CobraNet is a standard for the transport of real-time digital audio and control data through an Ethernet network. A CobraNet network can transport a maximum of 64 channels of 48 kHz, 20-bit audio through a 100 Mbit link connection in each direction. Many manufacturers of professional audio devices support the CobraNet standard.

The DCN Wireless digital congress network can connect to CobraNet networks with the LBB4404/00 Cobranet Interface. For example, you can use the LBB4404/00 Cobranet Interface to:

•Benefit from Ethernet infrastructure

•Transport audio signals over large distances

Note

Refer to the DCN Next Generation Installation and User Instructions for the LBB4404/00 Cobranet Interface.

PC data, for example data from the DCN Wireless Open Interface can co-exist with CobraNet data on the same Ethernet network when you use managed Ethernet switches that are approved by Peak Audio.

Note

Refer to the website of Peak Audio (www.peakaudio.com) for:

•More data about CobraNet networks.

•A list of approved Ethernet switches.
