So I have two prosound DMGs with two copies of LSDJ linked together master/slave. My PA has two inputs, so I plug both the DMGs in. However I can only hear the first one. I played with the volume on the PA, but got nothing out of gameboy2. They both say they are playing. But it gets weird because when i unplug the jack from gameboy1 then suddenly gameboy2 is able to play. And as soon as I plug gameboy1 back in I can't hear gameboy2. This same problem persisted when I tried it on my mixer. and when I used a y-cable to combine them. But the same setup works if I replace the 2nd DMG with my color...
What the hell?
