BRAND: McIntosh
SERIES: MI128
TYPE: Power Amplifier
OVERVIEW
- The versatile MI128 8-Channel Digital Amplifier can be used in many applications ranging from distributed audio to home theater to stereo.
- 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.
- Installer-friendly physical dimensions and is 2U rack mountable via the included mounting ears (the 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.
- Multi-color LED indicators display the status of each channel. Features unbalanced inputs plus 2-pole Phoenix style push-in speaker terminals for each channel.
- Includes 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: Loudspeaker Guard signal overload technology that prevents overdriving the speakers; Sentry Monitor™ short-circuit protection that disengages the output stage before current exceeds safe operating levels; 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.
