The reception was separate from the wedding. I had gone over way early to setup and everything was peachy as usual. I go grab a shower, dinner & chill to get in the mental zone and return to the reception hall. I power everything back up & a hard static is blaring through all the speakers. I'm thinking interference of course from the venue somewhere so I start scouting things out because I've already sound checked my system earlier. Unplugged everything else on the venue; nothing. They had setup a photo booth across the room so I checked that; nothing. It was now about 20 min before guests were to arrive so I decided to send out the distress call. I decided to walk myself through setup 101 in my head & began to go through my setup again checking everything over. When I got to my laptops, I unplugged the Dell XPS & static went away. Shocked, but relieved I quickly changed it out for the the backup & all is well. It wasn't the Hum-X so I'm thinking it's in the cord/battery. Static through the Hum-X sounds strange doesn't it? Haven't had time to check into it yet. Always have backup laptops; I carry 3. Any thoughts???
