Mackie Bigknob Studio +

The Legendary Big Knob, Now at the Heart of Your Studio

With the "Big Knob Studio+", Mackie evolves its iconic controller into a hybrid solution: both a control center and a high-performance USB interface. Compared to earlier generations, this "Studio+" version adds 24-bit / 192 kHz conversion, Onyx preamps, and expanded routing, naturally positioning it as the flagship of the Big Knob range in modern studios.

Who Is It For and What Are Its Uses?

Designed for producers, sound engineers, content creators, and schools, the Big Knob Studio+ simplifies switching between multiple speaker pairs, sources, and headphones. In control rooms, advanced home studios, or vocal booths, it centralizes monitoring, talkback, and recording without multiplying devices or patching.
