Grass Valley NV8500 Series v.3.5 - Manual (Page 17)

Introduction
NV8500 series routers offer a highly flexible switching architecture. A single router can switch
both audio and video signals. NV8500 series routers receive and send audio and video signals
on a single I/O card. The hybrid architecture of the NV8500 routers can disembed audio from its
video inputs, recombine audio from multiple inputs, and re-embed audio at its video outputs.
The NV8500 series routers can also switch MADI channels and embed the channels in video
outputs.
NV8500 series routers, as do all of Grass Valley’s NVISION series routers, employ a fully non-
blocking architecture.
The NV8500 series includes these routers:
NV8144 — 144 inputs × 144 outputs, nominally
NV8140 — 144 inputs × 288 outputs, nominally
NV8280 — 288 inputs × 576 outputs, nominally
NV8576 — 576 inputs × 1152 outputs, nominally
NV8576-Plus — 576 inputs × 576 outputs, nominally
Expanded NV8576-Plus — 1152 inputs × 1152 outputs, nominally
The matrix sizes represent the number of standard outputs the routers support.

About the NV8500 Series Routers
Each NV8500 series router, with the exception noted, can switch these signal types:
• SDI (SD, HD, and 3Gig)
1
The router’s 3Gig inputs can also receive HD and SD signals. Similarly, the router’s 3Gig out-
puts can also transmit HD and SD signals.
• MADI
The routers receive and transmit MADI signals, but extract the audio from the MADI streams
and perform the switching on the audio signals internally.
• AES async
The NV8140 does not switch AES async at this time.
