Ideal for completing both distributed sound and Hi-Fi and Home Theater systems, the MI254 is a four-channel power amplifier equipped with highly efficient and sophisticated closed-loop digital switching technology, complemented by robust power supplies. power supply to guarantee very high level performance.
Designed for rack mounting, the MI254 includes McIntosh 's iconic blue-background analog level indicators that show the sum of the powers delivered by channels 1 and 2 on one side and 3 and 4 on the other, as well as LED indicators They report on the operational status of each channel.
Another relevant feature of the MI254 is the new Loudspeaker Guard overload protection technology from McIntosh , to which is added the now classic Sentry Monitor from the American firm, which deactivates the output stage before the current exceeds the limits of safe operation.
As a power amplifier for custom installations, the MI254 includes several external control options, such as a sensor for automatic activation/deactivation.
