Description

The versatile MI128 8-Channel Digital Amplifier can be used in many applications ranging from distributed audio to home theater to stereo listening. It delivers 120 Watts into 8 Ohm speakers or 150 Watts into 4 Ohm speakers via highly sophisticated closed-loop digital switching amplifiers that are paired with extremely robust power supplies to produce performance levels that are rarely achieved in distributed audio.

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.

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 Monitorâ„¢ 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.
