The versatile MI1250 12-Channel Digital Amplifier can distribute pristine music playback to multiple rooms in your home.

It delivers 50 Watts into 8 Ohm speakers or 90 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.

• Ideal for multi-zone distributed audio
• 50 Watts into 8 Ohms
• 90 Watts into 4 Ohms
• 2U rack mountable
• Channel summing circuits for mono signal distribution
• Volume controls for each channel
• Bussable inputs
• Signal sensing
• Power Guard and Sentry Monitor

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 back are unbalanced inputs plus 2-pole Phoenix style push-in speaker terminals for each channel. 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 MI1250 are:

• Power Guard signal overload technology that prevents overdriving the speakers.
• Our 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 to automatically turn other connected McIntosh components on and off.
• 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.
