My new microphone is so quiet, it's an Aqta BM 800. I think I have not enough voltages for my microphone. Do I need a new power supply or is there a way or a soundcard with power cables so I can get the electricity separately?
I can't find any mention of an Aqta BM-800, but BM-800 is quite a popular name among microhones. Some of the other BM-800 come with a recommendation for a phantom power.
This one, I can't say.
