- SKM-9000 True Diversity Wireless Microphone
Features
1. Use of UHF740-790MHz frequency band, to avoid interference frequency, flexible and simple operation
2. True diversity design, four super-strong antenna connection mechanism, through the connection barrier.Operation is flexible and simple
3. Infrared automatic frequency, so that the transmitter and receiver automatically synchronously send and receive.
4. PLL phase locked loop frequency stabilization system, providing 200 channels
5. Using the latest high-frequency filter, maximum filtering out-of-band interference signal.
6. Use of secondary frequency of the high-frequency circuit design, with high sensitivity.
7. Multiple Squelch Control Circuit, rejected external interference reception distance of 180 meters.
8. Specially designed voice compression expansion circuit, greatly improve the signal to noise ratio.
9. Unique circuit design, dynamic large, wide frequency response, low noise.
10. Fashion color design, built-in 60 groups of frequency modules, simplify the user FM program.
