Product description
Parameters
Product Features
●Using UHF frequency band, digital electronic circuit, stable characteristics.
●Pure automatic signal selection and reception, using [tone code, noise lock] dual mute control, when the transmitter is turned off, the pilot tone mute can eliminate RF interference.
●Microphone head replacement function: Separate sound head module structure.
●Electronic potential volume adjustment.
●TNC standard antenna base, can provide active antenna amplifier bias, connect to the antenna system, increase the receiving distance and stable receiving effect.
●Automatic frequency search: Through the automatic search function, you can automatically search for an idle carrier frequency (in the case of interference).
●IR infrared automatic frequency matching function: complete the wireless synchronization of the transmitter through the infrared interface.
●The real-time status of the transmitter can be displayed on the receiver, for example (real-time battery status).
●Receiving effective distance: 150 meters in a straight line without obstacles.
