Item description for Polycom Vortex EF2280 8 Channel Telecom Conference System Matrix Mixer w/Adapter

Polycom Vortex EF2280 8 Channel Telecom Conference System Matrix Mixer

This was surplus from a community college. It powers on and I get several different displays when I play with the buttons. I don't have the cables or components to test this further. This does come with an AC adapter. Everything that it included is shown in the pictures.
