McIntosh MI1250 12-Channel Digital Power Amplifier

MI1250

12-Channel Digital Distributed Audio Amplifier

Delivers pristine music playback to multiple rooms for whole house audio.

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.

• The MI1250 12-Channel Digital Amplifier 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 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 (ears are removable for non-rack installations).
• A highly efficient Class D amplifier, it does not require noisy cooling fans to maintain nominal operating temperature.
• Multi-colour 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.
• Dimensions: 17-1/2" (44.45cm) (19" (48.3cm with mounting ears)) x 4-5/16" (11cm) (including feet) x 21" (53.3cm) (including front panel and cables)
• Weight: 22 lbs (10 kg)

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 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

The MI1250 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. Contact us to learn more about integrating the MI1250 into your custom whole house audio installation.
