Hi, I've recently bought a pair of KRK Rokit RP8 G2 studio monitors to use for casual listening, production and djing. It's the latter use that is causing me problems. I'm getting noise in the recording signal every time I connect the KRK to the mixer (Numark DXM09). I've tried to pluging the mixer and/or the speakers to an UPS, changing between RCA and TRS - XLR cables and connecting the monitors to different output channels from the mixer (Master, Record, Both), but the noise is always present. I've no problem with the recording signal when I connect the master output of the mixer to an old stereo system instead of the KRK monitors though. I've tried many possible configurations but I had no luck. Do you know how can I identify and fix this problem? Thanks in advance, André.
