ULTIMATE POWER
The reference level McIntosh MC2.1KW Monoblock Power Amplifier is the ultimate power in home audio amplification. Our 75+ years of experience as the leader of sound reproduction has led us to the MC2.1KW. The pinnacle of audio amplification, the MC2.1KW stands as a testament to our unwavering commitment to sonic perfection. This tri-chassis marvel possesses the remarkable ability to deliver an astonishing 2,000 Watts of pristine McIntosh power, forever transforming your home stereo or theater experience. At McIntosh, we don't just appreciate sound – we are made of sound. The MC2.1KW is the embodiment of our passion, and it invites you to embark on an extraordinary journey through sound.
Available separately or as part of our Reference Music System and Reference Home Theater System, the MC2.1KW pairs seamlessly with our XRT2.1K Loudspeaker or its predecessor, the XRT2K. However, its versatility knows no bounds and it's not limited to just being used with McIntosh speakers but instead can be used with a wide variety of other speakers. It is ideally suited for audio systems that have power hungry loudspeakers; systems located in extremely large rooms; or for audio enthusiasts who simply demand the latest and best in state-of-the-art home audio amplification.
SYMPHONY OF TECHNOLOGY
The MC2.1KW consists of three separate modules: one Output Module and two Power Modules that each contain a 1,000 Watt amplifier. The incoming audio signal enters the Output Module from the preamplifier. An in-phase signal is sent from the Output Module to one of the Power Modules and is amplified. At the same time, an out-of-phase signal is sent to the other Power Module and amplified. Both amplified signals exit the Power Modules and reenter the Output Module where they drive opposite ends of the bi-filar wound McIntosh Autoformer™. This combines the two audio signals back into one with the power summed while any noise is reduced or completely canceled. Through this artful engineering, a low distortion audio signal leaves the Output Module to deliver pristine sound through your speaker.

FULL POWER WITH NO SACRIFICES
Thanks to our hand wound Autoformer, the full 2,000 Watts of power can be delivered into a speaker regardless if its impedance is 2, 4 or 8 Ohms. This means you won't need to sacrifice any power if your speaker impedance doesn't match the amplifier's output impedance. That's because amplifiers from most other brands only have one output impedance and if that doesn't match your speaker's impedance, then you could sacrifice up to half of the amplifier's power capabilities. This will not happen with our Autoformer and its unique ability to output full power at three separate impedances.
