mc602 power amplifier see systems engineering in main brochure for more on mcintosh system architectures t he mc602 is the most powerful stereo amplifier ever produced by mcintosh it delivers 1.2 kilowatts of unrestrained power with the finesse of a dancer the double-balanced design ­ possible only with the exclusive mcintosh output autoformer ­ all but eliminates distortion if you can imagine a truck-pull contest using ferraris then you can appreciate the mc602 s capacity to astonish featured technologies double-balanced push-pull design the mc602 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 the bifilar winding technique used in the making of autoformers earned mcintosh one of its first patents the design is so advanced it is still used today dual power supplies each channel of the mc602 has its own power supply ensuring optimum performance 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 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.
