Plugging Video into Audio Damage?

[erik343]

I accidentally plugged in a video signal into the audio port on my Framemeister. Will this cause any damage?

Fairly certain the voltage ranges of a standard composite video signal (0-0.7v) is within nominal range of line-in audio (0.7 to 2v)

As a kid I accidentally plugged video into audio and vice-versa many times when swapping consoles on the TV. No damage at all. The voltages are similar enough there won't be an issue, which makes perfect sense since they'd have been designed around the knowledge that consumers would eventually plug the audio into the video by accident or vice-versa due to them having the exact same connectors. It'd be bad design for it to cause your TV to explode or something if you accidentally messed up which connector was which and if it did they would have made the connectors proprietary so the wrong one can't be plugged into the wrong socket.

What will destroy hardware though is plugging in a JAMMA connector upside-down. There's nothing that will prevent you from doing that and it tends to kill the PCB or severe component damage as high voltage goes to components that aren't meant to take that amount of input voltage, and they didn't make the JAMMA connector in such a way that accidentally putting it on upside down wouldn't cause this, in part because JAMMA connectors were only really for arcade operators to deal with and weren't really accessible to the general public!
