Note 1 when using the audio: For the newly purchased speaker, we have to run it in like a new car, that is, the "burn-in" in the speaker industry. Only after sufficient running in, the speaker can play its potential. Since the "horn", an important component inside the speaker, is the key component that determines the sound quality and service life of the speaker, and the speakers are mostly composed of reinforced paper cones or bulletproof cloth, the new speakers are generally relatively stiff and require a softening process, so the speaker needs to be boiled. Better sounding and more durable. Many people find that speakers need to be boiled for a while to sound better. We agree, the only difference is that someone preaches frying at high volume. This is not right. In fact, the running-in of the speaker and the car is the same principle. Only by running in slowly will the mechanical part (the vibration part is equivalent to the mechanical part) get the best running-in. Crazy cooking is not good for the speaker at all. Circles may be deformed. Therefore, simmering slowly has the taste, otherwise it is prone to problems such as sharp, hoarse, broken and unbalanced sound. As for the specific method of burning the machine, please search for relevant knowledge on the Internet, and I will not repeat it here.

Precautions 2 when using the audio: Problems in the place of use: If any audio is turned on to Z loud, it will break the sound, so it is almost the same when the volume is turned to 8. Originally, the power of this audio is 40W, if it is normal The space within 100 square meters of the family is more than enough. If you put it in the square or use it in a large classroom, its power will inevitably be unbearable.

Precautions 3 when using the audio: Prevent sudden shocks of large signals: Generally, there are the following situations: First, because the potentiometer switch has not been turned back to Z low after the last listening, or someone else has moved the potentiometer by mistake, once the potentiometer is turned on The sound is in a high volume state, causing a large signal impact. Second, there are sudden large dynamic fragments in the music. In order to emphasize the contrast, these clips are mostly weak before the big dynamic. At this time, if there is no mental preparation, turn up the volume, and the large dynamic signal will easily damage the speaker. Such as explosions, drums, thunder, etc. The third situation is that when the audio is working normally, the signal line and power line are suddenly inserted and inserted, which will cause a large current impact, which is easy to damage the speaker.

Note 4 when using the audio: usually pay attention to standardized operation: when listening to the audio, check whether the wiring is correct and whether the potentiometer position is too large. When starting, shutting down, restarting, etc., the volume of the speaker should be turned down to the minimum or the power supply should be turned off to prevent damage to the speaker caused by large inrush currents. When singing karaoke, try to stay away from the speaker, and do not point the microphone to the speaker to avoid howling or even burning the tweeter. At the same time, in order to protect the speaker, in general applications, the volume of the speaker should not be turned too high, as long as it is enough, about 1/2 is enough, because in addition to the sound distortion problem, some large dynamic fever discs are definitely speaker killers. Active speakers on the market, although the nominal power is very large (even exaggerated to hundreds of W), but that is not the actual power, generally tens of W is large. Therefore, when using it, do not work at high volume for a long time, otherwise it will easily damage the power supply and amplifier circuit. The bookshelf speaker should prevent accidental collision and fall from the tripod. It is best to stick a few pieces of double-sided tape on the bottom of the box. When the speaker has been used for a period of time, the terminals of the speaker wire will be oxidized more or less. This oxide film will greatly affect the contact state, thereby reducing the sound quality. The user should clean the contact point with detergent to maintain the best connection state. .

Precautions when using audio: Avoid using it in harsh environments: various parts of the speaker such as veneer, paper cones, high-pitched silk membranes, suspension edges, centering brackets, adhesives, voice coils, etc. Most are sensitive to changes in temperature and humidity. If the temperature is too low or too high, the stability of these components will be affected. If the temperature is too low and less than 5 degrees Celsius, the hanging edge will become brittle easily. At this time, if the volume is turned on, the hanging edge will easily break. If the temperature is too high above 40 degrees Celsius, the voice coil will be overheated, which will cause sound deterioration. Therefore, the speakers should be avoided in places with sunlight, next to radiators and places with sub-zero temperatures. The influence of humidity is also great. If it is too dry, the veneer outside the speaker will burst, and the thick wooden cabinet will be prone to cracks. The solution is to purchase a humidifier or put a basin of clean water indoors. If the humidity is too high, the sound cone is prone to damp and moldy, the sound is weak, and the wiring is easily oxidized. The solution is to put some dehumidifiers and desiccants indoors. In addition, the dustproof and cleaning of the speaker is also very important. When not listening to the speaker, it is best to add a dust cover. To clean the surface of the speaker, you can use a towel dipped in warm water to wring it out and wipe it, but you must remember to wait until the water is completely dry before turning it on. .
