Radial MC3

Passive Studio Monitor Controller


About this item



The Radial 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.

  • Select between two sets of powered monitors in the studio
  • Passive straight-wire audio path for transparent audio
  • Convenient subwoofer control, Mono & Dim switches
  • Built-in headphone amplifier for silent monitoring

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 speakers 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.
