Sadly, wanted to use this for an output from the desk to the input on my BOSE L1s.
However, it won't work.. I've since discovered I need to "sum" the desk outputs, they don't mix to a stereo 1/4" jack.
If you try, it phases.. lots!!
You need a summing box, palmer PAN 05, or ART Splitcom Pro.
I'll find some use for the lead, its well made, and always good to have a selection of random leads that are always needed... (most of the time by the guitarist!)
