Microphone Wireless G-MARK GD1.4 Professional UHF System Handheld Mic For Stage Speech Wedding Show Band Home Party Church

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.
