Internal conditions are not conducive to receiving KTV microphone signals in several cases
The dead angle is a popular saying. It means that there is no signal in a certain place in the indoor place. People hold a microphone, and the range of walking is not large, but the signal is sometimes absent, which makes people very depressed. However, many people think that it is the quality of the KTV microphone. Not good, in fact, this is not all right, there are two reasons:
Reason one: Some indoor places do have interference sources. As the current communication tools are developed and diverse, such as mobile phones, walkie-talkies, cordless phones, etc., there are mutual interference situations, and there are metal equipment and glass reflections in the field. This will happen.
Reason 2: If there is a column or a large area of decoration blocking in the field, and the sound control room is far away from the venue, there is a wall blocking or turning a corner, etc., which will affect the normal reception of the signal.
How to solve this situation? There are two kinds of experience for your reference: 1. Sometimes you can change the direction, angle, etc. of the antenna to improve the receiving conditions. 2. Extend the antenna. This is a more emergency method. Take a video cable, about 10~15 meters. Remove the antenna of the original receiver and connect it to the video cable. Then install the antenna and you can test it. The place where the signal is received is sufficient.
