As a user of the Ramsa WR-DA7 since June 1998, I have decided to write a series of essays, application notes, and new feature suggestions about the DA7 console.
The unofficial DA7 user group page is a great place for information. That page has links to manufacturer sites, downloads, and reviews, but its biggest thing is a very helpful and active user message board. (And, a couple of the manufacturer's people participate, which is a Good Thing.)
Using web pages, it becomes fairly easy for me to write in a stream-of-consciousness style about whatever topic comes to mind, inserting appropriate links to different discussions where needed.
Everything mentioned in these pages applies to the 2.0 version of the DA7 firmware.
