Mackie had a shot at a rack configuration of the DL1608 instead they came out with the DL806 abomination. The current hardware in the DL1608 could easily fit into a 2 or 3U rack
i love this idea, but how would we be docking the ipads?
i'm having good luck with a 2' cablejive extender cable so i can plug my ipad 3 in while leaving it in its case (naked ipads and bars don't mix) but it's still just that,
luck; i have to be sure to charge to 100% before the show so the charge circuit doesn't create line noise problems, while so far the wifi alternative is still a little dodgy depending on the room.
i suspect there would need to be a more robust version of wifi technology
and a more robust (and apple-approved) cable solution before a rackmount "stagebox" version of the DL became viable.
