7000SA true diversity one to two wireless microphone
Performance Series
This is a true diversity one to two wireless microphone with a professional grade true diversity line, which can be used for longer distances, better sound quality, and better suppression of howling. Suitable for outdoor performances, commercial events, lecture halls, and other settings.
Product Features:
1. High end true diversity pure analog circuit solution: adopting a built-in dual receiving module design, the receiving antenna is integrated into one, which is convenient for installation, layout and use;
2. Configure capacitive and dynamic microphone cores for easy interchangeability in different scenarios;
3. A brand new audio circuit architecture with strong mid to low frequencies, transparent mid frequencies, and clear vocals, providing perfect expressiveness in the details of sound;
4. Equipped with a lock screen function to prevent accidental operation;
5. Using UHF frequency band and phase-locked loop (PLL) frequency synthesis;
6. The superheterodyne secondary frequency conversion design has extremely high receiving sensitivity and super strong dynamic tracking ability, making it easy to pick up and receive sound at long/short distances;
7. The first intermediate frequency adopts a sound table filter, and the second intermediate frequency adopts a three-stage ceramic filter, which greatly improves the anti-interference ability;
8. The receiver is equipped with a high-end LCD screen and a metal microphone tube, which is resistant to drops and durable;
9. Equipped with one click infrared automatic frequency matching function, it can quickly synchronize the microphone to the working channel of the receiver;
10. Equipped with long-distance power regulation;
