1/8 Output Impedance Rule
The voltage divider rule is used with V. Being the input to the voltage divider, and V. Being the output of the voltage divider. Since no current can flow into either op amp lead, use of the voltage divider rule is allowed. Equation 1 is written with the aid of the voltage divider rule,. Output impedance is not a fixed value. It is a curve. Meaning that output impedance varies with frequency, it will be a different value at 100 Hz and 10 kHz. Impedance tells you about the efficiency of power transfer. Now, headphones have an impedance curve, too. Impedance will vary depending on frequency. I have a 2014 Onkyo HT-S3500 basic 5.1 home theater. I am having a hard time confirming the actual output impedance of the headphone jack, but I keep seeing 390 ohm listed on Onkyo and Yamaha recievers.

Measure Output Impedance
Here's my simple explanation, but if you want an indepth understanding I recommend you read andThere are two issues with output impedance 1) interaction between the output impedance and the headphone's own impedance 2) damping factor.Here's how 1) works. Headphones may have impedance that varies across their frequency responses. Ie: at some frequencies a headphone presents the amplifier with more impedance than at others frequencies.
