McIntosh Labs Release New Monoblock Amplifier MC611
NEWS: McIntosh announces new tech-rich 
600-watt mono-block power amplifier the MC611

Proprietary Autoformer™ technology ensures all 600 watts can be delivered to the loudspeaker


Binghamton, NY, USA, February 7th, 2018: McIntosh, the global leader in prestigious home entertainment and ultimate-quality audio for over 65 years, has introduced the new MC611 Quad Balanced Power Amplifier (£19,995 per pair).

McIntosh has launched the new MC611 Quad Balanced Power Amplifier. The new high-power monoblock amp offers a number of key updates and improvements over its predecessor, the MC601. Primary among them is a doubling of filter capacity resulting in a dramatic 55% increase in dynamic headroom (from 1.8dB to 2.8dB) helping to improve the bass frequency performance.
Proprietary Autoformer™ technology

The MC611 Quad Balanced Power Amplifier produces 600 watts of power – enough to drive virtually any loudspeaker. McIntosh’s unique Autoformer™ output technology ensures that the full 600 watts are delivered to the speaker, regardless of impedance, allowing the MC611 to be truly used to its full potential.

Design improvements

There have also been a number of design upgrades. The front panel features new direct LED backlighting for improved appearance and colour accuracy. In addition, on top of the unit, the audio Autoformer and power transformer are now contained in new glass-topped enclosures. The amplifier also features two McIntosh Monogrammed Heatsinks™ which connect to advanced high-current output transistors that help eliminate thermal equilibrium lag-time.

The back panel offers three sets of McIntosh Solid Cinch™ speaker binding posts (one set for each speaker impedance) and additional space has been added between each set to allow for easier speaker cable connectivity. Further enhancements include heavier gauge internal wiring, upgraded circuit components and the addition of McIntosh’s eco-friendly power management system.

Further McIntosh technologies

In addition to the improvements over its predecessor, the MC611 also features a range of further exclusive McIntosh technologies including: Power Guard®, Sentry Monitor™, a Quad Balanced design and Power Control. Both balanced and unbalanced outputs are included to facilitate bi-amping or tri-amping loudspeakers; these can also be used to send the audio signal to a secondary system or to connect a powered subwoofer.

The MC611 sits on a beautiful polished stainless steel chassis and features the timeless McIntosh aesthetic of a black glass front panel, illuminated logo, control knobs, aluminium handles and a large 8” (20.3 cm) fast-responding blue watt-meter.
