NVISION CR6400 Series: Digital Router Series Datasheet (DS-PUB-3-1025A-EN.pdf) File size: 2.1 MB, posted Aug 17 2022 The NVISION CR6400 Series compact router from Grass Valley, a Belden Brand, fits 64 inputs and 64 outputs in a slim 2 RU frame and is an ideal choice for small facilities, trucks, stadiums or any location that is space-constrained such as editing suites, post-production and playout facilities. The robust matrix supports its 64-squared matrix thanks to the introduction of DIN connectors rather than the typical BNC connectors.
