In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

A critical device that helps in creating this blend is an audio transformer. Works just like any other conventional transformer; audio transformers are designed to work at audio frequencies, i.e. between 20Hz to 20 KHz. Interestingly, the initial need to design to such transformer was to enhance long distancevoice communication.

Stricly speaking you should use an audio transformer to couple the earpiece signal into the sound card, this provides DC isolation and some protection against lightning. Adding a TVS across the output of that transformer would be a good idea too. The ac signal on the earpiece might be quite small. Only a few hundred mV.
Audio Transformer, its Types and Impedance Ratio

An Audio transformer with Step-up feature will step up the voltage or the current level to drive a load across it. Same happens for the Stepdown transformer too. It converts the voltage from higher to lower with the increased current output. The audio transformer also provides impedance matching specifications. When the output of one circuit or device is …
