UBP800 BODY-PACK MIC TRANSMITTER
(Note: Observe care in selecting P.A. volume, transmitter location, and speaker placement so
that acoustic feedback (howling and screeching) will be avoided. Please also note the pickup
pattern characteristics of the microphone selected. Omni-directional mics pickup sound equally
from all directions, and are prone to feedback if not used carefully. Uni-directional mics are
more resistant to feedback, but best pick up sound sources that are directly in front of the mic.
Also, mics that are farther from the sound source, such as lavalieres, require more acoustic
gain and thus are more prone to feedback than close-source mics such as handheld models
that are used close to the mouth.)
For optimum performance, an INPUT VOLUME LEVEL (44) is provided. Adjust the gain by
turning the control with a small screwdriver. For lavaliere mic use, it is recommended that the
level be set at about 2/3 maximum. Experiment and set for maximum possible gain without
audible distortion on the high level peaks.
(Note: Turning down the gain too much can
compromise the signal-to-noise ratio and is
not recommended.)
