I don't know jabar. The 3 graphs in post #20 show that when using headphones out (instead of line out) , the discrepancy is very slight and only occurs below 50Hz. So it may not matter much some cases. I am new to this and learning. Not trying to influence your decision, just thought that...

Here is an interesting thread where a UCA222 is used to measure impedance. The UCA222 was showing high impedance on the lowest frequencies when tested with a resistor as the DUT. Posts 6, 20, and 23 give a good summary of the most relevant information...

I am using headphone out and line in, as per REW Help. And those connections are both on the same device, the integrated sound interface. I will re-do my impedance jig. Perhaps one of my solder joints is less than perfect. If that doesn't solve the issue I will get some type of USB sound card...

Thank for your reply. I found some level controls, but was not able to make a fine enough adjustment with those to improve the input balance. Is this a common problem with older computers? On both of my computers the sound card is integrated into the mother board. Or could this possibly be...

I am using REW v5.19 which is installed on two PC's: one Win XP, the other W7 64bit. Have tried several times and keep getting error messages as shown in the attached image (percentage of level difference varies). My impedance rig is new, is comprised of quality new (clean) Monoprice RCA...

Which Dayton mic are you testing?

Thank you

Hi everyone. Great forum! 1) I am confused by the circle symbols from the diagram in REW help.. Do those circles represent the sleeve of a TRS connector? 2) How much power might the sense resistor need to dissipate? And just how "non-inductive" does it need to be? I have 100 ohm carbon film...
