13.1 CobraNet®
CobraNet is an Ethernet-based digital audio transport technology de
-
veloped and supported by Cirrus Logic. It is a combination of software,
hardware and network protocols which allows distribution of multiple
channels of real-time, high quality digital audio over a standard Ethernet
Network. Ashly nXe or nXp amplifiers can be ordered with a factory in

stalled CobraNet module. Protea
ne
software will auto-detect if CobraNet
is installed. The amplifier [Input Source] tab presents the Cobranet audio
routing and source controls as well as the status of individual receivers,
bundles, and channels. For more detailed information, please search

Basic Terminology
Cobranet Receiver:
There are four
receivers A, B, C, and D in amplifiers
with CobraNet installed. Each receiver
can receive one Cobranet bundle
selected by the user. It is not necessary
to use all receivers. Depending on
how audio is sent from the CobraNet
transmitter, a single receiver can be
used and it's selected bundle and
channels routed to individual amplifier
inputs using the Cobranet matrix in the
input source tab.
Cobranet Bundle:
A Cobranet bundle
is a group of up to eight audio channels
which are transmitted together from
a single Cobranet device and may be
received by several Cobranet devices.
Each bundle is assigned a bundle
number. This number can be in the
following ranges:
0:
Bundle is disabled.
1 to 255:
These are multicast bundles
and are not recommended for most
situations.
256 to 65279:
These are normal uni-
cast bundles and are most commonly
used.
65280 to 65535:
These are "private" bundles and should not be used.
Cobranet Channel:
Each bundle can contain up to 8 audio streams, or Cobranet channels. They are labeled 1 to 8. The Cobranet
channel number within the bundle that was assigned to the desired audio source is the same bundle and channel number that
should be selected when extracting and routing that original source to an amplifier input channel.
