Optimal Separation of Multiple Microphones in the Same Room

If you’re using multiple microphones in the same room, the angles you face the mics will impact how much separation (or bleed) there will be between microphones.

Inevitably some of each individuals voice will be picked up by every mic in the room, but you want to minimize that bleed so that each voice can be more distinct and separated, and therefore more intelligible.

If you have 2 microphones: Participants should face each other and the mics should face directly away from each other.

If you have 3 microphones: Point the microphones 120 degrees away from each other.

If you have 4 microphones: Point the microphones 90 degrees away from each other.

If you have 4+ microphones: Good luck. The best advice I can give you is to MAKE SURE that each person is speaking REALLY CLOSE to their microphone.
