Hello everyone!
I've built a "talkback" box for use in a broadcast situation. The gist of the box is that there is a mic preamp that's connected to several push-button switches then to each channels output.
One thing I've noticed is that on one channel, there is a popping sound when I push the button. What's odd is that I don't hear it when I plug the output into my test speaker, but only when I connect to the piece of equipment that it's supposed to be plugged into. There is a definite pop and the meters spike.
One of my smart engineer friends recommended putting a capacitor on the switch. I'm all for it, but I want to make sure that I know I'm putting it in the right spot! Can anyone tell me which of these two designs would be the best way?
The input is the hot side of the unbalanced mic pre-amp, and then goes out directly to an XLR to be connected to my actual equipment. (It's not labeled well...)
Thanks for everyone's help!
