Default First time with ARTA - am I set up correctly for amp measurment?

I'm just starting to use PC base tools. I picked ARTA to try first. I want to measure THD, etc in my preamp and amp.

I built the measurement box as seen at:

HiFi Measurement

My question is this: If I want to measure my amp, I don't need the speaker and mic hookup correct? I just take line out to the amp being measured, then connect the output of the amp to the measurement box (has a voltage divider), and connect the output of the box to the line in of the computer. Then generate noise and get the THD measurements?

Yes. But you should use a dummy load on the amp. 8 ohms or whatever your normal load.
You can also measure with the loudspeaker as a load, to see the differences.
