Fever audio equipment maintenance dry goods

　　1. The normal working temperature of audio equipment should be 18℃～45℃. If the temperature is too low, the sensitivity of some equipment (such as tube machines) will be reduced; In summer, special attention should be paid to cooling down and maintaining air circulation.

　　2. Audio equipment should not be exposed to direct sunlight, and should also be kept away from heat sources, such as heating.

　　3. After the audio equipment is used up, the function keys should be reset. If the function key is not reset for a long time, its pulling button spring will be under force for a long time, which will easily cause malfunction.

　　4. Before turning on and off the audio power supply, turn the volume potentiometer of the power amplifier to the minimum, which is the most effective means of protection for the power amplifier and speakers. At this time, the power amplification of the power amplifier is almost zero, and at least it will not cause harm to the speaker when it is misused.

　　5. Turn on from front to back when starting up, that is, turn on the CD player first, then turn on the front and rear stages, and 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 amplification function of the power amplifier is completely turned off. At this time, when you turn off the front-end equipment, no matter how large the inrush current is, the power amplifier and speakers will not be affected. Also, turn the volume potentiometer of the power amplifier to the minimum when it is turned off, and it can be connected to the CD player before turning it off or after turning it off.
