MuxLab 500728 - High Performance 12G-SDI 1x8 Distributor (4K/60Hz)
The MuxLab 500728 is a professional video signal distributor and splitter designed for critical broadcast and audiovisual production environments. This device allows you to take a single SDI input source and simultaneously distribute it to eight identical outputs , maintaining signal integrity without loss or latency. Its ability to handle high bandwidths makes it an indispensable tool for 4K Ultra HD workflows at 60 frames per second (4K/60Hz).
Built with a robust architecture, this equipment not only splits the signal but also acts as an active regenerator. It incorporates advanced reclocking and automatic equalization technology, allowing it to automatically detect the type of incoming signal—from standard definition (SD) to the most demanding 12G-SDI—and regenerate it for long-distance transmission. This eliminates the jitter and signal degradation that typically occur in long coaxial cable runs, ensuring that each of the eight connected monitors, recorders, or mixers receives a crystal-clear and stable image.
Its compact design in a metal chassis ensures durability and protection against electromagnetic interference, ideal for fixed installations in studios or for rugged use in mobile units and live events. Furthermore, the gold-plated BNC connectors guarantee optimal conductivity and corrosion resistance over time.
Main features
-
1x8 Distribution: Single BNC input that is replicated into 8 simultaneous, perfectly synchronized outputs.
-
Multi-format support: Compatible with 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI and SD-SDI.
-
4K/60Hz Resolution: Supports resolutions up to 3840x2160 at 60Hz (4:2:2), ensuring compatibility with current ultra high definition standards.
-
Signal Regeneration: Integrated re-clocking and cable equalization functions to extend transmission distance (up to 70 meters in 12G-SDI and 180 meters in 3G-SDI).
-
Automatic Detection: The device instantly identifies the data rate of the input signal (1.485, 2.97, 5.94 or 11.88 Gbps).
-
LED Diagnostics: Visual indicators for power and signal lock status for quick monitoring.
-
Secure Connection: Includes a locking (threaded) power connector to prevent accidental disconnections during operation.
Benefits for the professional environment
For video engineers and broadcast technicians, reliability is non-negotiable. The MuxLab 500728 offers the peace of mind of knowing that the source signal will arrive intact at multiple destinations. Automatic equalization simplifies installation, requiring no manual adjustments regardless of cable length (within specified ranges). Furthermore, its backward compatibility allows for the integration of legacy equipment (HD cameras or SD monitors) into modern 4K infrastructures without the need for additional converters, maximizing equipment investment.
Use cases
-
Television Studios: Distribution of the program signal to multiple reference monitors, video walls and recorders in the control room.
-
Mobile Units (OB Vans): Signal management in confined spaces where robustness and 12G support are required for 4K sporting events.
-
Post-production: Sending the editing signal to color correction projectors and client monitors simultaneously.
-
Live Events and Rental: Video distribution to multiple giant screens or projectors in auditoriums and concerts, ensuring no signal dropout during long runs.
-
High-End Video Surveillance Systems: Distribution of high-resolution SDI cameras to multiple security posts.
Frequently Asked Questions
-
Does the device include a power supply?
Yes, an external 5V DC power supply with a locking connector is included for added safety.
-
What is the maximum cable length it supports?
It depends on the cable quality (RG-59 or higher is recommended) and the resolution. It can reach up to 70 meters for 12G-SDI (4K) signals and up to 180 meters for 3G-SDI (1080p) signals.
-
Does it support embedded audio?
Yes, the distributor passes the full signal, including up to 8 channels of embedded HD audio and auxiliary data.
-
Is it HDR compatible?
As a transparent distributor that complies with SMPTE ST-2081 and ST-2082 standards, it allows the passage of metadata associated with the video signal, provided that the source and destination are compatible.
