can this be used with a dynamic microphone.?I do not want any dc voltage on the line.

Yes. Dynamic mic's are fine. It's what we use for our diver comm system in a research aquarium. I feed the divers mic's to a multi-input mixer from these Rolls preamps.

What size dc adapter does this unit use?

comes with its own ac adapter, -15 volts.

Why does my mic clip as soon as I plug the mp13 into PC mic in?

It sounds like your level into the microphone input on your PC is too high. You would not normally need a preamp to feed a microphone input. The levels out of the preamp would be too high. The preamp would typically be used to feed a line input. If you need to raise the level into a microphone input you would not want very much gain.
