The McIntosh founding fathers created a solid foundation based on sound business and scientific principles that continue to guide the company.
The people behind the scenes at McIntosh possess a desire to achieve the finest quality standards. McIntosh has defined quality sound reproduction and sets the standards for performance, reliability and service. McIntosh has handcrafted prestige audio products in Binghamton, NY since 1949. Glassfront panels, Output Autoformers®, Blue Watt Meters and Power Guard® are some of the innovations that enhance their product longevity.
Handcrafted in America since 1949, McIntosh is known for offering distinguished quality audio products, superior customer service and the ultimate experience in music and film. McIntosh continues to define the ultimate home entertainment experience for discriminating consumers around the world, with the iconic "McIntosh Blue" Watt Meters globally recognised as a symbol of quality audio. Since its inception, McIntosh has been powering some of the most important moments in music history and pop culture. From President Lyndon Johnson’s inauguration speech to Woodstock to the infamous Grateful Dead “Wall of Sound,” McIntosh has not only witnessed history, it has shaped it. In 1969 McIntosh Amplifiers powered Woodstock, a pivotal moment in Music history. Three days of peace, love and music for the hundreds of thousands who attended.
Over the years, many famous musicians, recording artists and producers have selected McIntosh audio systems for the rich quality of sound, to experience music the way the artist intended. The loyalty from the music community began in the 1960s era of rock and roll. Several of their brand ambassadors have shared their experience and passion for McIntosh which has often spanned across decades.
The MI254 4-Channel Digital Amplifier is a versatile multi-channel amplifier ideal for use in distributed audio, home theater or 2-channel stereo playback. It delivers 250 Watts into 8 Ohm speakers or 300 Watts into 4 Ohm speakers via its highly sophisticated closed loop digital switching amplifiers. These amplifiers are paired with extremely robust power supplies that produce performance levels rarely achieved in distributed audio.
It has installer-friendly physical dimensions and is 2U rack mountable via the included mounting ears (the mounting ears are removable for non-rack installations). As a highly efficient Class D amplifier, it does not require noisy cooling fans to maintain nominal operating temperature. In addition to distributed audio use, the MI254 is well suited for home theaters to drive surround sound speakers and could be integrated into virtually any existing home theater system.
On the front panel are two blue McIntosh Watt Meters that display the summed power output of channels 1 + 2 and channels 3 + 4. Multi-color LED indicators display the status of each channel. The back panel includes both a balanced and unbalanced input for each channel along with our standard 5-way speaker binding posts.
Other features that come with the MI254 are: Loudspeaker Guard signal overload technology that prevents overdriving the speakers; our Sentry Monitor™ 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; BUS input & outputs to easily distribute a stereo signal to multiple outputs and/or multiple amplifiers; individual channel inputs; 12 Volt triggering capabilities; and eco-friendly on/off signal sensing that turns the unit off if no input signal has been detected for a set amount of time or automatically turns the amp on when it senses a signal.
The MI254 includes many McIntosh design cues including a black glass front panel, blue Watt meters, an illuminated McIntosh logo, and a familiar form factor highlighted by silver trim. Contact your local dealer to learn more about integrating the MI254 into your custom audio installation.
