U-666 WIRELESS MICROPHONE

Application:

Description:

1. Use HF740-790MHz frequency band to avoid interference frequency. 2. Flexible and simple operation. 3. Fully automatic infrared frequency matching, which makes transmitter and receiver receive and receive automatically synchronously. 4. Using PLL frequency synthesis and stabilization system, 120 channels are provided. 5. Use the latest high frequency filter to filter out the out-of-band interference signal to the greatest extent. 6. High-frequency circuit with secondary frequency conversion is designed with high sensitivity. 7. Multiple noise control circuit, reject external interference 8. The specially designed speech compression expansion circuit greatly improves the signal-to-noise ratio. 9. Unique circuit design, large dynamic, wide frequency response, low noise. 10. Fashion color screen design, built-in 60 sets of frequency module, simplify user FM program.
