[QUOTE="Rob Timmerman, post: 147424, member: 172"] Re: Designing and making electronics for phantom power mic Mute is straightforward, as you can simply remove the DC ground reference and your mic will stop working. Volume control is a bit more tricky. There are a few ways to approach this. The simplest is to provide phantom power for your microphone after your mute box, allowing you to treat your signal as a pure audio signal without any additional DC offset. In this case, you could use pretty much any approach you'd like for both mute and volume. Even if you don't want to provide phantom power locally, you'll still need to remove and reapply the DC bias to the audio line. A resistive pad won't work, as it will also affect the phantom power.
