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 switchingThe 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. |  |
MC3 Applications
 Using the MC3 with 2 sets of monitorsThe most common application is switching between two sets of monitors. This enables the engineer to hear how the mix will translate at various levels using different sized drivers. The mono switch is used to check AM radio compatibility. |  Adding a sub to the playbackWith more and more home theaters using subs, it is important to audition mixes with and without the added bass. The MC3 lets you switch in a sub as needed. Top mount dials let you adjust the level going to the sub for optimal mix. |  Using the MC3 as a routerThe MC3 can be used as a basic audio router for applications such as sending a stereo signal to two rooms. Applications include splitting the signal between the living room and kitchen or two zones in a restaurant. |
