Operating Manual - nX, nXe, and nXp Power Ampliers
 13 NETWORK AUDIO OPTIONS
Ashly offers a CobraNet and Dante network audio interface module that must be factory installed on nXe and nXp ampli-
ers. AVB will become available from Ashly in the future.
13.1 CobraNet®
CobraNet is an Ethernet-based digital audio transport technology
developed 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 ampliers can be ordered with a factory in-
stalled CobraNet module. Protea
ne
software will auto-detect if CobraNet
is installed. The amplier [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
Protea
ne
software on-line help, or visit the CobraNet home page.
Basic Terminology
C o b r a n e t R e c e i v e r :
There are four receivers A, B, C,
and D in ampliers 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 amplier inputs using the
Cobranet matrix in the input source
tab.
C o b r a n e t B u n d l e : 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 unicast 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 amplier input channel.
