13 NETWORK AUDIO OPTIONS
Ashly offers a CobraNet
®
network audio interface module (CNM-2), which must be factory installed on nXe and nXp ampli-
fiers. Additional network audio interface modules will become available from Ashly in the future, including
AVB
and
Dante™
.
13.1 CobraNet
®
CobraNet
®
is an Ethernet-based digital audio transport technol-
ogy 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 amplifiers can be ordered with a
factory installed CobraNet module. Protea
ne
software will auto-detect if
CobraNet is installed. The amplifier [Input Source] tab presents the Co-
branet 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 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 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 amplifier input channel.
