Portable MegaVox P.A. System. It is battery operated. It has a new battery and has a charger with it. It has an extension speaker. It has a wireless mike, but can be used with a wired mike. Two mike inputs and one in line for musical instrument or other device. The P.A. system can be used in multiple situations, in halls, on the ball field, in parades, in any kind of meetings & social groups, or for a musical group. It is very portable. The new ones called MegaVox Pro's cost $2,000.00. I will sell this for $500.00 or any reasonable offer before Oct. 20, 2013. Glad to answer any question if you leave a phone # or e-mail address.
