Bluetooth speaker daily maintenance tips
The normal temperature of the sound should be 18 ° C ~ 45 ° C. Too low a temperature will reduce the sensitivity of some machines (such as tube machines); too high will easily burn out components or premature components. Special attention should be paid to cooling and maintaining air circulation in the summer.
Avoid direct sunlight and avoid near heat sources such as heaters.
After the audio equipment is used up, each function key should be reset. If the function key is not reset for a long time, the pulling button spring is under stress for a long period of time, and it is easy to cause malfunction.
Before switching the audio power supply, turn the amplifier's volume potentiometer to the minimum, which is the most effective protection for the amplifier and audio. At this time, the power amplification of the power amplifier is almost zero, and at least in the case of misoperation, it will not cause harm to the sound.
When starting from the front to the back, the CD player is turned on first, then the front and rear stages are turned on, and the volume potentiometer of the power amplifier is turned to the minimum when the power is turned on. Turn off the power amplifier first, and let the amplifier's amplification function be completely turned off. At this time, when you turn off the front-end equipment, no matter the large impact current, it will not affect the amplifier and the sound. When the same level is closed, the volume potentiometer of the power amplifier should be turned to the minimum, and the CD player can be turned off or off before being turned off.
It is necessary to power on regularly. In the long-term non-use, especially in the humid, hot season, it is best to power on for half an hour every day. In this way, the heat generated by the sound can be used to remove the moisture, and the internal coil, the speaker voice coil, the transformer, etc. can be prevented from being damaged by moisture.
Wipe the sound surface with a clean, damp soft cotton cloth at regular intervals; when not in use, apply a dust cover or a cover to prevent dust from entering.
