MI128 Power Amplifier

$4,500

The McIntosh MI128 is an eight-channel digital power amplifier designed for distributed audio and custom installations. It provides 120 watts per channel into 8 ohms or 150 watts per channel into 4 ohms from a rack-mountable 2U chassis.

Bussable unbalanced inputs can simplify signal distribution across several channels, while on/off signal sensing and Power Control support automated operation. Power Guard and Sentry Monitor supervise each channel, making the MI128 a compact way to supply multiple rooms or loudspeaker zones from one amplifier.
