For the audio often used on the stage, there may be problems such as circuit failure, audio squeal, current balance, signal distribution, and abnormal voltage limiter. Next, Shandong stage audio manufacturers will talk about how to solve the problem of stage audio squealing.
The rear signal of the pusher should be taken to avoid the microphone howling due to uncontrolled effect, and the return can occupy a channel conditionally, which is more convenient for debugging. If there is noise in the audio equipment, first check the dimming interference and whether the audio and light power supplies are disconnected.
Next, check whether the light power supply and control line are too close to the audio signal line, and whether the silicon box is too close to the audio equipment.
Generally, the noise of the speaker system is caused by the unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal grounding is incorrect, the noise interference is likely to occur.
If resonance and acoustic feedback occur in professional audio equipment, first check whether there is a peak in the room frequency response, and then check whether the room structure and decoration are reasonable. It is recommended that you also check whether the frequency dividing point and bass gain are reasonable, and whether the room reverberation time is too long.
If there is a problem with the stage sound, the performance will not go smoothly. Therefore, we need to know what problems stage acoustics may encounter, and take effective measures to prevent or solve these problems.
Facts have proved that if you want to avoid problems with stage acoustics, you should know how to use and maintain the acoustics so that they are not damaged. Only in this way can we really experience the wonderful sound from the stereo. Follow us http://www.opensourceagility.com , learn more about audio problems!
