Hi Steve,

All you need to do is scroll a little further down the software page http://www.Meridian-audio.com/lib_soft2.htm
and you will see 568.2 public beta. All the downloads and directions are there to download.

You'll see 500 series, then DSP loudspeakers and voila! 568.2 Public Beta!!

You will have to download the meridan.exe file to replace with the file in your current setup directory.

It's a Beta version so not so straight forward and upgrade.
