MuxLab 500718 - 12G-SDI 1x6 Distributor with Re-clocking and 4K/60Hz Support
The MuxLab 500718 is a professional video signal splitter designed for the most demanding broadcast and audiovisual production environments. This device allows you to take a single SDI input source—from standard definition to 4K ultra-high definition—and distribute it simultaneously to six identical, amplified outputs without any loss of quality or latency. It is the ultimate solution for engineers who need to multiply a camera or mixer signal to multiple monitors, recorders, or ingest systems.
What sets this model apart is its ability to handle the 12G-SDI standard, guaranteeing sufficient bandwidth to transmit 4K UHD (3840x2160) video at 60 frames per second . Unlike passive or lower-end distributors, the MuxLab 500718 incorporates active equalization and signal regeneration (re-clocking) technology. This means the device not only copies the signal but also "cleans" and restores it before sending it to the outputs, allowing for much longer cable runs and eliminating jitter (digital noise) that could corrupt the image in critical productions.
Its robust metal construction and gold-plated BNC connectors ensure extreme durability and optimal conductivity, essential features for continuous use in television studios, mobile units (OB Vans), or high-precision medical facilities. Furthermore, its automatic detection system adjusts internal processing to the type of signal received (SD, HD, 3G, 6G, or 12G), facilitating immediate plug-and-play operation without the need for complex manual configuration.
Main features
-
High-performance 1x6 distribution: Converts one SDI input into six perfectly synchronized outputs.
-
Full Multi-Rate Support: Compatible with SD-SDI, HD-SDI, 3G-SDI, 6G-SDI and 12G-SDI, covering all current industry needs.
-
Re-clocking and Automatic Equalization: Regenerates the signal to restore its integrity, allowing extended transmission distances (up to 45 meters in 4K 12G and up to 300 meters in SD).
-
4K Resolution at 60Hz: Supports the highest data transfer rates (11.88 Gbps) required for smooth UHD workflow.
-
Visual diagnostics: Front LED indicators for power, signal synchronization and data rate, allowing for quick identification of problems.
-
Audio and Auxiliary Data: Transmits transparently up to 8 channels of embedded audio and auxiliary data (timecode, metadata).
Benefits for the professional
-
Guaranteed signal integrity: Thanks to signal regeneration, you can be confident that the image reaching monitor number 6 is exactly as sharp as the original source, even after long runs of coaxial cable.
-
Future-proof versatility: By supporting 12G-SDI, your investment is protected for current and future 4K workflows, while remaining backward compatible with older HD equipment.
-
Connection security: The power connector has a locking system (thread) to prevent accidental disconnections in busy work environments.
-
Clean and durable installation: All BNC connectors are located on the rear panel for easy cable management in racks, while the metal chassis efficiently dissipates heat.
Use cases
-
Television and Broadcast Studios: Distribution of the program signal to multiple reference monitors, video walls and simultaneous recording systems.
-
Mobile Units (OB Vans): Signal management in confined spaces where reliability and support for multiple formats is crucial for live events.
-
4K Post-production: Sending the color correction signal to multiple client monitors and projectors simultaneously.
-
Medical Imaging: Distribution of 4K endoscopic or surgical camera signals to multiple screens inside and outside the operating room with zero latency.
-
Digital Signage: Deployment of high-quality content across multiple screens at events or trade shows.
Frequently Asked Questions
-
Does the distributor add latency to the signal?
No, the processing is real-time and designed for broadcast, so latency is virtually nonexistent and imperceptible, ideal for live production environments.
-
What type of cable should I use to get 4K?
For 12G-SDI (4K) signals, it is imperative to use high-quality coaxial cable certified for 12G (such as high-specification RG-59 or RG-6) to achieve the maximum distances indicated.
-
Do I need to configure the resolution manually?
No, the MuxLab 500718 automatically detects the input signal standard and adjusts re-clocking and equalization without user intervention.
-
Does it support audio?
Yes, the device transparently passes up to 8 channels of embedded audio into the SDI signal.
Project description
1x6 digital video signal distributor and amplifier compatible with SMPTE standards ST 2082 (12G-SDI), ST 2081 (6G-SDI), ST 424 (3G-SDI), ST 292 (HD-SDI), and ST 259 (SD-SDI). The device features one BNC input and six BNC outputs, supporting resolutions up to 3840x2160 (4K UHD) at 60Hz with a bandwidth of 11.88 Gbps. It incorporates automatic cable equalization and reclocking functions for signal regeneration, allowing transmission distances of up to 45m in 12G-SDI and 150m in HD-SDI over standard coaxial cable. It includes support for auxiliary data pass-through and up to 8 channels of embedded audio. The metal chassis houses an external 5V DC power supply with a locking connector.
