What is "Impedance Balancing"?
https://www.sweetwater.com/insync/impedance-balancing/
This is not a truly balanced system, but in terms of noise cancellation behaves similarly. If you are working with a device that employs impedance balancing you should connect it to other balanced devices just as if it’s a normal …

Impedance-balanced Send: Increasingly, manufacturers are using impedance-balanced outputs. The signal is still being transmitted differentially, but only the hot wire carries the (full level) signal. The cold wire is arranged to have the same impedance to …
What is Impedance in Audio? Input and Output …

For instance, if you connect a microphone to a mixer, your microphone has an impedance of less than 200 Ohms. The input impedance of the XLR balanced connector of a mixer or preamp is between 1500 – 3000 Ohms. This ensures an excellent current flow between the two devices.

From the balanced input’s standpoint, there are equal impedances from both sides of the line to ground. This results in the best CMR performance, especially if close-tolerance resistors are used at the output side. From an induced noise standpoint (the kind of noise that a balanced input is supposed to reject) this is what counts.

Electrical, or impedance balanced, allows the rejection of external noise by ensuring any electrical interference is induced equally in hot and cold signal legs. This allows the common mode rejection characteristics of a balanced input stage to reject these common mode signals and hence maintain the audio fidelity of the signal. To achieve this balanced line …

- An audio transformer is a classic way to convert unbalanced to balanced - Balanced opamp output circuit can convert unbalanced to balanced (more modern approach but more components) In addition to those there is not so widely mentioned impedance-balanced output option: 1. Figure out the output impedance of your unbalanced signal source.
Understanding Impedance - Sound on Sound
https://www.soundonsound.com/techniques/understanding-impedance
In audio input and output circuits the impedances are principally resistive to make interconnection easier — the impedance won't change too much over the range of audio frequencies. However, the impedance to radio frequency (RF) signals will often be very different to that at audio frequencies in order to keep RF interference out.
