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.in addition, the left and right speakers can also be used when the subwoofer is not connected
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.
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.
