CobraNet

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
Central Control Unit 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.
