Tim - You bowed out too early!!! Your H-Bus hunch proved to be the clue that cracked the case. Guess what? This unit used to be part of a 24 channel audio rack. And... what for it... this unit had the dip switch set to 1111000000. I set it to 1000000000 and the LEDs lit up, all 8 channels are receiving input. FYI No analog volume tab shows up - the audio is coming in on the monitor input tabs on the envy24 mixer. Thank you so much for your help.
