The CobraNet card is used to output audio via Ethernet, which may then connect multiple speakers. This cuts down on the number of output ports built into the Delta unit, but still allows for multiple audio outputs.

This section shows how to install the CobraNet Card in the Delta Server.

CobraNet transmits the audio from the Delta server (or other pc) to a single or multiple CobraNet receivers, using Bundles (ranges) to distribute the audio to their channelled output devices.

In this example, our receiver is a second server, connected via Ethernet cable, to test audio output (using the Motherboard audio and headphones).
