Behringer Xenyx 1002B .. battery powered mixer .. I had an earlier version many years ago ... Behringer Xenyx 1002B MixerOh...It's a 10 inch Sub...Well, if I were using ADJ 8 GO BT or 10 inch Powered Pyle Speakers, I guess a 10 inch battery powered Sub would compliment those nicely. It might provide enough bass for dancing at a wedding along with those 10 inch pyle speakers. Hook up a power inverter to keep them going once batteries get low. Should be able to provide sound for a 5 to 6 hour event by doing this!
Put 4 ADJ GO Tri Par Lights on a light stand, and set them to sound active, or DMX, and that is your light show! NO WIRES!
Now we just need a battery powered Mixer, and battery powered wireless microphone systems. Didn't Shure have a line of Mic receviers that were battery powered?
