Microphone Position
The UHF-388 is ideal for close-up 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.
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:
Microphone Basics
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.
Request that the talker speak louder into the microphone.
Reduce the distance from the talker to the microphone. Each time this distance is halved, the
sound system output will increase by 6dB.
Reduce the number of open microphones.
Move the loudspeaker farther away from the microphone. Each time this distance is doubled,
the sound system output can be increased by 6dB.
Move the loudspeaker closer to the listener.
Use an equalizer/feedback reducer to cut the frequency bands in which the feedback occurs.
What to do if feedback occurs before the sound system is loud enough?
Microphone Placement & Tone Quality
Lead & Backup Vocals
Lips should be less than 3” from or even touching the windscreen on an axis to the microphone.
Doing this creates a robust sound, emphasizes bass and provides maximum isolation from other
sources.
Speech
When giving a speech or simply speaking, place the microphone 4” to 10” away from the
mouth, just above nose height for a natural sound with reduced bass. You can also place the
microphone 8” to 16” away from the mouth, slightly off to one side, for a more “distant” sound
with highly reduced bass and minimal “s” sounds.
