The distance between the microphones does not matter. It depends on the distance between your microphone and the speaker. If he is too close and the room is small, he will chirp loudly. Principle: Every time a sound comes from the speaker, the speaker vibrates to the microphone after being shocked, and the electricity is transmitted to the power amplifier for further amplification. The amplified electricity drives the speakers. The chirping sound it produces in such a rapid cycle. The principle of a microphone is the same as that of a loudspeaker. When there is sound, it vibrates and emits weak electricity.
In a computer, the independent sound card can use the same jack if there is one. a physical mixer, it won't work.

It can power your cond microphoneensor and use a dynamic microphone. . If you turn on the 48V PHANTOM, your dynamic mic will be fried.
