■ 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: Power 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.
