Based, like the monumental MC2KW, on McIntosh 's exclusive Quad Balanced architecture, the MC1.25KW monophonic transistor power stage is one of the most advanced and exclusive amplifiers on the world market.
Completely redesigned from the venerable MC1.2KW, the MC1.25KW is McIntosh 's most exclusive monophonic power amplifier mounted on a single chassis - its almost 72 kilos of weight speak loud and clear in this regard. Thanks to the exclusive Autoformer technology of the American firm, it delivers a total of 1,200 continuous watts to loads of 8, 4 or 2 ohms with practically negligible distortion, while introducing such relevant improvements with respect to its predecessor as it is. The 50% increase in filtering capacity allows it to display dazzling records in parameters such as low end reproduction and dynamic range.
Regarding its industrial design, the MC1.25KW includes the aforementioned Autoformer and the power transformer just behind the front panel (as has been the norm at McIntosh for decades), although mounted in newly designed enclosures with a top panel of glass to enhance the overall beauty of the whole.
Another key element of the MC1.25KW's exterior are the four McIntosh exclusive Monogrammed Heatsinks heatsinks it features, made from high-quality materials and selected for their exceptional thermal conductivity. Connected to sophisticated high-current output transistors that eliminate waiting time to reach thermal equilibrium, these heatsinks are covered with ventilation trim plates made of aluminum that match the aluminum trim ring on the top panel.
The MC1.25KW also includes the effective Power Guard system to prevent possible clipping/clipping of the audio signal from damaging the loudspeakers, as well as the Sentry Monitor, an extremely fast protection circuit that deactivates the output stage. to prevent the current from exceeding safe operating limits.
As is the tradition at McIntosh , the MC1.25KW is crowned by the unmistakable treated glass front panel and one of the brand's legendary analogue vu meters with a blue background.
