1, first test the distance to see if the distance is the same as before, if the gap is obvious, it is caused by signal attenuation, if not obvious. It could be interference.
2. In view of the problems caused by signal attenuation, you can increase the host antenna, adjust the antenna Angle, check the antenna interface, etc., and check whether the SQ value of the host is set too high.
3, the cause of signal attenuation is also divided into environmental effects and single machine failure. When testing the distance, test multiple machines, if there is a big gap between them and the previous, generally adjust the antenna Angle and increase the height of the host can get good results, if it is a single host, you can check whether the antenna interface is damaged, and check whether the host SQ setting is normal.
4, if the frequency is interrupted by interference, there will be no significant distance shortening in the test. But this fault is often mixed in with the phenomenon of signal attenuation. So it's hard to tell the difference.
Therefore, you can judge by turning off the hand and observing the host signal indication. In the site of signal interference, the host antenna signal indication will flash, and when the host chooses different frequencies, it will be obvious that there are more channels with interference. This time. Only need to adjust according to the way of mixed debugging of multiple microphones, and basically can eliminate the fault.
5, wireless microphone is the use of radio frequency signal for audio transmission of a device, due to the characteristics of wireless signals, there is no absolute security. Therefore, in the process of use, we should master more relevant knowledge in order to better use the equipment. It is a very unscientific approach to put hope only on the performance of the equipment.
1. Check the battery: Replace the battery and ensure that the battery is fully charged.
2. Check the antenna: Adjust the antenna position to ensure that the distance between the antenna and the receiver is not too far.
3. Check the signal transmission: Ensure that the signal transmission between the receiver and the wireless microphone is normal. Try repairing the wireless microphone and receiver.
4. Check the environment: If the wireless microphone is used in an environment with high interference and weak signal, the signal may be interrupted. You can try moving the wireless microphone to a more suitable position.
If the above methods can not solve the problem, it is recommended to contact professional audio equipment maintenance personnel for maintenance.
