The 4 RU Densite 3+ FR4 Frame from Grass Valley, a Belden Brand, is a modular frame and controller designed to deliver more power per slot and higher speed connectivity needed by the increased feature set of the latest Densité products. The Densité 3+ FR4 frame offers true multiformat operation, with the ability to process simultaneously SDI and IP 4K, 3G, HD, SD, and analog video, as well as AES and analog audio. The frame provides advanced monitoring and back-up capabilities along with a color LCD panel with integrated touchscreen for ease of status and control navigation on the front panel. The front-opening frame features dual hot-swappable power supplies (PSUs) and fans. The processing modules or cards for the frame are also hot-swappable, and can be configured automatically when a card is replaced. The frame is front-to-back air-cooled and all modules, redundant PSUs and fans are monitored to provide status via GPI or the Ethernet port. The basic frame configuration includes one PSU and a controller card, which allows card parameters adjustments from the front panel.
