The analog Thru connectors let you route the incoming signal on to
a downstream amp. The built-in switch severs the signal-carrying
line's ground circuit.
The two Ethernet ports serve control purposes and as an interface
for the Dante® interface. The Ethernet ports may be used as a
switch in conjunction with the amp platforms and as redundant
ports for the Dante interface.
