How to maintain professional audio equipment?

　　1. The normal operating temperature of professional audio equipment should be 18℃～45℃. Too low temperature will reduce the sensitivity of some machines (such as electronic tube machines); too high a temperature will simply burn out the components or cause the components to age in advance. Special attention should be paid to cooling down and maintaining air circulation in summer.

　　2. Do not expose professional audio equipment to direct sunlight, and prevent it from getting close to heat sources, such as heaters.

　　3. After the professional audio equipment is used up, the function keys should be reset. If the function key is not reset for a long time, and the torsion spring is under stress for a long time, it will simply cause a malfunction.

　　4. Before turning on or off the audio power, turn the volume potentiometer of the power amplifier to the minimum. This is a useful protection method for professional power amplifiers and professional speakers. At this time, the power expansion of the power amplifier is almost zero, and at least it will not cause harm to the speakers during misoperation.

　　5. Turn on the CD player from the front to the back when turning on, and then turn on the front and rear stages. Turn the volume potentiometer of the power amplifier to the minimum when turning on. When shutting down, turn off the power amplifier first, so that the expansion function of the professional power amplifier is completely closed. At this time, when you turn off the front-end equipment, no matter how large the inrush current occurs, it will not affect the professional power amplifier and professional speakers. Turn the power amplifier's volume potentiometer to the minimum when closing the surface, and turn it off or turn it off before it can interact with the CD player.

　　6. The machine should be used frequently. It is often used to extend the life of the machine, such as some parts with motors (recording decks, laser disc players, laser video disc players, etc.). If it does not rotate for a long time, some parts will be deformed.

　　7. Power on regularly. When it is not used for a long time, especially in humid and high temperature seasons, it is best to power on for half an hour a day. In this way, the heat generated during operation of the internal components can be used to drive away moisture and prevent internal coils, speaker voice coils, transformers, etc. from being damp and moldy.
