MC462 Power Amplifier
The MC462 replaces the highly regarded MC452 as the most powerful McIntosh stereo amplifier.
Experience stereo bliss with the MC462 Amplifier. Like the MC452, it features a robust output of 450 Watts per channel. With a dedicated McIntosh Autoformer™ connected to each audio channel, the full 450 Watts is available to any speaker regardless if it has 2, 4 or 8 Ohm impedance. Just one MC462 Amplifier can single-handedly power a world class home audio stereo system.
The new generation MC462 stereo amplifier has received numerous updates compared to the previous model. The most prominent is that filter capacity has been increased by nearly 50%, which has resulted in a remarkable 66% increase in dynamic headroom from 1.8dB to 3.0dB. This allows the MC462 to easily handle drastic swings in dynamics and effortlessly reproduce your favourite music with virtually no distortion. Bass performance is also improved as a result of the filter capacity increase. Our eco-friendly power management system, which will turn the amplifier off after a set amount of time when no input signal has been detected, has been added. Internal wiring and select circuit components have also been upgraded.
Aesthetically, the MC462 retains all the hallmarks of a McIntosh amplifier with a few key modern enhancements. The front panel now utilises direct LED backlighting that improves appearance and colour accuracy. The two audio Autoformers and single power transformer are housed in new enclosures topped by a single machined cover with glass inserts. The back half of the amplifier is home to four of the Monogrammed Heatsinks™ which connect to advanced high current output transistors that help eliminate thermal equilibrium lag time.
The balanced and unbalanced outputs make bi-amping or tri-amping your speakers easier; they can also be used to send the audio signal to a secondary system if your preamplifier does not have enough outputs, or to connect a powered subwoofer. The MC462 sits on a beautiful polished stainless steel chassis and features the timeless McIntosh black glass front panel, illuminated logo, control knobs, aluminium handles and a pair of fast responding blue Watt meters.
