Potentiometer output impedance vs headphone impedance
Forgive my ignorance, but I'm building a volume controller with a potentiometer, and I'm having thoughts about the high impedance
I understand that:
Headphone jack (low imp) >> pot. (high imp) is fine.
but wouldn't having the pot at say 15kOhm for example, load down the headphones
pot (15kohm) >> phones (55ohm) == bad??
Cause now the output impedance is much higher than the input.
So all these questions are racing to me.
Does only the impedance the headphone jack out sees matter? Does the potentiometer somehow have a constant output impedance I'm not aware of?
Couldn't I technically throw a 50ohm resistor between the potentiometer and the phones to balance the impedances?
