The feature-packed McIntosh MI254 4-Channel Digital Power Amplifier is worth checking out! 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 functionally 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 need noisy cooling fans to maintain nominal operating temperature. Alongside the 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.

Benefits of McIntosh MI254 4-Channel Digital Power Amplifier:

Perfect for home theater surround sound speakers

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: Power 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.

Illuminated McIntosh logo

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.
