Transformers - When to use and how does it work?
https://service.shure.com/s/article/transformers-when-to-use-and-how-does-it-work?language=en_US
Audio Transformers. Audio transformers can: 1) Step up (increase) or step down (decrease) a signal voltage; 2) Increase or decrease the impedance of a circuit; 3) Convert a circuit from unbalanced to balanced and vice versa; 4) Block DC current in a circuit while allowing AC current to flow; 5) Electrically isolate one audio device from another. While transformers are useful in …
What is Frequency Response?
https://edcorusa.com/blogs/hi-tek-gadgeteer-notes/what-is-frequency-response
The core of an audio transformer is a major factor in the saturation of a transformer. They core size and material effects the low end frequency. The winding of a transformer has a lot of effect to the high end frequency. The more coupling of the primary and secondary the more high frequency will pass through a transformer.
