MET Series, Audio Transformers

Audio transformers, like other types of transformers, are composed of multiple coils of wire that are magnetically coupled together. These coils are typically wound around a magnetic core. Audio transformers have specific characteristics that distinguish them from other transformer types. They are designed and optimized to operate within the frequency range that is perceptible to the human ear, which spans approximately 20 Hz to 20 kHz. The primary purpose of audio transformers is to isolate and transform analog information. They play a crucial role in various applications where audio signals need to be transmitted, processed, or converted. Unlike transformers used for digital signaling protocols, audio transformers are specifically tailored for handling analog audio signals. One common application of audio transformers is in vacuum tube amplifiers, where they serve as output transformers. These transformers are responsible for matching the high impedance of the vacuum tube amplifier to the lower impedance of the speaker, allowing for efficient power transfer and impedance matching. Another example is voice coupling transformers used in traditional telecom applications. These transformers are employed to couple and transmit voice signals in telecommunication systems, ensuring clear and reliable communication between users. In summary, audio transformers are a specialized type of transformer designed for use within the audible frequency range. They enable the isolation, transformation, and transmission of analog audio signals in various applications such as vacuum tube amplifiers and traditional telecom systems.
