Is impedance matching important? : Empirical Audio

If the speaker cable characteristic impedance closely matches the impedance of the loudspeaker, these resonances can be absorbed by the resistance of the speaker. In order for this to happen, however, the speaker impedance must be purely resistive and equal the cable Z 0 at high frequencies. Very few speakers have this characteristic.

cable, in order to better understand how the electrical signal travels into it. As we will see later, I wasn't able – yet – to directly correlate measurements and the sound quality, but I found that when properly used, cables tend to sound the same, whatever the kind one decided to use. Matching impedance is the key subject of this article.

XLR, RCA, and the Magic of Matching Impedance - Audiophile ...

Audio cables/connectors themselves do not have an inherent impedance that would effect the impedance matching other than a on ohm or 3, due to resistance, depending on the length, conductor size and material, and maybe the oxidation at points where metal touches metal. Impedance matching of the source signal to the receiving device is important, but not …
What is Impedance in Audio? Input and Output …

Back in the day when audio equipment had vacuum tubes, impedance matching was crucial to ensure a good signal transfer between the different audio devices, especially in long cable runs. But in modern audio equipment, this is not a problem. Is It Necessary to Match Impedances in Audio Systems? Impedance matching has gotten easier over the years as audio equipment …
How important is impedance matching in audio applications ...
https://electronics.stackexchange.com/questions/6846/how-important-is-impedance-matching-in-audio-applications
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.

In practice, the actual telephone cables tended to have a characteristic impedance of about 140Ω, so matching transformers were employed all over the place to match between the 'standard' 600Ω, and the actual 140Ω installations. Matched-impedance Systems In The Studio Figure 2.

Impedance matching is important, even more so when the cable is long and the signals have fast rise time (or wide bandwidth). In most cases where signal integrity is important but power transfer is not (low power signals), it is sufficient to match the load impedance to …
