Summary： The console is the control center for the lighting and sound system. Sometimes, if the high, medium, and low equalizers on the console increase or decrease by the same amount, it means that the sound system is not set up correctly. The system should be readjusted to prevent over-tuning of the console balancer. By paying attention to these details, many unnecessary problems can be avoided.

We all know that there are many kinds of professional equipment audio, and there will be many failures during use, but it is more troublesome to repair. This requires us to pay attention to maintenance during normal use. Let's follow Shijiazhuang professional audio to learn

1. Console problem

The console is the control center for the lighting and sound system. Sometimes, if the high, medium, and low equalizers on the console increase or decrease by the same amount, it means that the sound system is not set up correctly. The system should be readjusted to prevent over-tuning of the console balancer. By paying attention to these details, many unnecessary problems can be avoided.

2. The wireless microphone signal is unstable

Usually most audio projects are equipped with wireless microphones, but due to improper installation and debugging, a considerable number of applications are not good, especially in the performance site, the working conditions of wireless microphones will directly affect the quality of the performance, so this is a problem that cannot be ignored. Configuration: Minimize the operating interval between the transmitter and receiver, assuming that the frequency-adjustable microphone can switch to another channel.

3. The equipment shell is charged

The operation of the project requires electricity, so the problem of electrification of the housing of acoustic equipment often occurs during the commissioning of acoustic equipment. Although this is not a big problem, it can endanger the safety of employees in serious cases. All, this is not to be ignored. There are two common reasons: one is the moist air caused by the internal insulation or slight leakage of the power supply; the other is the induced current generated when the shell absorbs the electromagnetic wave generated by the power supply and other accessories.

The following are the precautions for using professional audio equipment:

1. If the equipment of the conference audio manufacturer runs under high input power for a long time, the voice coil may burn the speaker due to the temperature exceeding 100 degrees. Therefore, it is necessary to have the input power, that is, the rated input power, in order to ensure the normal operation of the speaker for a long time. This data will be given in the device data. Strict use is important. If the sound reinforcement effect is not ideal, the choice is to change the configuration instead of simply increasing the power.

2, improper use of special equipment, easy to cause howling. In order to reduce scattered sound and improve clarity, the active area of the speaker should be directed to the seat of the listener.

3, work often use multiple speakers at the same time. Pay attention to the polarity when connecting. All speakers should have the same polarity. If the connected speakers have different polarities, the sound output will interfere with each other, which sounds like low bass and obvious disharmony.

4, the power amplifier and audio equipment to match the power. The overall sound quality of the reproduced sound depends not only on the characteristics of the speaker, but also on the output and load characteristics of the amplifier. If the sound is not ideal, don't just think that there is a problem with the speaker, but first consider whether there is a problem with the amplifier system connected to it.

In summary, in order to avoid some problems that cannot be repaired, we must pay attention to maintenance during long-term use. The above is what I want to share with you today.
