Re: REW Issue #1: Calibrating SoundCard


After many failed attempts last night to get this thing to work right and a short search for other MobilePre users issues, I brought my laptop and MobilePre into the office today to try some troubleshooting. I went through the following steps.
  1. Connected the 1/8' Stereo line output to the channel 2 line 1/4" input
  2. Muted the Direct Monitor, CD Player and SW Synth selections (see first pic below)
  3. Clicked the "Settings" button
  4. On the soundcard tab I clicked the measure button
  5. From there, I tried to adjust the Channel 2 knob on the front so the output and input were the same. This was ESPECIALLY problematic as the input line would move ALL over the place. I don't think I was ever able to get a steady number, so...
  6. I tried connecting to the Channel 1 1/4" input on the front. Same problem.
  7. I tried using the 1/4" mono to 1/4" mono cable connecting the Channel 1 1/4" output to the Channel 1 1/4" input. I must have got lucky, as the second time I went for a calibration file I was able to get the second picture. However, when I tried it again, NOT CHANGING ANYTHING, I go the third picture, which is similar to what I got on several other attempts (and on the first attempt).

So, any ideas as to what's happening? I'm assuming that using the one good calibration file I have won't give me good results when I actually do a sweep later unless I get lucky again.
