Mackie BIG KNOB STUDIO PLUS 4x3 Studio Monitor Controller

The Mackie Big Knob Studio+ is a 4x3 studio monitor controller and USB audio interface designed to serve as the central command hub for project and professional studios alike. Its core purpose is to simplify the process of managing multiple audio sources and monitor outputs — a task that can otherwise require a tangle of patch cables and manual re-routing. With four selectable stereo inputs, you can keep your DAW, a secondary playback device, and other sources connected simultaneously, switching between them with dedicated buttons. On the output side, three selectable stereo outputs let you instantly compare your mix on different monitor pairs, from nearfields to larger reference speakers.

Beyond monitoring, the Big Knob Studio+ pulls double duty as a recording interface. Its two built-in Onyx mic preamps — the same preamp design found in Mackie's higher-end mixing consoles — provide clean gain for microphones and instruments, with recording resolution up to 192kHz/24-bit. Dual headphone outputs with independent level controls make it practical for tracking sessions where both the engineer and talent need separate headphone mixes. The signature oversized volume knob at the center of the unit provides smooth, precise level adjustment, giving you confident control over your monitoring environment without needing to reach for a mouse.
