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 …

ern audio products and the optimal noise performance is attained when the characteristic “noise resistance” of the amplifier, Rn, is equal to the source resistance, Rs. While transformers are not required, as in tube circuits, a precision input transformer will optimize the op-amp to the source impedance, which is unequal to the op-amp’s Rn.

Audio transformers should preferably use both high-permeability cores and the largest number of coil turns to create high primary inductance. The most commonly used audio transformer core materials are M6 steel (a steel alloy containing 6% silicon) and 49% nickel or 84% nickel (alloys containing 49% or 84% nickel plus iron and molybdenum).

The Audio-Technica CP8201 is an in-line low to high impedance barrel adapter for connecting microphones to 1/4" phone line-level inputs. The barrel adapter features XLR input and 1/4" phone output connectors. Matches low-impedance microphones to high-impedance electronic inputs. Permits use of long microphone cables.
201A Audio Transformer Impedance - Antique Radio Forums
https://antiqueradios.com/forums/viewtopic.php?t=379823
It is unusual to find such a high primary impedance audio transformer. Best you can find new is the Hammond 125ASE with a 10K primary and use the 4 ohm tap with an 8 ohm speaker to have 20K reflected impedance back to the primary winding. I am using 5K primary now and will try 8 ohm and 3.2 ohm speakers on new transformer.
Osborne Transformer's High Impedance Transformers
https://osbornetransformer.com/products/transformers/high-impedance-transformers/
High Impedance Transformers. Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a …
