Measuring High Impedance Sources - Audio Precision
https://www.ap.com/technical-library/measuring-high-impedance-sources/
Measuring high impedance sources, such as some high impedance audio transformers, can result in poorer high-frequency performance than expected. This is due to an input shunt capacitance of around 190–300 pF that is present in almost all audio analyzers. AP’s APx500 Series has a shunt capacitance of 220–230pF, while the 2700 Series has a shunt …
Understanding Impedance - Sound on Sound
https://www.soundonsound.com/techniques/understanding-impedance
In a voltage-matched system, two tape machines can be connected to the same console without an appreciable drop in level at either of the machines — the two parallel 30kOhms impedances are seen as 15kOhms by the source, which is still very high compared to the 150 Ohms output impedance. Relatively high-impedance inputs such as these are called bridging inputs, and …
High and Low Impedance Signals - Support - Whirlwind
http://whirlwindusa.com/support/tech-articles/high-and-low-impedance-signals/
A high impedance microphone or guitar will usually output a greater signal (voltage) than a low impedance microphone. This high impedance signal works fine and even has some advantages in a sound system as the mixer or amplifier doesn't need to boost the signal as much. Therefore, any noise on the line is also not amplified as much and this results in an improved signal to noise …
What Is Speaker Impedance and How Does It Work? - Audiosolace
https://audiosolace.com/speaker-impedance-explained/
The word impedance is based on the output current of an amplifier, which is usually AC and not DC, as the latter is found on batteries instead. The amount of impedance indicated in an audio source such as your home theater main unit or even your MP3 player shows the amount of audio signal it sends as AC.

The source impedance usually is low, mostly ranging between 0-4 ohms but can go as high as 120 ohms in some specialized amplifiers. Mainly, manufacturers indicate the nominal impedance of a pair of cans and can vary in magnitude (ohms) and phase (degrees) as the sound frequency ranges vary.
What is impedance? | Ausounds

There is a large variety of different headphone amplifiers and portable audio players that have higher electrical output, but as mentioned earlier, impedance also occurs in the audio source. High impedance headphones are usually estimated at 25 ohms and above.In regards to Moore’s law, technology is simply getting better and better.

Headphone Impedance Demystified: Do I Need a …
https://www.headphonesty.com/2019/04/headphone-impedance-demystified/
Headphone impedance is typically rated between 8-600 ohms, with a standard around 32 ohms becoming increasingly common. Audio source impedance is typically very low, often less than 4 ohms and approaching 0 ohms in many cases, but it may be as high as 120 ohms or more for specialized tube amplifiers, specifically output transformer-less (OTL) types.
Why is high input impedance good? - Electrical …
https://electronics.stackexchange.com/questions/21787/why-is-high-input-impedance-good
For high impedance sources "suitably) needs to be quite large. A high impedance input places very little load on a signal that is applied to it. It thus does not reduce it in level (or not much). A unity gain buffer usually has very high impedance and …
