OK, solved my previous problem, but now I can't do a calibration because I can't reach the necessary output level before the input overloads. Like my previous problem, I'm sure that I am doing something ... stoopid. I just need someone to point out my error.

In the spirit of self-deprecation, my previous problem was solved when I realized that the MON MIX control needed to be set to "COMPUTER" to get the ... taDA! computer to play through the line outs.

If the 122 is like the 144 the input gain will need to be most of the way anti-clockwise (that end is marked "line" on the 144, the other end is marked "mic"). I also found with the 144 that turning the line out level much past the 1 or 2 o'clock position significantly increases the harmonic distortion levels.

With the 122 I found I had to push REW’s input level up to -3 or so. In the -12 to -6 range that the Help window recommended it wouldn’t work.

Actually the 122 doesn’t even need a calibration file. It’s down only 1/4 dB or so at 20 Hz.

Thanks. The problem was that I was misinterpreting the light on the input. When the light came on, I thought it was overloading. But it is only when the light turns red that O/L condition is present. I'm good now ... and I did see your post in response to someone else about not needing a cal file. However, my problem with the levels being too low would have impacted measuring.

I am good to go and looking forward to doing some measurements this evening.
