The typical broadcast-quality analog audio cable has a characteristic impedance of 45 Ohms. ALMOST LIKE DC Audio cable with XLR connectors for analog use can look identical to a cable for digital use, but an analog cable can kill a digital feed. In the analog world, audio is relatively low frequency and it behaves almost like DC.

That's why the characteristic impedance of audio interconnect cables is not something most of us have anything to worry about. Normal video signal rarely exceed 10 MHz. That's about 20 meters for a wavelength. Those frequencies are getting close to being high enough for the characteristic impedance to be a factor.

The common 'zip cord' used as audio speaker cables may have impedance around 100R. As an example consider a line with characteristic impedance 100R. is used to connect an 8 ohm load to an amplifier with 0.1 ohm output resistance, there will be reflection of energy back from the load, and energy will be reflected back and

Since cable lengths between towns were comparable to the wavelength of the audio signals carried, it was important that the impedances of the sending and receiving telephone exchange equipment, along with the characteristic impedance of the cables (see 'Characteristic Impedance' box), were properly matched.

Impedance When Connecting Audio Devices Such as Mixers and Microphones. When electric current travels through a conductor from one device to another, you would want to have a higher impedance at the input and a low impedance at the output. For instance, if you connect a microphone to a mixer, your microphone has an impedance of less than 200 Ohms.
