After becoming a tad miffed at how the PO’s work when chained and the associated volume issues, I started to think about a solution to mixing them and syncing them whilst still retaining the casual portability that makes them so much fun, I was using 2 of my 6 channel passive stereo mixers with great results, so I decided to expand upon the idea and come up with a solution specifically for this and other common studio/modular issues, such as clock distribution, mult-ing signals, and passive mixing.
I decided that 4 inputs would be a good compromise, not too much signal loss, nice and small and affordable, then I decided that it would be super handy to have it switchable between mono or stereo, so that it could be used for clock or modular signals that require TS connectors, or TRS for stereo audio such as iOS, OP1 etc. and that it should be bi-directional so it can be used as 4-1 or 1-4. The idea being that it would be a flexible little tool for common needs in a studio or live environment.
So here it is, the 4 way passive mixer/distributor, yours for £20GBP plus shipping, or 2 for £35GBP
The idea of having 2 is one to handle PO sync, another for PO audio
