ArtistsRifles Posted October 5, 2006 Share Posted October 5, 2006 OK - a low voltage mic. Too big to be a throat mic so must be used in some other specialised application. 9 feet of cable is a fair old length - maybe some form of audio surveillance device???

ArtistsRifles Posted October 8, 2006 Share Posted October 8, 2006 Yup. Does anyone know if TOBIAS is still used? This isn't part of the quiz, I don't know the answer. Don't believe so - I seem to recall a US based system being brought in during the late Eighties/Early Nineties.............. I'm open to correction here though!!!
