RDX-MS is designed for demanding broadcast applications, combining satellite reception, IP Stream inputs, dual MPX inputs, and a high-quality FM MPX output in a single, flexible platform with multiple Input Sources
Satellite Reception - Receive and process professional satellite services with high reliability.
The receiver is designed for broadcast environments where continuous operation, signal quality, and dependable performance are essential.
IP Stream Input - Broadcast Content over IP
In addition to satellite reception, the unit supports IP Stream inputs, enabling seamless integration into modern IP-based broadcast infrastructures. This expands the available options for content acquisition and distribution, allowing operators to select the most appropriate source for their network. Satellite + IP: complete freedom in content delivery.
Dual MPX Input - Two Independent MPX Sources
The receiver features dual MPX inputs, allowing two independent MPX signals to be connected to the system. This enables efficient signal management, source selection, and integration into professional broadcast workflows.
FM MPX Output - Ready for FM Broadcast Distribution
The processed signal is available through a professional FM MPX output, enabling direct integration with FM transmission and distribution systems.
From satellite and IP reception to MPX processing and FM distribution, the Professional Satellite Receiver provides a complete and versatile solution for modern broadcast networks.
