low recording level

These are generic adapters or “soundcards.” Some have microphone preamplifiers, some don’t.

These are the problems people have been having, usually with lower-end microphone systems. You can get a good idea of the typical shortcomings. “My microphone is too quiet!!”

And just because I haven’t thrown enough mud in the game, you know you have an omnidirectional microphone, right? Receives from all directions. They bill it as a News Gathering microphone, but many field operators are getting away from that type of microphone in favor of a very highly directional one.

You are going to need a very quiet room or area to record because that microphone will pick up sounds from all directions. Like the refrigerator, air conditioner, traffic outside, room echoes, etc.
