Product Details
■ Product Description
Introducing the Big Knob Passive by MACKIE, a standard monitor controller for home recording and studio environments.
Featuring a passive design without active circuitry, it offers an extremely pure monitoring experience with no coloration of sound.
It includes switching for two input sources and two speaker outputs, along with a large volume knob for quick, on-hand operation, and MONO, MUTE, and DIM switches. This dramatically improves workflow efficiency.
This is a one-owner unit purchased new from Rock oN in 2019.
