Passive Studio Monitor Controller
The MC3™ monitor controller is a studio tool that enables you to take command of your monitor system, with the ability to quickly select between two sets of powered speakers and adjust signal levels, and additional control for headphones and a subwoofer.

Compact monitor switching
The MC3 handles all of your studio monitor switching needs in a small footprint that easily fits on any desktop. Connect two sets of powered speaker and a subwoofer and easily select any combination, with a large master volume control for setting levels. A Dim switch lets you temporarily lower the speaker level without altering your main volume setting, and a Mono switch provides an easy way to check for phase compatibility. The MC3 features a passive audio circuit for clean and transparent audio, along with an active headphone amp to drive multiple sets of headphones and monitor silently when necessary.
