Product Information

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.

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
