Mackie Big Knob Passive Studio Monitor Controller

The Big Knob Passive is a purely passive monitor controller for the desktop, built for engineers who want to switch between two sources and two monitor pairs without adding any active electronics to the signal path. With no power required and no circuitry to color the audio, what comes in is what reaches the speakers.

A large, smooth volume knob sets the level, and simple source and monitor selection makes A/B comparisons quick. It is the straightforward, affordable way to add proper monitor control to a small studio or an editing suite.
