I know we talk all the time about the ua-5 and its modification for satndalone operation without a computer. Well, I was looking on ebay at the huge selection of a/d converters with xlr ins and various out and spec, etc.....and was wondering if there are mods that can be made to all of these (or any of these) other converters so that they, just like the ua-5, can operate w/o a computer?
