I have a 5 meter rca pair connection from a desktop to a pair of rca inputs of av receiver,the rcense is at default settings 100.0 is it o.k.?

the rcense is at default settings 100.0

Sorry, I don't know that that means.

What are you trying to measure?

 

[soco]

One speaker!

 

[JohnM]

If you want to measure the impedance of a speaker it would not be connected through an AV receiver. If you want to measure the frequency response use the SPL setting, not the Impedance setting.

Ι know how to measure fr, the impedance is that i want to... can you tell me how ? i dont use external soundcard(i have usb mic for the fr. )
As i can see in the drawing i must put a sense resistor the same value that the panel displays first of all, but i dont have separate sound card so how would that be?
Just on series in one channel to the one of the binding posts (+ or - ) and the other where ?

 

[JohnM]

Your PC needs to have a headphone output and a stereo line input to make an impedance measurement. Connect up as shown in the diagram in the help. The sense resistor is in series from the right output channel to the speaker + terminal. The speaker - terminal needs to connect to the ground of the PC's input connection.

Now it makes Rsense:smile: thanks John!!
