Standard Placement & Use Guidelines

1.Always point the microphone at the desired source of sound, and away from any unwanted sources.

2.The microphone should be located close to the sound source to minimize interference from other potential sound sources.

3.Use the 3-to-1 rule when using multiple microphones. Place each microphone three times farther from other microphones as from the desired sound source.

4.Minimize over-handling of the microphone to reduce unwanted mechanical noise.

5.Working close to the microphone will increase the bass tone and also provide increased gain-before-feedback.
