Well, I figured out a way to continue working towards a single signal chain and rack for my iOS rig. I have an old (very old, but sturdy) Sonic 4U rack that currently houses an older Digitech Studio S100, my BBE 362, and my GA900 IEM system. So I bought a Raxxess Universal 1U rack space shelf with the slots drilled in the bottom for bottom-mounted items, and will be installing my Audio Technica ATW700 wireless in it. Sitting right NEXT to that will be my Focusrite iTrack Solo (with a little velcro) and an extension cable for my iPhone so it will be able to be attached outside the rack, as well as a Cablejive DockStubz Plus converter so I can charge my iPhone at the same time that I am using it to process my signal. Next to the iTrack will be the DI box, front facing so all connections that need to be made will be on the front (something I liked about the DI on my GK from back in the day). All of the power components will be connected to a surge protected power supply in the back of the rack that will be velcro'd in place and have all of the wires neatly zip-tied out of the way.
The Raxxess should be here on Tuesday, I'll try to get it installed and get some pics of it after it gets here. It'll be in use (somewhat) on this upcoming weekend's festival gigs in Iowa and Illinois, so I'll let you guys know how it performs. Should be interesting. I also have an Art CleanBox Pro on the way to handle the unbalanced phono to balanced XLR conversion, and if it works the way it looks like it works, I could actually run a balanced XLR monitor signal into this at the same time and send that to the BBE, to the GA900 and to my ears.
Fingers crossed!
