Adjustable frequency: 
Dual UHF wireless lavalier microphone system, optional frequency: 520-560MHz. The phase-locked loop frequency synthesis technology is adopted to provide barrier free sound transmission, minimum loss and maximum feedback suppression. Smooth and fast infrared synchronization. Remote operation of 100 ft – 150 ft line of sight.
Anti interference function: 
The wireless bodypack microphone is equipped with an automatic scanning function to enable the system to search for the channel with the least interference, so as to pair with the transmitter. The dual antenna design improves the anti-interference ability and reduces the interference between each channel.
Lavalier (headset)microphone is easy to use, plug and play, automatic pairing: 
Only insert the receiver into MIC jack, not AUX jack. Then turn on the entire system and the receiver will automatically synchronize its frequency with the microphone. Adjustable volume control. It is very suitable for indoor, outdoor, party, church, meeting, wedding, speech, classroom, opening ceremony, promotion, stage small live performance, professional participation or religious activities.
