What is Impedance in Audio? Input and Output …

In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance measurements, namely input, and output impedances. More on that later.
Output impedance - PS Audio

Output impedance refers to a device’s ability to deliver unrestricted current or power when passing a musical signal – it measures the amount of restriction or hold back of that signal. It is important to understand output impedance only as it is relative to the input impedance of whatever the amp is driving.

Usually, the component’s impedance changes as the electrical signal’s frequency changes. As for output impedance, this is how much impedance there is between an output device of an amplifier or preamp and the component’s output terminals. It also includes the device’s internal impedance as well. But why do devices need output 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.

Because the impedance (alternating current resistance) of speakers and headphones is frequency dependant, it's not advisable to achieve impedance (and power) matching. While the output impedance of phones, MP3 players etc. is usually in the range of several ohms, the impedance of headphones goes usualy from 20 to several 100 ohms.
Line Out vs Speaker Out: What's the Difference? (Explained!)

Output Impedance Impedance, which is measured in ohms, is the measure of the resistance to alternating current presented by an object. When your equipment or audio device outputs audio signals, we can say it has an output impedance. Line outputs have an …
