\u25cfIt adopts a dual-channel single-receiving system with a combination of four antennas, and has developed a unique high-sensitivity diversity selection circuit with excellent anti-interference performance and strong signal reception ability, which can minimize the occurrence of frequency disconnection.
\n\u25cfDual-channel independent AFS frequency automatic search function, which can quickly scan the frequency with the least interference in the working environment and lock it.
\n\u25cfProfessional performance-level phase locking circuit, combined with noise locking squelch control and digital pilot technology, when the transmitter is turned off, the pilot control mutes the AF signal to suppress noise, and at the same time mutes the corresponding receiver.To ensure the effective blocking of interfering signals.
\n\u25cfThe backlit LED display indicates the RF and AF signal strength, battery status, diversity channel indication (A\/B), frequency, frequency group\/channel and other working status.
\n\u25cfThe SQ receiving distance is adjustable from -65~-100dBm, and it has an operation lock key function to prevent misoperation.
\n\u25cfIt has a high dynamic response and a wide frequency response, which eliminates the noise caused by high frequencies and achieves excellent sound quality.
\n\u25cfSelf-developed core technology \u201cVCO and radio frequency circuit” to make the available bandwidth larger and the signal reception more stable.
