These can take any microphone signal and give it a line level boost, which makes them important parts of virtually every pro audio setup. If your interface is pro grade, it can have mic inputs and hiz or instrument inputs too, so check if its the case and make sure you plug into the line inputs. The rxd line from the module goes to the sleeve of the 3.
I am working on a project to build a radiosoundcard interface, and a line out in the mic connector would be great. In this project, we will go over how to build a complete microphone circuit with an electret microphone so that we can make recordings with it. And while the basic purpose of a preamplifier is to boost a lowlevel microphone signal, there are plenty of other things to consider if you want to get the most out of your mic. If you need to use the sound cards more sensitive mic jack, see the mic schematic below for more information including a schematic that adds in a voltage divider circuit. Enable microphone, linein audio, and stereo mix in windows. We will begin with a single electret microphone and show the connections necessary so that we can do recordings with it.
