McIntosh MI254 Digital Power Amplifier
8290,00 €
The MI254 4-channel digital power 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.
Overview
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: 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.
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.

Build a Reference Stereo System with McIntosh
McIntosh is most often chosen as the heart of a serious two-channel system. Start with an integrated amplifier for a clean, powerful foundation, or step up to separates (preamplifier + power amplifier) for maximum scale and control. Then complete the chain with sources that match how you listen — streaming and digital playback, or a vinyl front end with a proper phono stage. We’ll help you keep the system coherent in a real room and choose a path that makes long-term sense.
Explore compatible categories to build a balanced McIntosh-based system:
– Integrated Amplifiers
– Preamplifiers
– Power Amplifiers
– Network Players / Streamers
