Take control of your studio monitoring setup with the Mackie Big Knob Passive Studio Monitor Controller, a compact desktop solution designed for professional and home studios alike. This 2x2 monitor controller lets you easily switch between two input sources and two pairs of studio monitors with crystal-clear, uncoloured sound quality thanks to its passive circuitry design.
Favoured by engineers, producers and content creators worldwide, the Big Knob Passive provides intuitive hands-on control for quick source selection, precise volume adjustment, and fast access to essential functions like mute, mono and dim. Whether you’re producing music, mixing a podcast or editing video content, the Big Knob Passive ensures consistent, accurate monitoring performance in every session.
Designed to make your studio workflow smoother, the Big Knob Passive keeps everything you need right at your fingertips. Its large central volume knob gives you fine control over output levels, while dedicated source and monitor select switches let you instantly compare playback between devices or speakers. The inclusion of mono, mute and dim buttons allows for rapid referencing and critical listening adjustments during mixing and mastering.
Unlike active controllers, the Big Knob Passive features a purely passive signal path, ensuring maximum transparency and zero added noise or coloration. This design makes it the ideal choice for critical listening environments where accuracy is key. The result is a clear, natural sound that faithfully represents your mix, helping you make better production decisions faster.
Mackie’s renowned “Built-Like-A-Tank” construction ensures the Big Knob Passive can withstand the demands of daily studio use. Its robust metal housing and high-quality components make it a dependable addition to any setup, from bedroom studios to professional recording facilities.
Every Big Knob Passive includes Waveform OEM™ DAW—a powerful, unrestricted digital audio workstation—and the DAW Essentials Collection™, featuring 16 professional-grade effects plug-ins such as EQ, compressor, reverb, delay, and limiter.
