Scientific maintenance of audio equipment, is to extend the life of the key. Here are some basic common sense of routine maintenance:
1, the normal working temperature of audio equipment should be 18 ℃ ~ 45 ℃. Too low temperature will reduce the sensitivity of some machines; too high is easy to burn components, or premature aging of components.
2, audio equipment, avoid direct sunlight, but also to avoid close to heat, such as heaters.
3, 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.
4, switch the sound power before the power amplifier to the minimum volume of electricity **, which is the amplifier and speaker of one of the most effective means of protection.
5, boot from the front open to the post, that is, the first to open the CD machine, and then open the pre-and post-level, power amplifier when the volume of the power switch to the minimum **. 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.
6, the machine should be used, if not long-term rotation, some parts will be deformed.
7, to regular power. In the case of long-term use is not particularly in the wet, hot season, the best half-hour power every day. 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.
8, from time to time with a clean soft cotton cloth to wipe the machine surface; when not in use, dust cover or cover cloth to cover the machine to prevent dust into the inside.
9, do not open the amplifier to pick up speaker cable, because the distance between the speakers are generally close, the speaker line is tightly parallel to the two, the wiring is often not careful to short-circuit speaker cable, the consequences will be rapid Burned amplifier.
