For a warmer sound with increased bass presence, move the microphone closer. • Do not cover grille with hand. Wearing the Headworn Microphone • Position the headworn microphone 13 mm (1/2 in.) from the corner of your mouth. • Position lavalier and headworn microphones so that clothing, jewelry, or other items do not bump or rub against the micro phone.
Shure Incorporated Adjusting Gain Monitor the audio LED indicator on the receiver front panel when setting the transmitter gain. • Green: normal levels • Red: excessive sound levels (overload). The red LED should only illuminate infrequently when you speak loudly or play your instrument loudly.

If the receiver audio LED flickers red often, set the microphone to attenuated. Use the channel button to change the gain setting. 1. Hold down the channel button for 5 seconds. A dot appears on the lower righthand corner of the LED display, which indicates −10 dB gain setting has been activat ed. 2.
