Introduction
NV8500 Review
routers can disembed audio, recombine the audio, and re-embed the recombined audio at
output.
With DHP (dynamic hybrid pathfinding), the routers can route standard input through an
internal pool of hybrid disembedder cards and embedder cards after which the audio from the
standard input can be recombined and re-embedded on output. The point of DHP is that it
allows you to populate the router with many relatively inexpensive standard I/O cards and a few
hybrid cards and still have the benefits of hybrid routing (the ability to breakaway audio entirely
within the router).
I/O Cards
Each router has a certain number of input card slots and a certain number of output card slots:
You may populate the slots with any type of input or output card your system requires.
Input cards are coupled with input backplane connector modules (or backplanes, for brevity).
Output cards are coupled with output backplanes. Backplanes typically have coax (DIN 1.0/2.3)
connectors or fiber optic (SFP) connectors. (Balanced AES modules use WECO quick-release
connectors.):
