Description
The McIntosh MI128 is a powerful and flexible 8‑channel digital amplifier and audio processor, purpose‑engineered for high‑performance custom installation and multi‑room audio systems.
Blending McIntosh’s renowned sonic integrity with advanced digital control, the MI128 serves as a sophisticated backbone for whole‑home or dedicated audio applications where reliability, scalability, and sound quality are paramount.
On the front panel, multi-color LED indicators display the status of each channel. On the back are unbalanced inputs for each channel plus 2-pole Phoenix style push-in speaker terminals. Also located on the back are volume controls for volume balancing, along with 2 digital audio inputs (either coax or optical) that can be bussed, and channel summing circuits for easy mono signal distribution.
Other features included on the MI128 are: Loudspeaker 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 MI128 includes many McIntosh design cues including a black glass front panel housing an illuminated McIntosh logo, along with a familiar form factor that is highlighted with silver trim.
