Humey Whilem Posted March 21, 2009 Report Share Posted March 21, 2009 I'm trying to install a toggle switch (on/off) in my self built bullet mic, I've got a +/- toggle switch (two seperate switches but with one toggle, if that makes sense?) interrupting both the + and -.I had the wires going straight from the mic capsule to the out jack.The mic works fine when all wires are connected, gives a nice clean sound. However, I now have the switch in between, and it gives terrible buzz when I switch it off. I've tried switching the + and -, but that doesn't change anything, still buzzes when off. Any ideas? Help?

soundian Posted March 21, 2009 Report Share Posted March 21, 2009 Try putting + and earth on the switch instead of +/-. The buzz is an earthing issue so disconnecting the earth should fix it. Be careful though, try it at low volumes first in case you get a pop. Quote Link to comment Share on other sites More sharing options...
Humey Whilem Posted March 21, 2009 Author Report Share Posted March 21, 2009 I have 2 wires coming out of the capsule (black & red) so I dubbed them + and -. I tried putting a single switch to disconnect only one of the wires (so that only one of the wires would be diconnected when off), however this gave the same result: buzz when off.*starts looking for beginners audio electronics workshop* Quote Link to comment Share on other sites More sharing options...

Are you using an unbalanced mic in a balanced jack input? Quote Link to comment Share on other sites More sharing options...
Humey Whilem Posted March 22, 2009 Author Report Share Posted March 22, 2009 Sorry, I missed some vital points in your OP, like "self built" and "jack". LOL. It's an unbalanced mic, i.e. only a black & a red wire coming from the capsule. (Although strangely enough the mic it came from had the 3 pin OUT but going to a normal 1/4 jack.)It's now going to a 1/4 jack out. Quote Link to comment Share on other sites More sharing options...
Humey Whilem Posted March 23, 2009 Author Report Share Posted March 23, 2009 If anyone's interested, it's working as it should, I put a resistor at the unused pins of the switch. Dead quiet now. Thanks again!Here's the result: it looks pretty good and it sounds SWEET. Quote Link to comment Share on other sites More sharing options...
