1. The supercardial capacitive directional microphone achieves high-quality sound pickup, and the replaceable microphone core is more suitable for practical use and maintenance.

2. The material of the microphone tube is all copper, which can achieve strong resistance to mobile phone signal interference.

3. The unit can be uniformly addressed through the host, or manually addressed and assigned a unit ID separately, making it convenient to add unit microphones at any time.

4. The unit is equipped with a replaceable 12V, 4000mAH lithium battery that can work continuously for 8 hours and has a standby time of 24 hours.

5. The unit has an OLED LCD display screen that can display various parameters of the current microphone.

6. The microphone has a red light circle. When the microphone is turned on to speak, the light circle will turn on itself, clearly displaying the current status of the microphone.

7. The detachable design between the microphone pole and the base makes the unit more suitable for transportation requirements.

8. When the microphone is turned on, the camera will automatically track it. When the current microphone is turned off, it will automatically track the microphone that spoke last. When all microphones are turned off, the camera will automatically return to the full range position.
