MICROPHONE BASICS
Microphone Position
The device is ideal for close vocals and can be held in the hand or mounted on a mic stand.
Keep in mind that microphone technique is largely a matter of personal taste, and there is no one
"correct" microphone position.
Proximity Effect
When the sound source is less than ¼" from the microphone, the microphone boosts bass
Frequencies (by 6 to 10 dB at 100 Hz), creating a warmer and richer bass sound.
Feedback
Feedback occurs when the amplified sound from any loudspeaker reenters the sound system
through any open microphone and is repeatedly amplified.
Most commonly, feedback is caused by the following conditions:
• Placing loudspeakers too close to microphones.
• Having too many open active microphones.
• Boosting tone controls indiscriminately (mainly treble).
• Performing in areas with high ratios of room surfaces that have hard and reflective surfaces
such as glass, marble and wood.
¿What to do if feedback occurs before the sound system is loud enough?
• Request that the talker speak louder into the microphone.
• Reduce the distance from the talker to the microphone.
• Reduce the number of open microphones.
• Move the loudspeaker farther away from the microphone.
• Move the loudspeaker closer to the listener.
