So anyway, I am powering down my lair. It consists of turntable, crossfader, mixing desk, external sound card, pc etc. Everything is off (except for the pc). I notice that when I brush my fingers against the line in jacks (standard RCA) on any of the pieces of equipment (even the lines out on the turntable), a tingle travels up my forearm. This is new.
I am standing on a tiled floor in my socks. Both feet need to be touching the ground for this to happen. Standing in my slippers doesn’t work. If I make a complete circuit (if that is indeed what it is) between left and right lines in with, say, thumb and forefinger, it doesn’t work. Even if I just pinch one of the sockets with thumb and forefinger it doesn’t work.
What’s going on here? The feeling is kinda equivalent to putting your tongue on a 9V battery (I am pretty thick at times, but I’m not so stupid as to lick the back of my stuff, I promise). I just turned the stuff back on and it seems to be fine.
What will the consequences of my actions be (other than cheap thrills)? Am I likely to fry a squillion nt of hardware? Will the feeling one day cause my arrythmic heart to tick its final tock? What are the chances of a healthy blast of electricity sending me crashing into the living room (other than the ‘normal’ chances one takes with the electricity here)?
I am a dunce when it comes to these things, so if there is any advice it would be appreciated. I guess I need to earth this stuff?
