About the Grass Valley, Miranda EM0785-02A1 3Gig SDI 18 Coax OUT
The Grass Valley (Miranda) EM0785-02A1 is a high-density coaxial output module designed for integration into the company's professional modular router and signal processing frames, such as the iControl or NVISION series. Its primary function is to serve as a bank of eighteen independent 3G-SDI (Serial Digital Interface) reclocked outputs, providing robust, high-quality signal distribution from a central routing matrix. Each output on the module is driven by its own dedicated reclocker, which actively regenerates the incoming SDI signal to restore its amplitude and timing. This process removes jitter accumulated from internal router crosspoints and ensures that the signal meets broadcast specifications for long cable runs to downstream equipment like monitors, recorders, or transmission encoders.
The module operates within the broader ecosystem of a Grass Valley routing system, where it would typically be paired with input modules and controlled by a central control system. It supports the full SDI suite, including standard definition (SD-SDI), high definition (HD-SDI), and 3G-SDI (which carries 1080p60 signals), ensuring backward compatibility and future readiness. The reclocking capability is crucial in large facilities as it maintains signal integrity across complex signal paths, effectively acting as a distribution amplifier for each output. This allows a single routed source to be fed to multiple destinations without signal degradation, which is essential for mission-critical broadcast, production, and post-production workflows.
Housed in a single, slot-efficient module, this unit exemplifies the broadcast industry's need for density and reliability. It is engineered for 24/7 operation in demanding television stations, mobile production trucks, and media centers. By providing eighteen independently buffered outputs in one module, it maximizes the number of feeds available from a router while minimizing rack space and power consumption per output. This module is not a standalone device but a core component of a professional broadcast infrastructure, representing the high-performance, redundant, and scalable backbone required for modern multi-format video production and distribution.
