The audio isolator function has two purposes. One is to prevent the current sound of the audio system and eliminate the annoying current ; the other is to change the coaxial unbalanced signal line transmission of computers and ordinary music players into balanced lines to meet the long-term requirements. distance transmission requirements. Isolators are effective tools that can convert unbalanced signals and balanced signals into each other.
