How Does The Audio Signal Line Work?

There are two different types of audio signal lines in terms of the nature of the transmitted signal. The first is called Interconnect Universal, and you can use it to connect multiple playback devices. For example, a CD player, or a radio and so on. The second type is called speaker amplification, and this type of signal line is used to connect the power amplifier. You need to be able to clearly distinguish between these two types of audio signal cables, and use the corresponding cables in different places. Although the audio signal transmitted between them is similar, the energy of the transmitted signal is different.
