insights from stage equipment merchants on how audio equipment is maintained and used.Small meeting

　　The normal holding of an event is often inseparable from the audio equipment on the stage, because if there is no audio equipment, then the event will definitely not have any warm atmosphere at all. Therefore, audio equipment plays an irreplaceable role in the holding of stage activities. Therefore, there are many things that the organizer must pay attention to when using stage audio. Otherwise, the sudden failure of the audio during the event is really disappointing. When it comes to this, the editor thinks that the opinions expressed by JSL audio equipment manufacturers are very worthy of our reference and warning. Here, I will summarize the maintenance and use of audio equipment by Guangdong stage equipment manufacturers. Some of the views of the method are summarized below.

　　1. The audio equipment should not be exposed to direct sunlight, and also avoid getting close to heat sources, such as heaters.

　　2. Before turning on and off the audio power supply, turn the volume potentiometer of the power amplifier to the minimum. This is the most ineffective protection method for the power amplifier and speakers. At this time, the power amplification of the power amplifier is almost zero, at most, it will also be used when there is a misunderstanding and monopoly. Will not cause harm to the speakers.

　　3. The abnormal working temperature of stage machinery and audio equipment will affect his work. The normal temperature should be between 18 degrees Celsius and 45 degrees Celsius. If the temperature is too low, it will reduce the sanity of some machines. If the temperature is too high, it will easily burn under-safe components, which may cause premature aging of components. In summer, special attention should be paid to cooling down and maintaining a smooth atmosphere.

　　4. After the audio equipment is used up, the function keys should be reset. If the function key is reset for a long time, and its pulling button spring is always in a stressed state, it is easy to cause abnormal performance.

　　5. Stage machinery should be used frequently. Common use can prolong the life of the machine, such as some parts with motors, if they do not migrate for a long time, some parts will be deformed.
