Problems solved by technology

[0003] The audio system mainly includes microphones, mixers, power amplifiers and speakers, etc. There is often a problem with the audio system currently in use: the person using the microphone starts to speak, but finds that the microphone cannot produce sound, which affects the quality of the performance, delays time, and appears This kind of situation is what the tuner is most worried about, but this kind of performance accident is hard to avoid, no matter how much preparation is done in advance, this kind of situation will still happen
[0004] The common reasons why the microphone does not make a sound are: the person using the microphone turns off the power switch of the microphone or the mute switch is turned off, the connector of the microphone connection is not in good contact, the battery of the microphone is dead, the power amplifier is not turned on, or although it is turned on, The main volume switch of the mixer is turned on too low, there is a problem with the connection between the power amplifier and the speaker, etc.
Although the tuner can do sufficient debugging work before the start, it is difficult to avoid failures due to the large number of people in an event, time constraints, and many people are not familiar with the use of microphones.
[0005] When the tuner tests the microphone, he usually inputs a sound signal at the microphone end, and then listens to see if there is any sound output from the speaker, but it is impossible to do this test after the program starts, and the tuner cannot detect the microphone leading to the mixer Whether the whole process is normal, so if there is a problem with the microphone power amplifier after the program starts, and it cannot be found in time, there will be a situation where the microphone and music cannot be played, which will affect the normal progress of the sound reinforcement, wasting time and affecting the effect. sometimes irreparable damage
