First, the use environment. Try not to place it in direct sunlight, and do not place heavy objects on the top of the Bluetooth speaker to avoid deformation of the casing. In addition, pay attention to the ambient temperature of portable Bluetooth speakers. The normal ambient temperature of general audio equipment should be 18°C to 45°C. If the temperature is too low, the sensitivity of some components such as electronic tube machines will be reduced.
Second, is to start and shut down. Some split portable Bluetooth speakers should turn on the main audio source such as the CD player first, and then turn on the audio unit; when shutting down, turn off the audio unit first, and then turn off the main audio source. When turning on the power amplifier, the volume switch of the power amplifier should also be turned to the minimum to avoid damage to the sound by the instantaneous loud volume.
Third, is the volume adjustment. When using a portable Bluetooth speaker to enjoy music, it is necessary to avoid turning the volume of the speaker to the maximum. Damaged components, which in the long run can cause some of the fragile internal sound components to fail.
