That looks like a power light not an IR receiver to me, IR receivers areblack (well really really dark red actually for the Infrared light transmission) and not greenish.
EDIT: I was correct that is a power light, just saw this unboxing video on the Ferrum site:
Ferrum ERCO Unboxing - It just become a thing!
A 2nd EDIT: I am happy to see them do away with the 4-pin XLR balanced output even though most of my headphone cables are 4-pin, the industry needs to go away from 4-pin for headphone connections, it is overkill, over consuming (materials wise), and over with now that 4.4 balanced is adopted from the AM Cable Community!
