Yes, seen them, though would never logically associate a switch called "external amplifier" with toggling the output mode of some socket. I might imagine it changing whether a master volume level controlled one thing or another. Or that a sound board with an in-built power amp for driving speakers might toggle between speaker-out or line-out. It's a strange name, and the lack of explanatory documentation doesn't help. -- Test running FC6 & FC5, and still using FC4. I delete all private mail, unseen. I read from the list.
