therein lies your problem š
In all seriousness though, try and find a proving unit first. Start at one end and work backwards. Sounds like youāve got a few options to work with, so start with the speakers. Try them on a different mixer and CDJ/Controller setup. Prove the speakers are fine first. Then work backwards from there, testing a different mixer is fine with the speakers before then plugging in your rotary again. Use your CDJ/controller for the test if you know thatās fine, before putting your vinyl decks back on last. Bit of a ball ache, but itāll help isolate the problem.
