Availability: In stock
The Extron FOX3 SR 211 Fibre Optic Scaling Receiver provides long haul transmission of DisplayPort video, stereo audio, RS-232 control, IR control, and 3D sync signals over fibre optic cabling. Engineered for exceptional high resolution image performance, the scaling receiver uses Extron all-digital technology to deliver mathematically lossless 4K/60 @ 4:4:4 video over one fibre. Designed specifically for AV systems, the FOX3 SR 211 also includes many integrator-friendly features such as EDID Minder®, audio de-embedding, Ethernet monitoring and control, and real-time system monitoring.
Uncompromised Image Quality
Supporting data rates up to 21.6 Gbps, the FOX3 SR 211 is designed to extend mathematically lossless video images up to 4096x2160 at 60 Hz with 4:4:4 chroma sampling over a fibre optic cable, making it ideal for mission-critical applications or any environment that requires the transmission of very high-resolution imagery. Maintaining a 60 Hz frame rate with a 4:4:4 Colour space provides smooth frame transitions in full-motion video and ensures the details of high-quality computer images, such as CAD drawings, are preserved.
Exclusive Vector 4K Scaling Technology
The FOX3 SR 211 delivers computer and video resolutions at selectable output rates up to 4096x2160 at 60 Hz with 4:4:4 chroma sampling. The integrated Extron VectorTM 4K scaling technology delivers best-in-class image upscaling and downscaling using exclusive, high-precision processing algorithms for exceptional scaling performance. Selectable FILL and FOLLOW modes are available to ensure the proper aspect ratio of the output. FILL mode provides full-screen output, while FOLLOW mode preserves the original aspect ratio of the input signal. Additionally, the Colour space and chroma sampling of the DisplayPort output can be automatically set to ensure compatibility with a connected display. The FOX3 SR 211 Scaling Receiver enhances the video performance of FOX3 Systems by providing the optimal output resolution to match the display and maximises system compatibility by supporting a wide range of input video resolutions.
Engineered to Streamline Integration
The FOX3 SR 211 receiver can be used with a FOX3 T 211 transmitter in point‑to‑point applications or in combination with a FOX3 Series matrix switcher for an enterprise‑wide distribution system of 4K/60 @ 4:4:4 video, audio, RS‑232 control, IR control, and 3D sync signals. To simplify integration with digital sources and displays, the FOX3 SR 211 also features many integrator-friendly features such as audio de-embedding, an Analogue audio return channel, and real-time system monitoring.
Control Signal Extension and Device Management
The FOX3 SR 211 offers convenient local and remote system access for configuration, operation, and monitoring. The front panel USB configuration port enables system configuration without having to access the rear panel. The direct RS-232 and IR insertion ports extend control signals to remote devices over the fibre optic cable. Sources and displays can be controlled from either the transmitter or receiver end using either RS‑232 or IR signals. When used with a FOX3 Series matrix switcher, the remote RS-232 port can receive inserted control data from the matrix switcher for control of the connected device. The receiver also features a LAN port, enabling the receiver to be proactively monitored and managed over the network using standard TCP/IP protocols.
Multimode and Singlemode Models for Design Flexibility
The FOX3 SR 211 is available in multimode and singlemode models. The FOX3 SR 211 MM model supports multimode fibre at 850 nm, which is typically used within buildings or facilities with moderate‑range transmission distances. The FOX3 SR 211 SM supports singlemode at 1310 nm, offering long‑range transmission capability over extreme distances. It can be used in very large facilities such as airports and stadiums, and for connecting over very long distances between facilities such as university campuses. Because transmission of content is inherently secure and immune to outside interference, fibre applications are particularly favoured in government, military, and medical environments. The receiver features industry-standard LC‑type connectivity. The 1U, half-rack width metal enclosure is designed for installation in professional AV environments.
