I worked five years on Mackie Dl1608 and now I decied to take dl16s. We use backing tracks in our shows, and with them, drummer has a click. So now I don’t need an aditional router, aditional mixer for drummer’s aux and aditional sound card. 
I like dl1608, but dl16s is better with it’s features. Just turn the cable into a Mac, and all is ready. 
 
*Master Fader is easy to use and I can make very fast all routings I need. 
*Good preamps, good sound, very easy to use. 
*2.8kg. 
*Good quality of the box, Mackie connectors, not “shunsheng” :) 
 
I have four mixers from Mackie. Two analog and two digital. I like them. 
 
Many thanks for Thomann team. The mixer was delivered in a week to MD. 
 
After 6 months of use I can add some things: 
In this period I had some trouble with connection, but I changed wi-fi channel and upgraded all devices to Master Fader 5.2. Now it connects and works perfectly with internal router. It works from mac, ipad and android device like a mixer, and like a interface with 3 stereo backing tracks and one mono for click. 
Love it!
