Im looking for a version of this circuit (which eliminates the 'pop' caused by DC voltage powering an electret condenser) that works with a NO switch. The switch in the circuit below is NC. https://i.stack.imgur.com/MkDbu.png Is this possible? Im using a generic walkie talkie covert PTT mic, which I will terminate appropriately into a lectrosonics SMDB transmitter. (circuit diagram on page 11); http://www.lectrosonics.com/europe/phocadownload/SMB_E01_Series_Man.pdf Thank you in advance!! Rob |

Why not use a DPDT switch? One Pole can be used to provide the NO power switch and the other to provide the NC mute function. |
