    PS-8810 DIGITAL SIGNAL PROCESSOR 15.0 CobraNet ® CobraNet is a technology developed by Peak Audio, Inc. that Explanation 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.
  • Page 90 PS-8810 DIGITAL SIGNAL PROCESSOR CobraNet ® 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.
