Had something I've never seen before. I installed my K10s and Alto subs into the venue and noticed one side had a mild buzzing sound. Changed out speakers, put on a ground lift, and disconnected the outputs to other speakers. Still buzzing. Finally, I had an 8 ft jumper cable, used to reach the long XLR cable. When I pulled it out of the speaker, I noticed one of the pins was pushed further back into the plug housing. I replaced the cable, problem solved. Usually, if a cable's bad there's no audio. Anybody else ever seen this before?
