Reasons for no signal from wireless microphones in general KTV audio equipment:

1. The signal reception conditions in the KTV box are not good

If there are pillars blocking the venue, and the sound control room is far away from the venue, there is a wall blocking or turning around, etc., it will affect the normal reception of the signal.

2. There are interference sources in the KTV venue that affect signal reception

Today's communication tools are developed and of various varieties, such as mobile phones, walkie-talkies, wireless phones, etc., which all interfere with each other, and the reflection of metal equipment and glass in the field will also cause this situation.

The solution to the no signal of KTV wireless microphone:

1. You can change the direction and angle of the antenna to improve your receiving conditions.

2. If the reception conditions are more severe, such as the sound control room is not in the venue, or there are pillars, walls, etc., the problem can generally be solved by extending the antenna. The emergency method is as follows: take a video cable, about 10- 15 meters, remove the antenna of the original receiver (or buy an antenna by yourself) and connect it with the video cable, and then install the antenna in the place where you have tested and can receive the signal.

3. You can try a different set of frequencies, because some interference sources may just conflict with the frequency of this set of microphones, and changing a set of frequencies can often solve the problem. If the receiving environment such as a column is not very good, try to buy the one with single transmitter and double receiver (that is, one microphone and two antennas), because the receiving range of the two antennas is large. The two yellow lights of the machine are on, indicating that it is in all directions; if the yellow light on the left is on, it means that the left receiving antenna is within the speaking range on your left. The light turns on immediately, and the antenna on the right works immediately. This ensures that your speech is received in all directions.

4. If the receiving environment is too bad, you can choose a multi-frequency adjustable wireless microphone.

The above are the reasons and solutions for the lack of signal in the KTV wireless microphones organized by Jazz Dragon professional audio manufacturers.
