I have been away from testing for a while.
Last night I set my laptop and Saffire 6 USB, and started basic testing.
Here's the problem; Arta (STEPS) is measuring ~160dB output from the speakers. Obviously that's wrong.
When I disconnected the microphone, Arta measures 60 dB 20Hz -20KHz with no input.
I think I've checked everything, but this solution eludes me.
Help.
I am using an Asio driver.

Did you calibrate your setup? There is a calibration procedure in ARTA.
Unless you are interested in absolute values, there is no reason to worry about whether it reports 160db or 90db.

Thank you ra7.
I did re-calibrate, but I must have left something undone. It's that 'undone' thing that I can't figure out.
I do realize the 160dB isn't an issue, except that the rises and drops in the response' are slightly exagerated. Maybe I will just reduce the range (bring 150dB - 170dB closer together), and flatten stuff out.

Right. I would say a 70-80db range, with 5db divisions is good on the eye. Unfortunately, I've never gotten ARTA to do show 5db divisions.
Did you put in the mic response compensation file?

ra7, I don't have a mic response compensation file. I'm using the Beheringer 8000. Where would I find such a file?.

The calibration files here are generic and 1/3rd octave smoothed. You have to register to download files or even view content. The Dayton EMM6 mic, which is essentially a copy of the Behringer comes with a custom file unique for each mic. And it can be downloaded from the Dayton Audio website.
You can send your mic to Cross Spectrum Labs and get a calibration file for your mic. I would suggest using the generic file for now, save up and buy the Dayton EMM6. It's not that expensive.
This will only compensate the frequency response of the mic. You still won't get absolute SPLs. For that you need a sound level calibrator: http://www.amazon.com/Reed-SC-05-Calibrator-Diameter-Microphones/dp/B008S0OVR2
