Audio Transformers for Impedance Matching
https://islproducts.com/design-note/audio-transformers-for-impedance-matching/
With RF Antenna’s, impedance transformers are used to match an unbalanced impedance with a balanced impedance. They are commonly known as balun transformers. Audio transformers offer a wider frequency response and a known primary/secondary impedance compared to a typical power transformer allowing impedance transformers to obtain high levels of signal …

Provides 15, 20 or 25 dB attenuation. A15BT - Bridging Transformer matches balanced or unbalanced devices of different impedances.(33 kilohm primary, 600 or 7,500M ohm secondary). A15HP - High Pass Filter provides a low frequency cutoff to reduce unwanted low-frequency noise in mic signals. A15LA...
Audio Transformer - The Amazing World of Electronics
https://elamazing.com/2021/05/14/audio-transformer/
We have seen in this tutorial about audio transformers, that audio transformers are used to match impedances between different audio devices, for example, between an amplifier and speaker as a line driver, or between a microphone and amplifier for impedance matching. Unlike power transformers which operate at low frequencies such as 50 or 60Hz, …

Maintains high frequency response; Reduces noise pickup; The Audio-Technica CP8201 Microphone Impedance Matching Transformer is designed to connect a low-impedance microphone to a high-impedance electronic input. The high-quality transformer solves the problem of excessive high-frequency loss and hum pickup. Specifications
Impedance Matching of Audio Components

Impedance Matching. In the early days of high fidelity music systems, it was crucial to pay attention to the impedance matching of devices since loudspeakers were driven by output transformers and the input power of microphones to preamps was something that had to be optimized. The integrated solid state circuits of modern amplifiers have largely removed that …

Today, i series-ed the sub to make 4 ohm, and bridged the NAD. I then used a 240V/110V 200VA transformer to connect the sub to the bridged amp. 110V side to sub, 240V side to amp. By my calculations, 240/110 = 2.182. Giving a impedance multiplication of 4.76. This presents a 19ohm load to the bridged NAD.
