McIntosh MC2.1KW Monoblock Power Amplifier

McIntosh MC2.1KW Reference Monoblock Power Amplifier

2,000 Watts. Three Chassis. One Loudspeaker.

The McIntosh MC2.1KW Monoblock Power Amplifier sits at the absolute top of McIntosh solid-state amplification. Delivering an extraordinary 2,000 watts to a single loudspeaker, it is designed for reference systems where power reserves, control, and scale are pushed to their logical extreme.

And the MC2.1KW isn't simply an oversized conventional monoblock. Each amplifier is actually a three-chassis system consisting of one Output Module and two separate 1,000-watt Power Modules.

For a stereo system, a pair of MC2.1KWs means six chassis and 4,000 watts of total rated amplification dedicated to two loudspeakers.

This is McIntosh amplification without compromise.

Two 1,000-Watt Amplifiers Working as One

The architecture behind the MC2.1KW is as impressive as its output specification.

The incoming signal first enters the Output Module from the preamplifier. From there, an in-phase signal is sent to one 1,000-watt Power Module while an out-of-phase signal is sent to the second.

After amplification, both signals return to the Output Module and drive opposite ends of a bifilar-wound McIntosh Autoformer.

The two signals are recombined, their power is summed, and unwanted noise is reduced or canceled.

The result is 2,000 watts of McIntosh power available to the connected loudspeaker.

Full Power Into 2, 4 or 8 Ohms

As with McIntosh's other Autoformer-equipped reference amplifiers, the MC2.1KW isn't limited to producing maximum power into a single speaker impedance.

The full 2,000 watts is available into 2, 4, or 8 Ohms.

Dedicated speaker terminals are provided for each impedance, with each located on its own output platform on the rear of the Output Module.

McIntosh goes even further by providing three identical sets of Solid Cinch binding posts for each impedance, making it significantly easier to bi-wire or tri-wire compatible reference loudspeakers.

For an amplifier intended to remain at the center of a system for years, the ability to deliver full rated output across such a broad range of loudspeakers provides enormous flexibility.

Why Three Chassis?

At this level, dividing the amplifier into three components isn't just an engineering statement. It's practical.

Each MC2.1KW module weighs more than 120 pounds. Combining everything into a single enclosure would result in an amplifier approaching 400 pounds, making installation extremely difficult.
