■

The MI1250 12-Channel Digital Amplier can distribute pristine music

playback in multiple rooms in your home.

■

Delivers 50 Watts into 8 Ohm speakers or 90 Watts into 4 Ohm speakers

via highly sophisticated closed loop digital switching ampliers 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 (ears are removable for non-rack installations).

■

A highly efcient Class D amplier, 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 ampliers; individual channel inputs;

12 Volt triggering capabilities; and eco-friendly on/off signal sensing.
