[QUOTE="TJ Cornish, post: 43377, member: 162"] Re: Relay for life Pa system - suggestions. How much "pissing in the wind" will happen will literally depend on the amount of wind to piss in. I deployed Atlas Stadium horns on an 18' tower. With a dead calm and no audience noise, you can hear clear speech at the end of the course 2000' away with the tower running maybe 90dBA at 50' from the tower. With a 15-20 MPH wind it's basically gone after 600'. With a 50 MPH wind you have to crank it pretty loud to even hear it at 250'. What will work in your scenario will likely depend on how loud you can stand it being close to the speakers and how much wind you have. If that's not going to work, remote speakers are your answer. If you can run cable to your remote stations, that's going to be the cheapest and best option. Line level signals can travel a couple thousand feet with practically no loss, and cable is cheap. A stack of Mackie 450s and Honda EU1000s fed from a distribution amp or a bunch of auxes from your mixer would be a decent system. I'm not terribly up on RF links, but my understanding is it's a usual pick two scenario: fidelity, distance, simplicity/cost. If you don't care much about fidelity, you may be able to do a licensed 2-way UHF business radio. If you need high fidelity and/or the distance is more than the 300' - 500' range of the usual IEM links, then you are probably into some kind of licensed FM transmitter. [/QUOTE]
