[Note: Observe care in selecting P.A. volume, transmitter location

and speaker placement so that acoustic feedback (howling and screech-
ing) will be avoided. Please also note the pickup pattern characteristics of
the microphone selected.  Omnidirectional mics pick up sound equally
from all directions, and are prone to feedback if not used carefully.
Unidirectional mics are more resistant to feedback, but pick up sound
sources best that are directly in front of the mic. Also, mics that are
farther from the sound source, such as lavaliers, require more acoustic
gain and thus are also more prone to feedback than close-source mics
such as handheld or headworn models that are used close to the mouth].

For optimum performance, an 

INPUT LEVEL CONTROL (27)

 is provided.

Adjust the gain by turning the control with your thumb. For lavalier mic
use, it is recommended that the level be set at about 2/3 maximum. For
headworn mic use, it may be advisable to turn the gain down somewhat,
depending on the volume levels expected.  In either application, experi-
ment and set for maximum possible gain without audible distortion on
the high level peaks. 

(Note: Turning down the gain too much can com-

promise the signal-to-noise and is not recommended.)

The 

AF PEAK LED INDICATOR (3)

 on the UHF 10 receiver will light for all

loud input signals. Occasional flickering on and off during use is normal,
but if the LED stays lit continuously, turn down the 

INPUT LEVEL CON-

TROL (27) 

on the UB-10 transmitter, or noticeable distortion may result.
