Audio transformers can also be used for matching microphones to amplifier inputs. The main purpose of a transformer at the amplifier input is matching impedance between microphones, connecting cables and the amplifier input. This is important to ensure that there is no signal reduction due to impedance mismatching.

Air Audio goes to some lengths to emphasize that balanced mains transformers are used extensively in recording, radio and TV transmission studios and environments to lower the noise floor. Among the key benefits of these residential units are the removal of RF pick up from power cords, elimination of AC/DC ‘noise’, reduced interference between audio and AV …

An audio transformer is an electromagnetic device that is intended to isolate an input circuit from an output circuit and provide filtering to a signal that passes through it. It is an audio device because it is designed to operate on signals with a frequency spectrum in the audible band of frequencies (typically around 20Hz-20kHz). How Audio Transformers Work

The inductance of a mains transformer is not a fixed value, and I've used an estimation based on measurements (and experience). After the asymmetrical (R ext and D ext ) load has done its job, a simulation shows the positive peaks of the 240V AC waveform reach 338.35V, but the (unloaded) negative peaks reach the proper value of 339.28V.

All mains transformers generate some audible noise as a result of the alternating magnetic flux and the consequent mutual magnetic repulsion effects within their core and windings, and this can, sometimes, be annoying.
