced connection between the MC352 and the C42 Control Center provides 40dB more noise protection than would an unbalanced (“single-ended”) connection.

REMOTE POWER CONTROL. This allows a McIntosh Control Center to turn the MC352 and other system components on/off.
