The passive audio path ensures pristine sonic integrity is maintained throughout your signal chain. More than just a level control solution, Big Knob Passive features the ability to choose between two sources and two monitor pairs.

Ideal for simple level control at a home or project studio or for integration in a large studio or group of editing suites, Big Knob Passive is the “Built-Like-A-Tank,” affordable monitoring control solution.

The Mackie Big Knob has proven itself for more than a decade as the go-to monitor controlling solution for project and professional studios. The all-new Big Knob family takes the best of this classic workflow, delivering the right solution for the modern studio.

More than just a level control solution, Big Knob Passive features the ability to choose between two sources and two monitor pairs, creating an affordable “Built-Like-A-Tank” monitor control solution.

Professional mono, mute and dim functions offer expanded control over your sound. Switch to Mono to ensure your mix sounds like it should from any system. Mute and Dim provide an instant kill switch or significant attenuation to the output without changing your main level setting.

Big Knob Studio uses a completely passive audio path. This means that audio integrity is preserved throughout. This also means that no power supply is needed. Just plug in your sources and monitors and you're good to go.
