McIntosh MI254 Details

McIntosh MI254: 4-Channel Digital Amplifier

  • 250 Watts into 8 Ohms
  • 300 Watts into 4 Ohms
  • 4-Channel distributed audio amplifier
  • Also great to drive home theater surround sound speakers

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 the standard McIntosh 5-way speaker binding posts.

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.
