[QUOTE="Chris Nixon, post: 105110, member: 1947"] Re: Emergency/panic mute? Thank you Per, that's a much more detailed reply than I expected. :razz: It'll take me a while to get my head round that, I've only made very simple circuits before but the output shorting mute box has been in the back of my mind for a while so it might be a good motivation to learn more... If this was being used with varying consoles with differing output impedances, how much of a problem would that be? Is there much variation in output impedance? I'd like a 2 in 2 out box, maybe 3/3, a bit like a comms box or a DI, with toggle switches that have covers over them. Sorry for sort of stealing your thread. :D~:-D~:grin: On that topic though, would it be relatively simple to make one switch control multiple channels?
