In the event that you might have a need to do a crash course on the SSL G Series console pictured below I have good news. SSL has put up a shortform overview on the board here. Don’t worry about the registration step. The pdf file will download just fine without any registration required. I was asked to help out on a session with a G and it had been a while since I had worked on that class of console. A good refresher. And, if you are interested in getting a sense as to why studios still use these types of consoles over say Behringer and Mackie, then the overview will give you some hint as to the complexity and capability of the G platform.
The SL 4000 is a standard in music recording studios worldwide. And, according to Billboard magazine, almost 75% of US No. 1 singles (Hot 100) were recorded on G series consoles.
