The Mackie Big Knob Studio+ Controller seamlessly integrates into any studio environment thanks to its various I/O options and provides you with everything you need for monitoring and signal routing in a modern studio, including two headphone outputs, a dedicated studio out, and a true cue mix. For over a decade, musicians and audio engineers have relied on the products of the Mackie Big Knob Series for studio monitor control. This will not change in the near future, as the next generation of the Big Knob Series, featuring the Big Knob Passive, Big Knob Studio, and Big Knob Studio+, builds on the solid workflow of the previous generation while introducing new features, such as USB interfacing with two Onyx Dual Mic Preamps (available only in Studio and Studio+).
