Hello, my name is Terrance and I am a member of a non-profit group that holds a haunted house each year to raise money to support the local youth. We are looking to upgrade our audio effects system from an ipod and a home theater system with extra speakers spliced in. We have about $1000 to spend and we would like something that can play 3 or 4 different tracks in different locations at the same time. I really don't know where to start with all of this so any advice would be great, thanks!
