$4,000.00
The versatile MI128 8-Channel Digital Amplifier can be used in many applications, ranging from distributed audio to home theater to stereo listening.

 

 

OVERVIEW

The MI128 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.

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.

FEATURES

 

  • Loudspeaker Guard signal overload technology that prevents overdriving the speakers
  • 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
  • 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.
