True diversity a tow used to hold ACT-520 Product parameters
Function introduction:
1. UHF ultra-high frequency band is adopted, which has less interference and reliable transmission than the traditional VHF frequency band.
2. Advanced digital ID pilot technology is used to completely eliminate the phenomenon of cross-frequency.
3. Advanced 048-bit symmetric encryption algorithm is used for wireless signal, which prevents eavesdropping.
4. It has the latest dual backup function of handheld waist bag one- conversion.
5. True diversity reception technology is used, the receiving distance is farther and more stable, and the effective using distance is 500 meters.
6.elligent wireless signal field strength FI detection, real-time monitoring of the interference status of the frequency used.
7. It has the function of one-key automatic search for clean points, one-key lock key function, and infrared frequency matching function.
8. 30-level electronic volume control is used, which is concise and accurate, 00 groups of optional frequency points, and the microphone is optional and universal.
9. The battery consumption of the receiver and the transmitter is displayed synchronously, and the battery automatically turned off when the low voltage of 1.8V blinks.
10. The line design has the function of feedback howling suppression and weakening, which effectively reduce the feedback howling.
11. The microphone has a high-strength anti-mobile phone electromagnetic wave interference design, which can eliminate the noise interference of mobile phones
12. Good sound quality, high sound fidelity, suitable for large and small stage performances, large and small conference rooms, multi-function halls, etc.
