Audio Transformers

Audio transformers are electronic components used in audio systems to provide signal isolation, impedance matching, and voltage level adjustment. They convert audio signals from one impedance level to another, allowing for efficient transmission and reception of audio signals. Audio transformers use electromagnetic induction to transfer the audio signal from one circuit to another, and they consist of two or more coils of wire wound around a magnetic core.

Audio transformers provide electrical isolation between input and output circuits, eliminate ground loop hum and other interference, match the impedance of input and output circuits, and adjust the voltage level of the audio signal. They have a frequency response that matches the frequency range of the audio signal, ensuring accurate and clear reproduction of sound. Audio transformers are used in recording studios, broadcast systems, musical instrument amplifiers, and telecommunication systems.
