Operating Manual - nX, nXe, and nXp 150W/75W Power Amplifiers
 13 NETWORK AUDIO OPTIONS
Ashly offers a CobraNet and Dante network audio interface module that must be factory installed on nXe and nXp amplifiers.
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
software will auto-detect if CobraNet
ne
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
Protea
software on-line help, or visit the
CobraNet home
page.

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 its 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 Co-
braNet 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.
