In less than one year, will mark the 2012 Winter NAMM announcement and debut of the DL1608 & corresponding Master Fader App, followed by a Summer 2012 product sales release, and the reduced I/O count model DL806 follow-up in late Summer 2013.
Fast-forward to Spring 2021, the DL1608 hardware nearly unchanged except for a Lightning Dock swapped for the original 30-Pin Dock, is currently advertised for new product purchase via many of the same dealers & resellers as then and now, albeit in a more crowded segment marketplace.
While possible that this may be NOS (new old stock), fact is, instrumental in this longevity would be the upgrades, revisions, and the recently implemented platform compatibility of the Master Fader control App/Software, combined with an assumed average or better than, history of hardware failure rates.
Looking forward to dusting off myself & mixer for some live performance music mixing on a Dell 18" PC via MF5.x and docked iPad. Cheers
