We have a very early production unit in stock.
I tried to use one in an unbalanced situation and it had a horrible hum and was replaced with another unit. I tried every concievable transformer/grnd lift imaginable, to no avail.
Upon reading about the S/W update, one of my guys tried to update it and couldn't get it to read the USB drive. After reading Don's last post, my guess is the file name thing. So we will try again.
I want to try the computer GUI.
It is a very low budget device so I am not expecting miracles, but before I put it in an installation (we are a Peavey AA dealer) I want to make sure that it works in an acceptable, reliable manner. I would like to compare it's noise, filter response, and phase to other units, if I ever have time....
I did use it to demo (balanced=no noise) some speakers for a church and found the 5 parametric filters enough using Smaart to analyize, then used the 1/3 oct to tweak to taste. Granted, as Tom mentioned, some installs may require more parametric filters.
