MC1201
Monoblock Power Amplifier

Producing a massive 1,200 watts, the MC1201 is one of the most powerful amplifiers ever created by McIntosh Laboratory. The extraordinary quaddifferential design of the MC1201 actually consists of two complete amplifier circuits, one the mirror image of the other, whose outputs are combined in the unique McIntosh Output Autoformer, resulting in totally balanced operation from input to speaker output and the cancellation of virtually all distortion.

 

The McIntosh Autoformer, a hand-crafted transformer with output connections for two, four and eight ohms, creates an ideal impedance match to guard against distortion and reduction in power. A McIntosh amplifier with an Autoformer can also safely drive multiple speakers connected in parallel, without shortening the life expectancy of the output stage. Far from exacting any performance penalty, the Autoformer’s frequency response exceeds that of the output circuit, and extends well beyond the audible range, for almost immeasurably low distortion.
