PS-8810
DIGITAL SIGNAL PROCESSOR
The Conductor recognizes each device on the network and assigns
a transmission position for each bundle of each device.
In addition the Conductor sends master clock to each device to
ensure that all audio is synchronous. Like a conductor of an
orchestra, the Conductor signals the beginning of a synchronous
transmission cycle, and then each device sends its bundle(s) in lock
step. This occurs 750 times a second, with each audio channel
having 64 samples of 48KHz audio. Each audio channel can be
sent as 16, 20, or 24 bit samples. if 24bit audio is used then a
bundle will be reduced to 7 channels. There is a fixed latency of
5.33ms.
CobraNet networks utilize Fast (100Mb) Ethernet hardware and
can use either repeater hubs or switches. A repeater hub is a
device that takes the data that comes into each port, and sends it
back out on all ports except the port in came in on. As a result,
only multicast bundles can be used in repeater hub networks and
these need to be limited to 8 bundles per network.
On the other hand, switches are much more efficient, in that they
examine the destination address of each packet of data received
on each port, then switch that data to the particular recipient of
that packet. Unicast bundles exploit this feature to minimize the
audio traffic on the CobraNet network. The result is that an
almost limitless number of unicast bundles can be on a switched
CobraNet network. Multicast bundles are allowed on a switched
network, but they must be used with care.
Peak recommends that not more than four multicast bundles be
used in a switched CobraNet network. Peak also advise not to
mix ordinary computer data on a repeater hub network, as this
could result in dropout in the audio. In switched CobraNet
networks, coexistence of CobraNet audio and ordinary computer
data is possible, because there are no collisions with the audio.
If there are only two PS-8810 units involved in a CobraNet network
these can be connected using CAT 5 crossover cables.
