4、If the Vol ume C ontrol of t he re ceiver is s et to o high, it ma y over-drive t he input of
the mix er, ca using dis tor tion. Con versely, if th e receive r out put is set to o low, the
overa ll si gnal to noi se ra tio of the sy stem may be redu ced. Adjust the o utput level of
the rec eiv er such tha t hig hest soun d pressure lev el going into th e microph one c auses

Accor din g to FCC requ lat ions, wir ele ss microp hone operati ons are unprot ected

TIPS TO OBTAIN THE BEST RESULTS FOR A WIRELESS
MICROPHONE SYSTEM
1、If external antenna is used, low loss RF shielded cable should be used and the length of
the cable should not exceed 3m.
2、Do not place the receiver antenna within 1 m from another receiver or antenna.
3、The receiver antenna should be kept away from any metal surface.
