Now..unless the band is coming from a country that has 220V, their equipment is going to run on, and require 110V.
As far as I know, all central american countries are 110V.
I'll be here if you need further help with this issue. Please let me know.
Thanks. I just wanted to make sure that speakers and amplifiers do not require 220. Do you know about this?
Yes, I know a lot about this. You are in Nicaragua. The voltage there is 110V as it is here in the US. I have several friends in bands and none of them have equipment that requires 220V. I myself have several electronic keyboards and amps and none of them require 220V.
