Quadbox 4X4 Coax Mini-Switcher

project posted:


PESA’s QuadBox 4X4 Coax Switcher works as a mini-switcher for small venues or can be used as a secondary switch fabric as part of a larger routing system. With its small size, the QuadBox 4X4 easily fits in many out-of-the way locations. The unit allows any coax input to be switched to any output. High defintion video signals for ASI/SDI, HD-SDI, or 3G-SDI can be passed through each port. The Quadbox 4X4 is compliant with SMPTE 259M, 292M, 372M and 424M.  Each Quadbox supports high defintion video with or without embedded audio and data, as well as DVB/ASI The Quadbox 4X4 switch works with all PESA HD router systems. Each Quadbox comes with a built-in Ethernet port and USB port for easy setup and diagnostics. Up to four modules can be loaded in a 1RU frame with support for redundant power. Setup is simple with the supplied GUI interface.
