Performance characteristics:

1. Four microphones can be interchanged, and the microphones use all aluminum metal tubes (without any plastic), which are durable and have more stable performance;

2. Standard 1U chassis, with a panel made of 3mm aluminum metal and a chassis made of 1mm metal;

3. Standard 3C power supply, in compliance with government and enterprise project standards;

4. 4-channel UHF wireless system with 50 selectable frequencies per channel;

5. Equipped with LCD display, providing real-time feedback on the system's working status;

6. Adopting digital audio code locking technology to effectively block noise interference in the usage environment;

7. Adopting the latest infrared automatic frequency matching (ACT) technology, setting and operation are more convenient;

8. In an ideal environment, the effective working distance is about 80 meters
