【 Weak current College 】 audio equipment maintenance of basic common sense---Power By 【 China power house network 】

1. audio equipment normal working temperature should be 18 ° c ~ 45 ℃. The temperature is too low will reduce some machines (such as electron tube machine) sensitivity; too high you can easily burn component, or the components of early aging. Summer special attention should be paid to maintain cooling and air flow.

2, audio equipment, be sure to avoid direct sunlight or near heat sources to be avoided, such as the heater.

3. audio equipment after use, the function key you want to reset. If the function key for a long stretch the button Reset, its long period of time in the spring of stress, it is easy to cause functional disorders.

4. switch audio power supplies, power amplifier's volume potentiometer screw to the minimum, this is a power amplifier and speakers in one of the most effective means of protection. This time the amplifier's power zoom in almost to zero when at least mistaken operation would cause harm to the speaker.

5. power-on time by the former to back, first open the CD, and then open the fore and after the class, the power amplifier's volume potentiometer screw to a minimum. Shuts off the amplifier, first let power amplifier amplified shutdown cleanly, you then turn off the front-end device, whether produced another big shock current nor plants and power amplifier and speakers. Similarly off-face when power amplifier's volume potentiometer screw is adopted to off or on and off before and CD player.

6. the machine has to commonly used. Commonly used but can extend the life of the machine, such as some part of the belt motor body (audio seats, CD player, VCD player, etc.). If not, some long parts also deformation.

7, to regular power. In the long term not used especially in damp, high season, the best power up half an hour every day. This way you can take advantage of built-in components of heat generated when working to drive out moisture and avoid internal coil, speaker voice coil, transformer moisture and mould.

8, every time you want to use a clean, damp cotton cloth, wipe the surface with soft machine; when not in use, the application of dust cover or cover cloth machine cover, preventing dust.

9, the principle from the electronics, any electronic device in the live working status should not connect or disconnect the other device, which I want to do too many instructions friends can understand, live-plug active device is a very dangerous, and even microphones such passive device nor advocate Live-plug. Necessary to remind that don't open power amplifier to the speaker cable, because the distance from the speaker Terminal is generally very close to the speaker cables are two closely parallel wiring is often, carelessly loudspeaker line short circuit, the consequences will be promptly Burns power amplifier. In spite of the amplifier is equipped with protection circuits, but some of the pure Hi-Fi amplifier in order to improve quality, reduce unnecessary bass, tend to save this part of the protection measures. Therefore the "shutdown and then wiring" this sentence had already become enthusiasts must comply with the rule.

10, some stress some of enthusiasts in the amplifier heat is not button large volume and play some music of bursting, truth is power amplifier components just post in the cold state, then let their current work will shorten its life. Thus some enthusiasts in the just-on-a-half hours only play some soft music and listen to music with medium volume, standby, warm-up and turn up the volume and enjoy.
