Audio TransformersAudio transformers are electronic components that are used to convert AC signals from one level to another. They are commonly used in audio equipment, such as amplifiers and microphones, to match the impedance of different devices and to provide electrical isolation between circuits. Audio transformers are typically designed to operate at audio frequencies, which are generally in the range of 20 Hz to 20 kHz. They can be used to convert signals between high and low levels, or to transform a balanced signal into an unbalanced signal, or vice versa. Audio transformers are available in a variety of sizes and shapes, and they can be designed for specific applications or for general-purpose use.
