The versatile MI128 8-Channel Digital Amplifier can be used in many applications ranging from distributed audio to home theater to stereo listening. It 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.
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.
