Built with McIntosh’s precision engineering, the MI128 delivers 120 watts per channel into 8-ohm speakers or 150 watts per channel into 4-ohm speakers, powered by advanced closed-loop digital switching amplifiers paired with extremely robust power supplies. This combination ensures clean, efficient performance with the kind of reliability and output quality rarely found in distributed audio applications.\u003c\/p\u003e\n\u003cp\u003eEngineered for professional installations, the MI128 features installer-friendly dimensions and comes 2U rack mountable using the included mounting ears, which can also be removed for non-rack setups. As a highly efficient Class D amplifier, it maintains optimal operating temperatures without the need for noisy cooling fans ensuring completely silent operation and maximum reliability in any environment.\u003c\/p\u003e\n\u003cp\u003eThe front panel includes multi-color LED indicators that clearly display the status of each channel for quick system monitoring. On the rear panel, you’ll find unbalanced inputs for each channel along with 2-pole Phoenix-style push-in speaker terminals for secure and easy connections. Additional rear-panel features include individual volume controls for precise level balancing, two digital audio inputs (coaxial or optical) that can be bussed, and channel summing circuits that allow effortless distribution of mono signals.\u003c\/p\u003e\n\u003cp\u003eThe MI128 is equipped with essential McIntosh protection and performance technologies. Power Guard® prevents speaker damage by monitoring and adjusting overdriven signals before clipping occurs, while Sentry Monitor™ safeguards the amplifier by shutting down the output stage during unsafe current levels and automatically restoring operation once conditions normalize. Designed for seamless integration, the MI128 offers BUS inputs and outputs for efficiently distributing stereo signals across multiple channels or amplifiers, individual channel inputs, 12-volt triggering, and eco-friendly signal sensing that automatically powers the amplifier on or off depending on input activity.\u003c\/p\u003e\n\u003cp\u003eVisually, the MI128 stays true to McIntosh tradition with its black glass front panel, illuminated McIntosh logo, and signature silver trim that gives the amplifier a refined and timeless presence in any custom installation. Whether used in whole-home distributed audio, advanced home theater systems, or high-performance stereo zones, the MI128 delivers the exceptional audio quality and enduring craftsmanship expected from McIntosh.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications \u003c\/h3\u003e\n\u003ctable style=\"width: 100.087%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 37.3412%;
