At my theatre we have IR cameras in the house. I'm not sure what model they are. Money came through for an assisted listening system, and I don't really know what to get. I have heard that the IR systems are the best, but I am worried that the cameras will interfere with the ALS. So this is a 2 part question. 1. Will the IR cameras interfere with the system? and 2. What are the best assisted listening systems to get? Any insight you can provide would be great!!
