PICO - C3187 Transformer, Audio.
Audio transformers are low-power signal devices optimized for transmission of wide-frequency AC signals with very low distortion. The transformer has no direct connection between the primary and secondary windings, the electrical energy transferred using electromagnetic induction. Due to this isolated property between primary and secondary, the transformer provides electrical isolations between primary and secondary, which means from the input and output or vice versa.
