About the signal line Signal lines are used to transmit weak small signals, and small signals are more susceptible to interference. A normal signal line is required to have a shield. It is best to test the signal lines as good as possible. Even with very good signal lines, you will still be disturbed when using your mobile phone as a signal source. About the signal source The most commonly used signal sources are mobile phones and computers. The quality of audio signals output by mobile phones and computers according to different brand models is also different. Generally speaking, if the quality of the sound signal directly from the computer motherboard is relatively poor, it cannot be heard at a small volume, but it will be obvious after the amplifier is amplified. If you are not satisfied with the sound quality of the computer itself, you can purchase a USB decoder (equivalent to an external USB sound card) from the store to improve the sound source and greatly reduce the noise. The method of judging the source of noise is relatively simple. Do not insert the input signal into it, turn the amplifier volume up, and listen to the noise in the speaker. If there is no noise, the noise comes from the source or signal line. Precautions for use: 1 Do not use cheap audio signal lines These lines are not shielded by themselves. High-frequency noise will be introduced. The louder the potentiometer rotates, the larger the noise will become, and the sound is very good, such as Akihabara. Quiet as deep sea, no whistling 2 The correct order of use is to connect the power supply of the notebook power supply and the power amplifier first, and then let the notebook power supply be connected to the mains. The wrong way is to first connect the laptop power to the mains and then connect the laptop plug to the digital amplifier. Because the digital function has a filter capacitor inside, these will produce a slight low-voltage spark for 0.1 second, although there is no impact on performance, but this way The habit is not good either. 3 Use a power supply with as much current as possible. If you only use 2-3A power supply, the output performance will be greatly limited. Tip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please pay attention!
