McIntosh MC352 2 Channel Power Amplifier for sale in Sarasota, FL
Possessing the legendary might of its forebears, the double-balanced MC352 attains a new level of refinement. Its high current output will drive any loudspeaker system to ultimate performance. Sonically transparent and lightning fast, the sound of the MC352 is simply the sound of music. 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. 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.
