1, new machine test machine to be careful

Many people just bought a domestic Bluetooth speaker and want to plug it in. Be sure to pay attention to whether the speaker is connected to the amplifier, and try to see if there is a chance to directly affect the amplifier circuit. Audio is a passive device, and all the energy comes from the output of the power amplifier. Therefore, be sure to check the startup of all connected devices, make sure the volume knob is turned down to very small, and then start the system.

2, try to use under reasonable ambient temperature

The temperature of the environment in which the domestic Bluetooth speaker can be used should be controlled at least between -10°C and 40°C, and the temperature control environment can avoid large fluctuations as much as possible. Excessive temperature changes and the use of audio in very low and high social environments will cause irreversible damage to the development of audio equipment systems.

3, pay attention to environmental humidity

In the case of high environmental humidity, the relative humidity of the domestic Bluetooth speaker should be between 50% and 80%. Too humid environment will make the machine parts premature failure, or inside and outside the body rust.

4. Pay attention to voltage frequency

The voltage and frequency of the power supply shall be consistent with the local electricity. Operating the sound for a long time under non-rated voltage and frequency power conditions will accelerate the aging of the sound.

Avoid excessive dust environment and excessive vibration

In addition to the well-known avoidance of direct sunlight and heavy pressure, domestic Bluetooth speakers must first avoid dusty environments and vibration environments when placing spaces. In audio systems, especially power amplifiers are very sensitive to ambient dust. Because of the need for heat dissipation, each power amplifier will have heat dissipation holes. Excessive dust will not only close the heat dissipation holes, but also cause damage to specific circuits after entering the body. In addition, whether it is a power amplifier or a speaker, there must be enough space around, especially not to pile other equipment on the power amplifier.

6. Pay attention to equipment switching sequence

The Bluetooth speaker of domestic mobile phone has the same problem as computer technology, and there is also the problem of the time sequence of switching on and off some equipment. When using a sound, the signal source equipment should be started first. In addition to power amplifiers, our country will also affect the selection of sound source equipment such as disk drives. In the process of starting several equipment companies one after another, our teachers should pay special attention to the startup and shutdown sequence. When starting up, the front-end equipment such as sound source such as disc drive should be started first, and then the power amplifier should be turned on. When shutting down, turn off the power amplifier first and then turn off the front-end equipment. When turning off the machine, the volume of the stereo should be adjusted to a very small level. Not only can students effectively reduce the impact on the stereo when the machine is switched on and off, but also they will not frighten yourself when turning on the machine next time.

7, pay attention to special things

Whether it is the plug behind the amplifier or its own plug, it will affect the system and damage the speaker body and speaker when using the live plug and the non-live plug.

8, clean, do not wipe with water

Wipe with water is not recommended when cleaning the stereo. The shell of audio equipment is also made of metal, and waterproof audio is relatively rare, so water will corrode the shell, and the conductivity of water is not suitable for cleaning agents.
