ka 7300 headphone output impedance

post #1 of 4
Thread Starter 

hello! I've a simple question: if an integrated amplifier has  a damping  factor of 50 on a 8 ohm load, what is the headphone output impedance if it is obtained putting a 330 ohms resistance in line with speaker output? thank you

Why would you wanna put a 330 ohms R in series with your headphones???

HI again you :) now I have a GPINTO and i'm not using this  amp ti drive my hd 800, but however this is how  is obtained the headphone output by   kenwood, I don't wanna do anything ;)

Don't do it, it is unecessary.

It shows poor understanding of electronics circuit design on the part of Kenwood engineers.

Use the GPinto instead, as it is 10000x  better.

 

cheers
