Calculating Phase Response for 2 microphones given the input

3. Can you run two microphones off the same channel?

What happens when you put two microphones together?

If two microphones are used on the same frequency at the same time then they will interfere with each other because the receiver cannot distinguish between different signals and cannot separate them out into separate signals. In a situation like this neither signal will come through correctly.

What is the 3 1 rule of microphone placement?

This rule deals with minimizing the audible phasing problems when summing several microphones to mono. The rule states that the source-to-microphone distance of numerous microphones should be three times the distance between the sound source and the nearest microphone.

Can you run two microphones off the same channel?

In music, recording, or conferencing applications, it is not recommended to parallel microphones into a single mixer input.
