audio-frequency transformers Audio-frequency (af) transformers are used in af circuits as coupling devices. Audio- frequency transformers are designed to operate at frequencies in the audio frequency spectrum (generally considered to …
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
The audio transformer works at frequencies between 20 Hz to 20 kHz. So, the operation of an Audio transformer has much wider frequency range. As discussed above, the audio transformer uses Impedance balancing technique. It is very useful for balancing amplifiers and loads (Loudspeaker and other) that use a different input or output impedances for …
Power Transformers for Audio Equipment | audioXpress

Power Transformers for Audio Equipment. In this article, author Pete Millett explores the different types of power transformers, and why you might choose to use each type in audio equipment. The article addresses issues with low-frequency (50–60Hz) line transformers, but many of the same issues apply to audio-frequency transformers as well. Newcomers to the …

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.
Audio Transformers - Learn About Electronics
https://www.learnabout-electronics.org/ac_theory/transformers04.php
Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output transformers.
6moons audio reviews: Trafomatic Experience One

The power supply is 230/115V, 50/60Hz but should be changed only by an experienced technician because it'll require rewiring the amplifier. Input sensitivity is 1Vrms, power output 2 x 4 watts into 4/8 ohms. Frequency response is 10Hz - 35kHz (-3dB), S/N at 1-watt output 64dB.

Even the design of a relatively simple 60 Hz power transformer must take them into account. The design of an audio transformer operating over a 20 Hz to 20 kHz frequency range is much more difficult because these elements often interact in complex ways.
K&K Audio Premium MC Phono Step-Up Transformer Review ...

It transforms, anywhere between 550 and 2500 volts down to the relatively safe 120 and 240 volts used inside. An MC SUT is used the other way around. The SUT takes the approximately 0.5 mV and steps it up to around the 5mV that the phono stage is expecting. There’s no free lunch for this transformation .
