Faint buzz/white noise is a Funktion One Install
One of our clients has an issue with a faint crackle/buzz/white noise coming through her speakers. It is barely noticeable but it is there.
We tried the gambit of swapping cables, power sources, mixers etc
The only thing that worked was from DJ mixer plugged straight into processor from upstairs with 100’ xlrs seemed to squash the buzz.
But when I brought that mixer downstairs and used the short XLRs it came back. Which is why i thought it was the cables.
Signal Flow: Pioneer DJM-900nxs2 -> stereo 100’ xlr -> Yamaha 6ch Mgxu6 -> stereo 6’ xlr -> xta processor -> 3x 2’ XLR -> MC2 Amps -> NL4/NL2 -> Funktion One F1201/BR118
I am just looking for insight before heading back there with a full personal kit to try and isolate it.
It does seem to be a stronger in one of the 4 speakers but is super faint otherwise.
Thanks for your insight
