The speaker is an important part of the entire audio system. You need to pay attention when using it. There are some usage habits that may cause damage to the speaker. Here are a few bad habits that you don't pay attention to. I hope it can be helpful to you.
1. Frequent hard feedback: If your ears feel tingling because of the long and sharp feedback sound, it means that the speaker has also been damaged! If you continue to use the speaker after damage, it will make the situation worse.
2. It is recommended to turn the volume knob of the speaker to the lowest before turning on the speaker to play sound, and do not suddenly increase the volume knob in daily use, so that we can prevent excessive audio signals from impacting the speaker unit and damaging the speaker. "
3. Friends who use the computer should pay attention. When we are using the microphone and turn on the speaker for voice chat, we should pay attention to prevent the sound of the speaker from entering the microphone to form acoustic feedback, and then produce high-frequency howling. Such high-frequency howling can easily damage or even burn out the high-frequency unit of the speaker.
4. The number of speaker systems cannot meet the sound pressure level requirements or suitable coverage: add speakers to provide additional amplification channels instead of using higher watts on the same speaker.
5. Try to use an indoor system to meet the needs of outdoor performances. Compared with indoor performances, outdoor performances need at least 12db audio output, and at least 20db can meet their needs.
6. Excessive use of equalization: The classic smiling face equalization curve is an evil smile for speakers. Keep in mind that equalization should be used to cut audio rather than enhance the signal. Need more treble? Then reduce the bass. Need more bass, then reduce the treble.
7. Wrong use of compressor/limiter: Excessive compression and frequency limit shorten the life of audio files and compressors.
8. Insufficient amplifier space: If your amplifier has insufficient power (not enough headroom), clipping will occur, which will damage the compression driver.
9. Try not to leave the speaker unused for a long time, use it at least several times a month, and use it for at least one hour each time. Especially in the high temperature and humid season, this can make the components in the box work to drive away moisture by heating, and we can also prevent some problems such as static fatigue of materials and leakage of electrolytic capacitors.
10. Clipping before the signal reaches the active loudspeaker: This is caused by incorrect system gain structure and excessively high mixer line level output.
11. Continue to use after the loudspeaker is damaged: Continue to use the speaker without checking the crossover point after the speaker is damaged. Let your ears be your guide. If you can still hear the distortion after inputting a clear signal, it is likely that there is a problem with the speaker.
