PS-8810
DIGITAL SIGNAL PROCESSOR
CobraNet is a technology developed by Peak Audio, Inc. that
allows real time digital audio to be distributed over standard Fast
(100Mb) Ethernet hardware. CobraNet allows the PS-8810C to
not only have analogue inputs and outputs, but also to provide 8
digital Inputs and 8 digital Outputs from a CobraNet network.
These additional Inputs and Outputs allow enhanced routing and
processing capabilities, including the passing of audio channels
to other PS8810’s to create larger mixing and processing
structures.
Transmission of digital audio via CobraNet is accomplished
through 'Bundles' and 'Slots'. Bundles are Ethernet packets that
contain up to eight digital audio channels, called 'Slots'. Each
digital audio channel is assigned a position (1-8) within the
Bundle, hence the name Slot. The Bundle is then assigned a
unique number that indicates how it will be transmitted on the
CobraNet network. A receiver merely needs to select the Bundle
number to receive the audio.
Bundles can be either multicast or unicast. Multicast bundles are
sent to all CobraNet network devices, while unicast bundles are
sent to one, and only one, CobraNet network device. Through
the use of Fast Ethernet switches, unicast transmission of bundles
can greatly increase the number of bundles that can be present
on a CobraNet network since the bundles only go to the device
that is addressed. Since each device can send and receive four
bundles (i.e. up to 32 channels), great flexibility is allowed in the
routing of audio over the network. Assignment of bundles as
multicast or unicast is done through the assignment of the bundle
number. Bundles with numbers 1-255 are always multicast, while
bundles 256-65,279 are designated as unicast. Bundle
assignments need to be unique, with only one CobraNet
transmitter allowed per bundle.
The coordination, i.e. clock master, of the CobraNet network is the
function of the 'Conductor'. The ‘Conductor Priority’ is set in each
device and decides which unit will be the Conductor. If the
Conductor is removed from the CobraNet network for any reason,
the remaining devices decide who becomes the Conductor based
on a numerical hierarchy, i.e. priority ‘0’=never and ‘255’=always.
The PS-8810 is set as ‘32’ as a default.
The Conductor is responsible for ensuring that all devices on the
CobraNet network transmit their bundles in a coordinated way.
