Honestly sometimes having learned the analog counterpart is really useful. It's a different field but the first time I mixed live audio was on an old analog mixer. It wasn't really all that difficult to use once explained. Shortly after we replaced it with a digital mixer (behringer x32), and I'm so glad that I had the opportunity to use the old analog one because so many concepts would appear, at least to me, difficult to grasp if you're starting out on the digital one.
