Audio Transformers - Learn About Electronics
https://www.learnabout-electronics.org/ac_theory/transformers04.php
Audio transformers often perform several functions at once: Where used, they allow the AC audio signal to reach the loudspeaker whilst preventing any DC from the amplifier affecting the operation of the loudspeaker. They provide an …

Transformers do a lot of different jobs in audio gear, including: Stepping voltages up or down: increasing output level of microphones, bringing instruments down to mic level, etc. Providing balanced inputs and outputs. Impedance matching. Eliminating ground loops. Blocking DC while passing audio signal.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
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 …
Output Transformer Impedance
https://www.radioremembered.org/outimp.htm
The function of the audio output transformer is to transform the high impedance of the output tube to match the much lower impedance of the speaker. This is necessary to get an efficient transfer of the audio signal to the speaker. The output transformer as an impedance matching device, works on the principal of reflected load.
Transformers - When to use and how does it work?

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.

In today’s world, the role of an amplifier’s output transformer (OT) is well known. As guitarists discover this critical link between your power tubes and the speakers, the important effect it has on your amplifier’s character becomes obvious. In response, an entire cottage industry has arisen to provide tweak happy guitarists with upgraded power and output “iron.”.

Grossly oversimplified, a transformer works by converting an AC current to a varying magnetic field, and then back into an AC current. Coiling wire into a “winding” and passing current through it produces the magnetic field. Conversely, the field passing through another winding induces a current in it, which is used to drive the load.
