1. The normal working temperature of audio equipment should be 18 ℃~45 ℃. Too low temperature will reduce the sensitivity of some equipment (such as electronic tube machine); If it is too high, it is easy to burn the components or make the components aging early. In summer, pay special attention to cooling and maintaining air circulation.
2. Sound 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 does not reset for a long time, its pull button spring will be in a stress state for a long time, which is easy to cause functional disorder.
4. Before switching on the audio power, turn the volume potentiometer of the power amplifier to the minimum, which is the most effective protection method for the power amplifier and speaker. At this time, the power amplification of the power amplifier is almost zero, at least in case of misoperation, it will not cause harm to the speaker. It is better to turn off the power amplifier when plugging in and out the cable.
5. Turn on the CD player from the front to the rear, then turn on the front and rear stages, and turn the volume potentiometer of the power amplifier to the minimum when starting up. Turn off the power amplifier first to turn off the amplification function of the power amplifier completely. When you turn off the front-end equipment at this time, no matter how large the impact current generated, the power amplifier and the speaker will not be affected. Also, turn the volume potentiometer of the power amplifier to the minimum when turning off, and turn it off or off before turning it off again.
