Studio Command System
The Mackie Big Knob Studio Command System is a simple yet powerful desktop audio control center. It lets musicians and engineers get right to the business of making music in four major ways: level control, studio monitor selection, input source selection, and talkback and headphone control.

Passive Monitor Controller
Mackie Big Knob Passive is a proven design that delivers professional level control, plus source and monitor selection for studios of any size. It’s like having an audio traffic cop in your studio. Your best mix is always one that is achieved through disparate monitoring comparisons. Big Knob Passive makes that easier than ever.

Studio Monitor Controller
Mackie Big Knob Studio combines premium 96khz/24-bit recording with the proven performance of the world’s bestselling monitor controller. Capture world-class recordings via dual Onyx™ preamps and professional studio features like zero-latency overdubbing and built-in talkback for artist communication. Easily select from three sources, including USB playback from your DAW and switch between two pairs of studio monitors.
