Feed this into an "input L&R" of you preamp, turn up the volume on your preamp to where you normally listen to.
And measure the preamp "output" one channel first (center to outside rca) with an AC volt meter set to 2v full scale, then adjust the website volume so your at say 1v or 1.5v then measure the other channels output. to see if it’s the same.
Cheers George
