I have an NSB 16.8 connected via a Cat 6 ethernet cable to my StudioLive 16 Series III. I've gone thru the stage box setup process and assigned inputs and outputs as directed in the instructions. I have a blue light on the NSB indicating it is connected to the network and a green dot next to the NSB on the display of the StudioLIve 16. When I connect a microphone to any of the inputs on the NSB I get absolutely no signal on my StudioLive 16. What am I missing? Are there any tricks to getting this to work?
