LWD-14A Wireless Microphone Transmitter Receiver System Mini Lavalier Mic for Interview Video Recording

• Use UHF676 to 697MHz frequency band (channel A: 677-686MHz; channel B: 687-696MHz), strong anti-interference

• Adopt 24Bt48KHz high-performance audio dedicated A/D and D/A processing

• Use ID code + frequency for data encryption and frequency (even if the same frequency is used, when the receiving chip is interfered by RF, it will only affect the receiving distance, and there will be no interfering noise. If the two receivers are separated by a certain distance(for example, 10 meters), you can consider frequency reuse

• With automatic mute and impact elimination circuit to avoid the impact and noise of switch machine

• The microphone has an LED digital tube display function, which can intuitively display the current frequency

• Wireless transmission effective distance 30-50 meters

• The microphone is designed with a lithium battery circuit and has overcharge and overdischarge protection

• The simple operation interface and few adjustable parts can completely avoid malfunction caused by misoperation

• The transmitter has a low-voltage detection function. When the battery voltage drops to 2.2V, the battery character flashes

• Very high pickup sensitivity, excellent sound quality, so that you can speak or sing easily

• Multiple devices can be used at the same time without interference and frequency channeling

• With power and wireless indicator lights

• Support single frequency
