Blair Drummond Safari Park were looking for PA systems to cover massive areas within the park. These were to give talks about the wildlife and also to announce events and park closing times. The solution was four separate systems located in buildings around the park, with high powered radio receivers so the person doing the talk could be over 100m away from the receivers.
Thousands of meters of cable were laid around the park to feed the outdoor speakers along walkways and around enclosures.
