Hi Rickytee,
Got to be up in a few hours so I will be brief... difficult for me
Welcome, this is a great place to be for the d8b. The Owners Manual, the database, and the forum threads are a great place to start to get a feel for how to get your d8b's up and running smooth. There is really so much to it and the d8b is so flexible and variable that there is not just one way to set it up... and therein lie the beauty of this wonderful piece of equipment.
Lots of great info here, in the database, and in the manual; but honestly nothing beats just winging it and getting stuff hooked up and seeing what works and what doesn't work for your set up.
What do you plan to do with your two units? Back over 15 years ago I thought the 02R was the shizzle but comparing the two mixers... (my opinion) you did good to go with the d8b. I have a little trouble with the analog side of the mixer... others do not. For just me, I use it pretty much digital exclusive - but I do use the analog side - very flexible. I would be a fool not to use everything the desk had to offer. And not to say anything bad about the Yami 02 or the d8b analog side, it is just how I utilize its functions. For the most part I use the digital routes and for ease of "what needs to happen" I will route through the analog. Nothing wrong at all with it for some things. If I was to go with an analog mixer it would not be the d8b lets just say.
Probably didn't answer one question but I replaced both the CPU and Power supply fans for good measure, got new ram, secured "new" hard drives and replaced the floppy with a new one (battery too) and a re-format of hard drive, after saving session files of course, and a fresh install of the OS - unlocking all the plugs I have codes for... etc.
If you are going to become proficient at this thing you need to read and do... That is my advice.
Hope this helps,
Michael
