tions. [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.
