32-bit voice-activated music level light quick question and answer: Q: Where can I use it? Is the wiring complicated?
A: It can be used as long as there is an external sound. Because this product uses a silicon microphone to collect signals, it only needs to plug in a 5V / 150MA power source and it can work normally just like charging a mobile phone.
Q: What is the difference between this model and the level light connected to the audio signal line?
A: The level light connected to the signal line is a direct input signal to the light board for processing, so the audio details and rhythm performance is very good, but the input signal has requirements, and only professional personnel can install and use it correctly. There is no way for ordinary consumers to use it. Because the microphone level light uses the microphone to collect signals, it is definitely impossible to achieve the level of the wiring signal level light due to the influence of the audio playback equipment, the playback environment and the microphone itself. The advantage is that this product is very convenient to use, the aluminum alloy housing, Small and exquisite appearance, when you use it just like charging a mobile phone, it can work normally when connected to the power supply.
Q: Why does the rhythm of the light board feel bad when the device such as mobile phone laptop is placed outside?
A: As mentioned earlier, it has something to do with the playback equipment. The external amplifier of a mobile phone or a laptop does not even sound like the rhythm of a large speaker. Why do you want the light board to have a rhythm? This is a matter of common sense.
Q: Why is there still a wrong rhythm when playing music with a large speaker?
A: It's still mentioned earlier, it's related to the playback equipment and playback environment. The signal collected by the microphone is only related to the loudness of the sound, which is the size of the sound we often say. Generally, the main part that gives us a sense of rhythm is the low-frequency part. If at this time there is a human voice singing at the middle frequency, and the loudness and the low-frequency loudness are comparable or even louder, the microphone will naturally collect the highest loudness of the human voice Processing, so that there is a phenomenon that does not correspond to the sense of rhythm. In addition, the playback environment will cause resonance in certain frequency bands of the audio. For example, low frequency is most likely to resonate with the environment. When resonance occurs, people may not feel it, but the light board will show that the light bar is continuously at the top. It is also normal.
Q: Is there anything else I should pay attention to when using it?
A: Yes, all products need to pay attention to how to use it.
1. Do not use excessive force when plugging or unplugging the power cord to prevent the internal adhesive from cracking.
2. Be careful not to drop or drop, so as not to damage the internal microphone.
3. Do not block the microphone collection hole or blow inward.
4. Although the light board has a very wide AGC range, if the sound is too small, it will not display properly. At this time, please slightly increase the music or place the light board near the speaker or speaker.
5: Multiple light boards are used at the same time. Due to the entire AGC tracking process, the display amplitude of each light board will definitely not be the same. The AGC function cannot be turned off. If you have any objections to this, please do not purchase it.
