Audio signals can be analog or digital, and the transmission method can be wired or wireless. The printed circuit board (PCBA) is the circuit board used to process and transmit audio signals within audio equipment. The PCBA is a core component of audio equipment, responsible for receiving audio signals, processing them (such as amplification, equalization, and mixing), and outputting the processed audio signals to the speakers. The design and manufacturing quality of the PCBA directly impacts the sound quality and performance of the audio equipment.

[0003] In audio equipment, the main function of the audio transmission PCBA board is to receive, amplify and process audio signals and transmit them to the speakers for playback.
