HO HUM, HO HUM. I did another family gathering, good thing it wasn't a paying gig. Terrible hum coming thru the PAs. Directly from the sound card channel. When I turned the mics down, it didn't go away. When I turned the channel slider down, it went away. This was with the Behringer. I took the Behringer out and used the 1/8 to dual 1/4 cable in so sound was coming directly from the laptop internal card. Hum still there. I tried switching channels. Same hum. What gives? As long as the music was going, tough to notice. But if the music was at a part of the song that was low, or between songs, very noticable and very annoying. I need to have this figured out before I contract out. Please help!
Was there a satellite or cable system connected to the TV hooked to your laptop? Dollars to doughnuts that was the source. If you had disconnected the coax hooking that in, I am betting it would have disappeared.
