UHF 642.2~660.8Mhz 1 To 4 Professional Wireless Conference Lapel Microphone

Description: Several new domestic unique technologies are added on the basis of the original microphone technology, which makes the system have ultra-high sensitivity, strong anti-interference ability and good stability. The original technology includes high-efficiency low-cost RF emission technology and SMT production process in the United States, and uses a locking frequency of better than 10ppm quartz crystal, dynamic o compression, expansion circuit, image frequency suppression circuit, switch-time shock elimination circuit, anti-return circuit variable output control technology, computer EDA, analog online auxiliary design, etc. Features: The system have ultra-high sensitivity, strong anti-interference ability and good stability because several new domestic unique technologies are added on the basis of the original microphone technology. It can be used as soon as it is booted because the frequency point is fixed, more convenient. The volume of four channels is independently adjustable, which provides 1+4 o output, and the four-channel o output is independently controllable. The conferencehandheldcollar clips in the transmitter can be mixed and matched to use. Stackable machine, 5 sets of different frequency points can be used at the same time.
