What is Impedance in Audio? Input and Output …

What is Input Impedance? If your equipment receives an audio signal, it has input impedance. It recognizes the signal coming from the other piece of equipment. Where connected, it “sees” the output impedance from the other device. As the signal passes from one place to another, it’s called a load (load impedance). What is Output Impedance?
Why is the input impedance so high for computer …

The 10K input impedance was probably the impedance of the input amplifier circuit, not the sub driver itself...therefore it's just a normal, low-current line-level signal from the soundcard to the ...
Is there any standard for the input impedance of an audio ...

Input impedance is dependent on used resistors, in this case there's a resistor just like in the input of inverting amplifier made of an opamp. That resistor = the input impedance. The gain also depends on it. With extreme good luck the input impedance can be 20kOhm. (=component value in the example application circuit).
Sound card microphone - Hobby Hour

The typical impedance of the PC soundcard microphone input is in order of 1 to 20 kohms (can vary from card to card). The microphone type which works best with computer sound cards is the electret microphone. Sound Blaster soundcards (SB16, SB32, AWE32, AWE64 or Live) from Creative Labs have a 3.5mm (1/8 inch) pink stereo jack for the microphone input, with the …
Understanding Impedance - Sound on Sound
https://www.soundonsound.com/techniques/understanding-impedance
The DIN specification states that the current source should give an output voltage of 1mV per 1kΩ of input impedance. Typically, the input impedance of a DIN-compatible unit would be 100kΩ, and so would see an input signal voltage of about 100mV. Hi-fi equipment with phono connectors usually employs the voltage matching concept, with very low output impedance and much …

Load impedance should be around ten times the source impedance. Professional microphones usually have between 150-600 Ohms. Soundcards have between 600-2000 Ohms. In most cases impedance will not be problematic. 3. Connector and wiring scheme This is probably the most visible of the problems.

The Etymotic HF5s are 16 ohms so the max output impedance is 16/8 = 2 ohms. If you want to be assured a source will work well with just about any headphone, simply make sure the output impedance is under 2 ohms." So if the mac is 10 ohm output, you want headphones with >80ohm impedance. Share.
Line level - Wikipedia
https://en.wikipedia.org/wiki/Line_level
It is intended by designers that the line out of one device be connected to the line input of another. Line inputs are designed to accept voltage levels in the range provided by line outputs. Impedances, on the other hand, are deliberately not matched from output to input. The impedance of a line input is typically around 10 kΩ. When driven by a line output's usual low impedance of …
How to connect your computer audio output to your …
https://www.ramelectronics.net/howto-pc-audio.aspx
Assuming your computer is loaded with the appropriate computer recording software, you will need to connect the audio input of your computer to the audio output of your tape deck or cd player. We recommend a 3.5mm mini phone plug to Rca jack adapter with a RCA jack stereo cable which plugs into the "line" input of your computer’s sound card.
