Microphone basics
Microphone Position
The UHF-5805 is ideal for close-up vocals and can be held in the hand or mounted on a mic stand. The most
common applications and placement techniques are listed below. 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 in. from the microphone, the microphone boosts bass frequencies (by
6 to 10 dB at 100 Hz), creating a warmer and richer bass sound than when farther away. This effect, known
as proximity effect, happens only in unidirectional dynamic microphones like the UHF-5805.
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 condi-
tions: placing loudspeakers too close to microphones, having too many open active microphones, boosting
tone controls indiscriminately (mainly treble) and 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. Each time this distance is
