Transformers for Audio Applications

Audio transformers can used to step up or step down a signal voltage, increase or decrease the impedance of a circuit, convert a circuit from unbalanced to balanced and vice versa, block DC current in a circuit while allowing AC current to flow, or electrically isolate one audio device from another.
