This is a 3×2 Matrix Mixer. With three mono inputs and two mono outputs there are many routing options. Each input has a two volume controls, one for each output. This could be used to create stereo mixes from mono sources or run the outputs through two different signal chains or amplifiers. You can also send one output through effects and then back in on itself to create a feedback loop.
The circuit is completely passive and requires no power, as with all passive matrix mixers there is some gain loss and crosstalk. It is housed in a rugged raw aluminum die cast case.
This will also work in reverse as a two in three out splitter. The knobs can be pulled off and reorientated depending on what works best for your setup. Handmade in Oakland, CA USA.
Shipping to the US is a flat $10, everywhere else is $22 for the first item and $8 for each additional item.
I am away right now. All orders will ship on April 28th. My apologies for the wait.
