I have attempted to plug a mic into line in 3.5mm connection, but it does not seem to function.

Is there some setup needed?

I assume that you're using a Portable Hearing Lab. This hardware provides 3.1V voltage supply on the line in (pink). If that matches your mic specifications it should work.

The headset is a Roland CS-10 EM.
