we are all familiar with the 3.5 mm input and output jacks on every computer since the late 80s. However, some of these inputs are only made for certain types of plugs. They all have a colored ring around the plug. Depending on the device it can be one or three rings. Headphones, for example, have two rings indicating a left and right audio channel.

My R16 microphone input doesn't give me any detail about what kind of plugs it supports. Some cheap microphones come with one ring. My lapel microphone has two rings. I've also seen plugs with three rings, but I'm not sure exactly what they are used for.

What kind of plug does the Jack on the microphone input support for my computer? Do I have to use one with 2 rings? You can often plug ANY of these into a Jack. The worst thing that happens, your device doesn't work. Picture just for attention and a little bit of reference.
