McIntosh has announced the MC611 Quad Balanced Power Amplifier. The monoblock MC611 Quad Balanced Power Amplifier produces 600 Watts of power. A pair of MC611s can drive a hifi, or add additional units to power each speaker of a home theatre.

Utilising McIntosh’s output Autoformer™ technology, the full 600 Watts will be delivered to the speaker regardless if it has 2, 4 or 8 Ohm impedance. The MC611 has received numerous updates and improvements compared to the previous MC601 model. Chief among them is that filter capacity has been doubled which has resulted in a 55% increase in dynamic headroom from 1.8dB to 2.8dB.

The front panel features new direct LED backlighting for improved appearance and colour accuracy. On top, the audio Autoformer and power transformer are now contained in new glass topped enclosures. Behind them are 2 McIntosh Monogrammed Heatsinks™ which connect to high current output transistors. On the back, there continues to be 3 sets of our Solid Cinch™ speaker binding posts (1 set for each speaker impedance), but space has been added between each set to allow for easier speaker cable connectivity. Other enhancements include heavier gauge internal wiring, upgraded circuit components and the addition of an eco-friendly power management system. In addition to all these improvements, the MC611 remains full of other McIntosh technologies including Power Guard®, Sentry Monitor™, a Quad Balanced design and Power Control. Both a balanced and unbalanced output are included to make bi-amping or tri-amping speakers easier; they can also be used to send the audio signal to a secondary system or to connect a powered subwoofer.

The MC611 sits on a polished stainless steel chassis and features the 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.
