McIntosh MC 1.25 KW 75th Anniversary AC

• 75th Anniversary Edition
• 1,200 Watt Quad Balanced Monoblock
• Redesigned from top to bottom

The MC1.25KW Quad Balanced Power Amplifier is one of the most advanced amplifiers by McIntosh. Redesigned from top to bottom, it replaces the venerable MC1.2KW as McIntosh's most powerful single chassis monoblock amplifier. A simple glance at this 158 pound (71.7 kg) amp is enough to convey its power and performance capabilities, but when you hear it – then you’ll truly understand what it can do.

The MC1.25KW outputs 1,200 Watts of pure power into a single channel with a nearly imperceptible total harmonic distortion of 0.005%. This astonishing amount of power is fully available to 2, 4 or 8 Ohm speakers via the Autoformer™ technology. A pair of these amps can anchor a home audio system that can rival nearly any stereo system in the world.

The MC1.25KW is a fantastic amplifier with "unlimited dynamics, crushing power, accuracy, speed, authority, precise control, purity and transparency." Recipient of Reference Award. - Hi-Fi Voice

Updates and enhancements abound in the MC1.25KW. A 50% increase in filter capacity improves the performance of low end frequencies as well as increasing dynamic headroom. The top of the amp showcases an updated yet unmistakable McIntosh industrial design that will fit right in with current McIntosh products or those made decades ago. The audio Autoformer and power transformer remain located just behind the front panel but are now contained in new glass topped enclosures. In between them is new circular glasswork housing the amplifier’s name badge that is adorned with a decorative trim ring.

1949 – 2024: MCINTOSH CELEBRATES 75 YEARS OF AUDIO EXCELLENCE
Since McIntosh's inception in 1949 under the visionary guidance of Frank McIntosh, the company has relentlessly pursued the art of sound reproduction. The year 2024 marks a historic milestone for McIntosh as it proudly celebrates its 75th anniversary - a testament to its enduring passion for creating audio experiences that exceed expectations.

THE MC1.25KW 75TH ANNIVERSARY EDITION
In honor of this momentous occasion, McIntosh presents the special MC1.25KW 75th Anniversary Edition. The Anniversary Edition boasts a distinctive dual anodized laser-engraved badge proudly displaying the 75th Anniversary logo on the top, while each handle is engraved with a graceful "75 years" inscription. This exclusive edition is a celebration of McIntosh's relentless pursuit of excellence. All performance specifications, functionality, and dimensions of the anniversary edition are the same as the non-anniversary version.

HOW TO SECURE YOUR PIECE OF THIS SONIC LEGACY
When placing your order with your dealer in 2024, you must specify you want the MC1.25KW 75th Anniversary Edition. Otherwise you will receive the stock version that does not include the commemorative anniversary markings.

COMPLETE 75TH ANNIVERSARY PRODUCT FAMILY
The 75th Anniversary product lineup extends beyond the MC1.25KW, encompassing the MC2.1KW Monoblock Amplifier, C12000 Solid State and Vacuum Tube Preamplifier, MA12000 Integrated Amplifier, and MCD12000 SACD/CD Player. These anniversary editions of these audio marvels stand as beacons of artistry and precision, embodying the very essence of McIntosh's 75-year sonic odyssey.

With each, McIntosh invites you to share their passion for the profound impact of music, craftsmanship and the transformative experience of listening. Let the MC1.25KW and its companions elevate your auditory senses, inspiring you to explore new realms of sonic bliss.

The rear of the unit features 4 of the McIntosh Monogrammed Heatsinks™. Made from high quality materials with excellent thermal conductivity properties, these heatsinks are so efficient at dissipating heat that they warrant bearing the McIntosh “Mc” logo. They connect to advanced high current output transistors that eliminate thermal equilibrium lag time so that the first musical note played sounds just as good as songs played later in your listening session.

The heatsinks are capped with handsome ventilation trim plates. These trim plates and the circular trim ring are made from aluminum and are finished to match the front panel handles.

The AC receptacle has been repositioned to provide additional clearance so a wider assortment of power cords can more easily be used. All of this sits atop a polished stainless steel chassis which rests on 4 new redesigned feet that feature a chamfered edge. Other updates include an updated power transformer, heavier gauge internal wiring, upgraded circuit components, and the addition of the power management system that will turn the amp off after a set amount of time when no input signal has been detected.

With all the changes and improvements made in the MC1.25KW, one thing that hasn’t changed is the large, fast responding 11” (27.9 cm) blue Watt meter that accurately shows the amp’s power output. Also unchanged is the signature black glass front panel with control knobs, illuminated logo, and aluminum end caps with handles. The front panel and meter have new direct LED backlighting for improved appearance and color accuracy.

Other exclusive McIntosh features included in the MC1.25KW include:

• Power Guard® that monitors and adjusts the output signal at the speed of light and makes real time adjustments to prevent harsh sounding and potentially speaker damaging clipping
• Sentry Monitor™ - the fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal
• Quad Balanced design that cancels virtually all noise and distortion that may have crept into the audio signal
• Power Control to send power on/off signals to other connected McIntosh components (such as CD Players, turntables, tuners and media streamers) for easy system power up and shutdown
• The patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables

Both a balanced and unbalanced output are included to make bi-amping or tri-amping your speakers easier; they can also be used to send the audio signal to a secondary system if your preamplifier does not have enough outputs or to connect a powered subwoofer.
