  • DATS and Calibration Hell

    Like many of you, I've had a hell of a time calibrating DATS version 1.02 to consistently work every time. It's been total hell, until today. On top of everything else, I upgraded to Windows 10, so when I needed DATS to calibrate properly in order to measure a woofer for Beau, I got nothing but crap. I thought about going back to W7, but then decided to tweak a few things to see if I could solve this issue. So, I started playing with the different settings in the Sound panel, especially the Level in the Recording tab. DATS recommends that the level be set to 1, but as I increased the level, the calibration got better, and the phase and impedance plot lines got cleaner. With my current recording level at 18, DATS calibrated in one shot, and measurements are clean. Take a look for yourself. You may want to play with the recording level in your particular set up if you're having issues. I had a lot of problems calibrating with W7, but all my computers have since migrated to Win10, so if someone can test this and let us know. Thanks.

    Re: DATS and Calibration Hell

    I've noticed it helps to plug into the same USB port every time and make sure it's plugged in before opening DATS. I let mine sit for about 1 min before trying to calibrate. After doing this, I haven't had any issues.

      Dats Hell. In Theaters this Summer.
      I have been there too but never tried any other settings. Thank you for sharing.

        Thanks for sharing. I've had mostly good luck with my dats (on Win7). Kerry has some good points that I also follow - always use the same USB port and always allow a couple minutes after plugging in before you try to calibrate and use it.


        Good luck everyone.

          I noticed that the Win10 upgrade changed my USB ports back to single channel configuration. You might check them and make sure they are set to two channel. Also, I also found that the "warm up time" is longer with Win10 - like ten minutes in my case. But after resetting the USB configuration andwaiting, the plots are smooth as butter.

            When I had a WT3 I had always set the level to about 50 in Win8 and Win10. Setting to 1 is far too low making the signal incredibly noisy, as a can be seen in Hong's screenshots.

              Try to increase the recording level higher, and your wait time will significantly decrease. I've tried this on 2 laptops now, with different USB ports, and it has consistently calibrated in less than 30 seconds. I'm a happy dude.

                    Are you all using Output level 100?

                    Well, I just tried "Recording" level 15 and it looks waaaay better. Thanks!

                    I happen to have mine set to run in "Compatibility Mode" (Windows XP SP3). I'll try turning that off next...

                    Here's RS28F measured with WT3 running in XP "Compatibility Mode" with Recording (input) level set to 15:

                    There seems to still be a little bit of a ripple problem I've highlighted with yellow highlighter.

                    I turned it up to "25" and the ripples went away.

                    OK, well in "compatibility mode" at 18 volume, in a different USB port it still had a little rippling and also stability problems.

                    I've tried a different USB port, turned off compatibility mode, and tweaked the Recording volume to "20" and seem to be getting consistent good results now...

                    RS28F with those settings:

                      My DATS doesn't seem to want to work with windows 10 on my computer.

                      Call me dumb, but I cant find the "Advanced tab of the Sound control panel" anywhere.

                        Tom,

                        Go to Control Panel, select Sound, then the Recording tab. Double-click on the DATS USB device. You should see 5 tabs, the last one is the Advanced. Set the Level to 20, and in the Advanced tab, select 2-channels, 16-bits, CD quality 44.1KHz. Hope this helps.

                          Thanks Hong, that worked.

                          I actually couldn't find the control panel, I had to do a search for it. I've only had 10 installed for about a week and I guess I'm still getting used to it.
                          It calibrated fine that time.
                          Thanks again sir!

                            The instructions posted directly from Dayton for Windows 8 indicated the recording volume for DATS should be at 54. For Windows 7 it was level 1, and for Vista it was level 25. Like others here when I tried to use a level of 1 like I was using in Windows 7 and it gave very poor results. I raised the volume to 54 and it seemed to give good results again. I hadn't tried anything in between though.

                            Here are a bunch of calibrations:

                            Volume 1



                            Volume 18



                            Volume 25




                            Volume 50



                            Volume 54



                            Volume 75

                              Here is a cumulative with level 45, 50, 54, 60, and 65 in memory 1 to 5, respectively



                              Level 50 and 54 look the best. It looks like level 50 is slightly better, but it is very close.
