Typical Big Knob Passive Setup
Big Knob Passive is the perfect monitoring tool as a level control for a home / project studio
or integrated as part of a larger studio. There are many great things about the Big Knob Passive,
but one of the features is no need for power...it can be placed anywhere to your heart’s content!
After you’ve decided on a spot, it’s time to make connections.
In this example, a computer installed with your favorite DAW is connected to the Source Input A
L/R jacks. The Source Input B jacks may accept 1/4" inputs and an 1/8" stereo input. If both inputs are
connected simultaneously, the 1/8" stereo line input will take priority over the 1/4" connection. In this
case, we hooked up a smartphone to the 1/8" stereo line input jack.
The output section is as straightforward as the input section. Here we connected a pair
of XR Series studio monitors to the Mon Output A L/R jacks and a pair of MRmk3 Series studio
monitors to the Mon Output B L/R jacks.
Now that connections have been made, the fun begins! The top panel has a variety of switches,
buttons and something else...what was it? Oh yeah, a BIG knob, dead center! These allow you to select
between the inputs, outputs, control levels and more. Descriptions of the Big Knob Passive features starts
