GreenGo GGO-4W (4-Wire Interface)

The Green-GO 4-Wire interface can integrate the 4-Wire analog system into the Green-GO digital Ethernet network.
This audio in/out interface with contact closures connects to an existing matrix or other analogue interfacing products. A 4-wire intercom can be connected to the dual in/out 3-pin XLR ports. This allows two separate audio signals (or a stereo signal) to be injected into the Green-GO network and transmitted to any other location on the same Ethernet network.
