Dante Clocking
The Dante network uses a master/slave clocking architecture - there is a single master clock and everything else receives it's clock from there. The system can choose it's own master clock, or preferred masters can be defined. Some of the RedNet devices can also slave to external clocks. In URY, the Dante network master device is the RedNet 3 (Stores), which is in turn slaved to the Focusrite Scarlett 18i20 (USB'd to the broadcast server). When correctly configured, urystores is set with both "preferred master" and "enable sync to external" checked in Dante Controller, whilst in RedNet control, "Clock Source" should be "External" and "External Word Clock Source" should be "Word Clock Input".
This was chosen as the clock master so in the case of network issues, or devices being added or removed from the network, the Scarlett doesn't break audio to the transmitter as it re-syncs it's clock (it's the master, so doesn't have to sync). The Dante network is slaved to this so the ADAT audio links between the Scarlett and RedNet 3 don't have glitchy audio.
Rednet units are known, at URY at least, to have Switch Mode Power Supplies that seem to fail unusually often - the Rednet 2 in Studio Red has had its PSU replaced by Focusrite twice now, and similar issues are now manifesting themselves with the Rednet 3 in Stores.
