Questions Frequently Asked 

1. If there is no signal output when connecting the condenser microphone, please check if the phantom power supply is selected.

2. When charging lithium batteries with poor performance, their step-down circuit will interfere with the performance of the receiver.

3. When multiple devices are used simultaneously, improper frequency setting can easily lead to performance degradation due to intermodulation interference.

4. Some brands of MIC may cause interference due to poor signal shielding, which can be solved by using Cannon extension tubes.
