Impedance Matching of Audio Components
http://hyperphysics.phy-astr.gsu.edu/hbase/Audio/imped.html
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 …
What is Impedance in Audio? Input and Output …
https://virtuosocentral.com/what-is-impedance-in-audio/
Impedance matching in audio equipment means that the output impedance from one device must be the same as the input impedance of the device that is connecting to. This ensures a good signal transfer between devices. Think of kids on a playground. When everybody gets along, things run smoothly.
How important is impedance matching in audio applications ...

Show activity on this post. Impedance matching is not used in modern audio electronics. A mic output might be around 600 Ω, while mic preamp inputs are 1 kΩ or more. A line output will be something like 100 Ω, while a line input is more like 10 kΩ. A loudspeaker amplifier will be less than 0.5 Ω, while loudspeakers are more like 4 Ω.

All connections are on the rear panel. The eight RCA unbalanced inputs have an impedance of 10kΩ and are routed to eight balanced XLR-3 outputs with an output impedance of <50Ω.The output gain can be individually adjusted for left and right channels by using pre-set potentiometers accessible through the rear panel. Specifications:...

to match the source and the receptor as indicated in the fig. 1 : Source 2 or 3 wires line Receptor (CD, tuner) (preamp) Z o Z i Fig. 1 With : Z i / Z o ≥ 10 (1) Most hi-fi gear is based upon this impedance scheme : Low output impedance, high input impedance.
Headphone Impedance Matching - Why It's Important? - …

The audio source is also made up of electronics and has an impedance value. Generally, the audio source impedance is quite low. The impedance of your mobile’s audio output measures 5 Ohms or lesser. If you’re using a headphone amplifier, you’ll get an output impedance between 50 Ohm to 100 Ohms, depending on the type of electronic components.
Is impedance matching important? : Empirical Audio
https://www.empiricalaudio.com/computer-audio/audio-faqs/should-i-match-impedances
There is no specific impedance matching between power amps, speaker cables and loudspeakers, particularly since loudspeakers represent such complex loads. The most important attributes for loudspeaker connections are: Low driver output impedance (.1-.3 ohms is good) Low speaker cable resistance and inductance
Mix and match impedance – PS Audio

Here’s a bizarre fact, the maximum power is transferred from the source to the load occurs when the input and output impedance are an exact match. But in audio that is generally not the goal. Instead the goal is to get the signal at the output of one component to match the signal at the other component with as little distortion as possible. If the output …

In audio, it does not necessarily mean driving a 47K output into a 47K input and therefore matching the two up. It can mean "matching" an output impedance of one value or range, to an input impedance of a completely different value or range (this is also done in telephone circuits with a line-matching transformer).
