True diversity wireless microphone

◆ The new concept of digital frequency guide technology, completely solve the mutual frequency crosstalk phenomenon 
◆ Configured with whistle suppression circuit, debugging easier 
Automatic search for non-interference channel function, more convenient installation 
UHF frequency band, phase-locked loop (PLL) frequency synthesis
100×2 channels, channel interval 250KHz
True diversity ultra-differential secondary frequency conversion design, with high reception sensitivity
RF part adopts multi-stage high performance RF filter, with excellent anti-jamming ability 
The first IF adopts sound meter filter, and the second IF adopts three-stage ceramic filter, which improves the anti-jamming ability very well.
◆ The microphone uses the No. 5 battery, which is easy to purchase, with a duration of 8 hours.
◆ The microphone adopts a unique double-boost design, the battery power drop does not affect the overall performance of the microphone 
◆ Ideal environment operating radius of 150 meters or more, suitable for various requirements of the occasion
◆ Handheld configuration with LCD display, aluminum alloy microphone tube body 
◆ With four adjustable transmitting power, flexible to adapt to various scenes
◆ With infrared automatic frequency matching function, the microphone can be quickly synchronized to the receiver's working channel 
True diversity reception, using dual antennas, dual reception lines
◆ Good restoration, true diversity, reception distance up to 150 meters away, suitable for large multi-function hall, performance, and some high-end venue
