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.

Why are there three modules instead of one? There are two reasons. First is about practicality; each module weighs over 120 lbs (54 kg), so if it was just one module it would be very heavy (close to 400 lbs (181 kg)) and tough to move. With it being comprised of three modules, each is more manageable to move.

Another reason has to do with the electrical wiring typically found inside homes. If the MC2.1KW was just one module, it would need to plug into a high voltage outlet (for example: the kind of outlet used by electric ranges in the United States). With it divided up into three modules, each can have a more common plug that works with the type of outlets commonly found in homes so that special wiring does not need to be installed inside your walls.

FULL POWER WITH NO SACRIFICES

A SONIC LEAP FORWARD

Our patented Solid Cinch^™ speaker binding posts easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the posts are gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables. There are dedicated binding posts for 2, 4 and 8 Ohm impedances, with the connectors for each impedance rating located on a separate output platform on the back of the Output Module. Each output platform also has three sets of identical binding posts to facilitate bi- or tri-wiring your loudspeaker.

Four of our McIntosh Monogrammed Heatsinks^™ are found on each Power Module. Made from high quality materials with excellent thermal conductivity properties and connected to advanced high current output transistors that eliminate thermal equilibrium lag time, these heatsinks maintain efficient heat dissipation, ensuring consistent audio quality from the first note to the last.
