Wireless microphones can be disconnected for a variety of reasons. The channel may be occupied or interfered with. When using a wireless microphone, when the channel is interfered with by other devices or signals, the microphone will not be able to transmit sound properly.

Another possible cause is low battery power or poor battery contact. When the battery is low or the battery connection is not tight, the wireless microphone may be disconnected.

In addition, the use of distance can also cause wireless microphone frequency loss. If the distance is too far or there is an obstruction, the signal of the wireless microphone may become weak or disappear.

Therefore, when using a wireless microphone, you should ensure that the channel is free, and ensure that the battery is fully charged, and maintain the appropriate distance from the transmission device.
String frequency is caused by two sets of microphones with similar frequencies, just like the relationship between radio and radio, the more similar the frequency of the radio to receive the sound signal is stronger, your string frequency is equivalent to a radio two radios, which set of microphone string frequency to adjust its frequency to solve.
