In this article, I want to talk about transformers; their practical applications, and their seemingly magical effect on audio signals.
Transformers, nondescript, but important electronic components, are ubiquitous in professional audio gear, both in the power supply and in the audio path. Audio transformers are used in analog consoles, DAW interfaces, most every piece of outboard gear, many microphones, powered monitor loudspeakers, and power amplifiers used for monitor speakers and headphones systems. Here, we will focus on the audio applications of transformers and only lightly touch the power supply uses.
A well-known use of audio transformers is inside a DI or “direct injection” box where a low-level and high impedance unbalanced signal from a guitar or bass is balanced, impedance-matched, and buffered by the DI’s transformer to interface well with a microphone pre-amp. As another example, the Shure SM-57 contains a miniature transformer that balances and matches its capsule’s output to a microphone pre-amp.
