Umm, I think you're confused. Recording is the art of playing a recorder:

General rule of thumb:

Audio interfaces should be set to line input.

If given the choice, select + 4, otherwise, it may be designed for -10? Most outboard microphone preamps are designed to deliver an average level of + 4 DB output with headroom to +18 to 28. Way to hi for a -10 sensitive input. if that is the case? You may need to purchase an outboard/in-line pad, from companies like Shure?

Your microphone preamp should have some type of metering built into it? Of course, you will adjust level for proper signal on its own internal meter. If the outboard microphone preamp has an output level control, you'll adjust that after you have tweaked your microphone level for proper indication on the preamp. It's only after that step that you will adjust the input level on your audio interface.

That's the way it should be done.

thank you, i appreciate your help now things are clear. but now i need to now how things are connected. if the mic goes to the preamp and the preamp to the sound card and the sound card to the computer.

What sound card is it?

This is one of those questions with the "potential" that is being discussed over @: {old-link-removed}
