Professional audio equipment maintenance and maintenance is essential, which is directly related to the professional audio equipment life and security, so some simple audio equipment maintenance knowledge is must learn!
1, the normal working temperature of audio equipment should be 18 ℃ ~ 45 ℃. Too low temperature will reduce the sensitivity of some machines (such as electronic tube machine); too high is easy to burn components, or premature aging of components. Summer to pay special attention to cooling and maintain air circulation.
2, switch the sound power before the volume potentiometer to the amplifier to the minimum, which is the amplifier and speaker of one of the most effective means of protection. At this time the amplifier power amplification is almost zero, at least in the misuse of the speakers will not cause harm.
3, boot from the front open to the post, that is, the first to open the CD machine, and then open the front and rear level, turn the power amplifier when the volume potentiometer to the smallest spin. Turn off the first power amplifier, amplifier amplification function completely closed, this time you turn off the front-end equipment, regardless of the impact of the current will not have a big and power amplifier and speakers. Also close the amplifier when the volume potentiometer to the minimum, off or put off before the CD with the machine.
4, in the case of long-term use, especially in the wet, high temperature season, the best power every day for half an hour. This can use the heat generated by the machine components to get rid of moisture, to avoid the internal coil, speaker voice coil, transformer and other moisture mold broken.
5, audio equipment is exhausted, the function keys to be reset. If the function key is not reset for a long time, the pull button spring is in a stress state for a long time, and it is likely to cause malfunction.
6, the machine should be used. Commonly used to extend the life of the machine, such as some of the motor with the body (recording seat, CD player, laser disc player, etc.). If the long-term does not turn, some parts will be deformed.
