Bad signal quality at the receiver. There are also a lot of reason can bring poor quality. wireless microphones always use digital transmission technology such us UHF、2.4G、bluetooth、Wifi. Is not like the traditional technology, you can't see a slow degradation as the signal quality drops, it just suddenly doesn’t work no choice.
There are several reason to cause your wireless lavalier microphone to suddenly cut out as below:
1.You should check you device whether losing output power or not. Can even completely shut off. Usually a battery problem.
2.More path loss between transmitter and receiver. This can be from orientation of the antennas changing or something blocking the path.
or some other wireless microphone system effect the path.
3.Interference. As you can't ensure your operation environment is clean,as many RF signals will be arround you.
4.And the number one cause, multi path. When a signal is sent from one location to another there are many paths the signal can take. There is usually the direct path and almost always many other paths where the signal bounces from point to point. The result is the receiver sees many signals at many different times, phases, and power levels. This causes the small area where a receiver can determine the correct data (called the eye) to shrink. When the eye gets small enough the receiver looses sync and the data transmission is lost. The receiver has to re-sync (if it can) to start over. Note this is the same problem caused by interference and in practice it is often a combination of interference and multi path that causes the loss.
5.The wireless microphone system connection cable didn't connect successfully,will bring it suddenly cut off.
If you have such a trouble I will recommend you to buy our lensgo348c wireless microphone.would be the best choice for you.cause it have Tf card in the transmitter so that your voice will never lost.
