We have classrooms that have a CCTV camera and sensitive wall mounted room microphone connected directly to the rear of a DVD recorder which is in turn connected to a TV. The idea is that meetings in the room can be recorded to DVD. The problem is that the Mic is ON the whole time. Therefore the TV audio must be kept down otherwise we get feedback through the TV speakers. This is a pain because when they want to play back the recording the audio is turned up. When they press stop without turning the audio down again on the TV the mic will feedback. Any ideas on how to prevent this. Without having too much user intervention. ie not physically turning the mic off and on.
