Vocopro UHF-388 Benutzerhandbuch

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.
