UHF-502-B Tips: When two different frequencies using a wireless microphone transmitter close to one for two, it will produce distortion harmonic interference in tune, the closer or more frequency, the more severe the interference microphone, in Multi-channel systems used simultaneously, problems will interfere with each other and receive more severe instability. Hanging waist, wearing a lapel tips: microphone pickup is a low impedance output and electro-acoustic instrument pickup, compared with a high-impedance output (microphone for 0DB output, mic for acoustic instruments -20DB output) KTV stage microphone, so electronic musical instruments should be used to LINE / MIC (line / microphone) switch on the wireless transmitter, set to LINE (line) position; while the corresponding transmitter properly adjust the gain to adjust and control the excesses of distortion level .
