MI254 4-Channel Power Amplifier
Ideal for Home Theater Systems & Distributed Audio Systems

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.
