1. Equipped with a high-grade LCD screen, it displays the operating status of receivers and transmitters clearly and intuitively for real-time equipment monitoring.

2. Operating on UHF frequency band of 640–690MHz with selectable multiple frequency points, it efficiently evades interfering frequencies and guarantees stable signal transmission.

3. The main unit supports one-touch frequency scanning to quickly locate interference-free frequencies and eliminate crosstalk caused by same-frequency overlap.

4. Built-in one-key lock function prevents unintended misoperation and maintains consistent equipment performance.

5. Featuring automatic infrared frequency sync technology, the transmitter automatically matches and calibrates its frequency with the receiver via a single press on the main unit for user-friendly operation.

6. Conference microphone bases support three power supply options: power bank, AC adapter and AA batteries for flexible configuration as required.

7. The effective pickup distance ranges from 50mm to 80mm, satisfying sound collection requirements for diverse usage environments.
