1, the abnormal temperature of the stage sound equipment will affect his work. The normal temperature should be between 18℃ and 45℃. The temperature is too low, which will suppress the naivety of some machines. If the temperature is too high, the components will be completely burned and the components will age prematurely. In summer, we should pay special attention to cooling and keep the atmosphere unobstructed.
2. Audio equipment should avoid direct sunlight and be close to heat sources, such as heaters and heaters.
3. After the audio equipment is used, the function keys should be reset. If the function key is reset for a long time, the pull button spring is in a stressed state for a long time, and it is easy to appear abnormal group change.
4. Before turning on the audio power supply, adjust the volume potentiometer of the power amplifier to the minimum, which is one of the most ineffective protection methods for the power amplifier and speakers. At this time, the power amplification of the power amplifier is almost zero, and at most, it will not harm the speaker when misunderstood.
5. Turn on the CD player from front to back, that is, turn on the CD player first, then turn on the front stage and the back stage. When turning on the power amplifier, set the volume potentiometer to the minimum. Turn off the power amplifier before turning it off, so that the volume potentiometer of the power amplifier can be adjusted to the minimum, and then connect it to the CD player after turning it off or restarting it.
6. The stage stereo should be used frequently. Common use can actually delay the life of the time machine, such as some parts with motors, which will be deformed if they are not moved and replaced for a long time.
7. Send electricity on schedule. When not in use, especially in humid and low-temperature gas festivals, it is best to electrify for half an hour every day. How can we use the ignition heat of internal components to drive away moisture and prevent internal coils, speaker voice coils, transformers, etc. To avoid being damaged by moisture?
8. Wipe the mechanical surface with a clean and moist soft cotton cloth every other year. When not in use, cover the machine with a dust cover or cloth to prevent dust from entering.
9, from the electronics principle, any electronic equipment.
