Instrument Microphone
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.
