Daily maintenance of audio

　　Audio is the treasure of music lovers. It needs maintenance and care during daily use. If it is not properly maintained, the service life of the audio may be greatly shortened. So how to maintain the sound?

　　Attention should be paid to the new machine test machine

　　Many friends who bought a new stereo are usually very excited to plug in the power immediately and try the effect. But you must pay attention, do not directly test the machine when the audio is not connected to the power amplifier, it will directly impact the circuit of the power amplifier. The gains may outweigh the losses, so we must check whether all the devices are connected when testing the machine, and make sure that the volume is turned to the minimum before starting. , to avoid affecting hardware performance.

　　use under reasonable conditions

　　Generally speaking, the ambient temperature should be controlled at least between -10°C and 40°C, and the temperature environment should try to avoid large fluctuations. Excessive temperature changes and the use of audio in extremely low and extremely high environments will cause irreversible damage to the audio system. In terms of humidity, speakers should be placed between 50% and 80% relative humidity. An environment that is too humid can cause premature failure of components inside the machine, or rust inside and outside the machine. In addition, the power supply voltage and frequency need to be consistent with the local power supply. If the speaker works under non-rated voltage and frequency power conditions for a long time, it will also accelerate the aging of the speaker.

　　Avoid direct sunlight and stress

　　In terms of placement space conditions, speakers must first avoid dusty environments and vibration environments. Excessive dust will not only close the heat dissipation holes to prevent heat dissipation, but also cause damage to specific circuits after entering the inside of the body. In addition, whether the audio is a power amplifier or a speaker, there must be enough space around, especially on the power amplifier, do not stack other equipment.

　　Device switching sequence

　　Like the computer, the audio system has the same problem of switching on and off the device. We must pay special attention to the sequence of power on and off. Remember to turn the volume down to the minimum when powering off, so as to avoid scaring yourself the next time you turn it on.
