Audio Transformer creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. The primary and secondary winding turns ratio fixed to 1:1. Due to this, the transformer does not alter the voltage or current level. It does only create isolation between the Input amplifiers with the output speaker system.

If you have the ability you can apply an AC voltage to the primary and measure the AC voltage on the secondary side. A good place to start is get the turns ratio so apply a low AC voltage like maybe 3 volts to the primary and measure the secondary. If I apply 3 volts and get out 1 volt I have a 3:1 turns ratio.

Audio transformers are designed for audio range of frequencies, i.e., for frequencies ranging from 20 Hz to 20 KHz and are used primarily in audio circuits. Fig. 1: Representational Image Showing Insides of a Typical Audio Transformer. The important functions of an audio transformer are: 1. Impedance Matching.

Audio transformers must utilize both high-permeability cores and the largest practical number of coil turns to create high primary inductance. Coil inductance increases as the square of the number of turns and in direct proportion to the permeability of the core and can be approximated using the formula: L = 3.2 N28 ì A / 10 R

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.

Transformers For Small Signal Audio. The term 'subsonic' is often used, but that implies less than the speed of sound. The correct term is infrasonic, meaning below our hearing threshold. Using a transformer in a small signal audio circuit is a simple process, and at first glance there is nothing that can go wrong.

OUTPUT AUDIO TRANSFORMER DESIGN The output transformer in a single-ended tube amplifier is the device which matches the high-output impedance of the tube to the low input impedance of the speaker load (4, 8 or 16 Ohm). To design an output transformer, it is necessary to determine the output power according to the tubess characteristics,

The connection is easy: connect primary side of the transformer to one audio connector and secondary to other. I used EOP Z1612 transformers in my test circuit and got quite acceptable frequency response of +-1 dB from 40 Hz to 20 kHz as you can see in figure below. The bass frequency below 40 Hz is not good.
