    “…into an old Pioneer DJM400.”

    I suspect the mixer is your problem. It may require servicing, or at least a good cleaning. Would also be a good idea to check the cables just to make sure it isn’t one of them with the issue.

    Are they all sharing the same power point? You want everything coming from the same circuit ideally, or more specifically, earthed via the same means. Different circuits will likely mean a small difference in earth loop impedance which can give small differences in working voltage and cause interference. My speakers/amps share the same plug socket as the mixers.

    Old DJM 400 – there is your problem right there

    The DJM400 had most of its connections not really well isolated and the print of the boards were also pretty open and close to other circuits. Hence it is prone to get crackling during usage especially from faders and knobs.
    Some of it can sometimes be mitigated by WD40 spray and patient disassembly and cleaning, but the time comes where faders and knob connectors are just too corroded to be any good. To replace those however is most of the time more expensive than the used mixer itself, hence why they are going so cheap.
