Dante Ports
The network audio ports. Either port can be used with 
a single network connection. When a second network 
is configured for redundancy, all processors connected 
to the network must have consistent connections, i.e. 
all Primary ports connected to one network and all 
Secondary ports connected to the other network.
Mic/Line Inputs
Analog inputs with adjustable gain from -10 to +60 
dB in 1 dB increments; balanced differential floating 
design (no pin 1 problem).
