DJ Tips in over a minute: Bluetooth and wireless microphones

DJ Tips in over a minute: Bluetooth and wireless microphones. Was having a problem with my wireless microphone during ceremonies, sounded like it shut off when the officiant wasn't speaking? No issues after the ceremony so my son said he thought maybe it was Bluetooth from his iPad he was using for the ceremony, and when asked he did find that it was on. Then yesterday the same thing until I asked the pastor to put his iPad on Airplane mode and the issue went away!
