MuxLab 500727 - 12G-SDI 1x4 Distributor - 4K/60Hz Broadcast Distribution Amplifier
The MuxLab 500727 is a professional video signal distributor and amplifier designed for critical broadcast and audiovisual production environments. This device allows you to take a single SDI input source and distribute it simultaneously to four identical SDI displays, recorders, or mixers, ensuring absolute signal integrity. Unlike conventional passive splitters, this equipment is an active solution that processes the signal to maintain the original quality without loss.
Built to withstand the demands of ultra-high-definition video, the MuxLab 500727 is compatible with the 12G-SDI standard, allowing it to handle resolutions up to 4K (3840 x 2160) at 60 Hz . Its advanced technology not only duplicates the signal but also performs automatic re-clocking and equalization . This regenerates the output signal, eliminating jitter and enabling long-distance transmission over coaxial cable without image degradation.
Its compact and robust design in a metal housing makes it ideal for both fixed rack installations and field use within mobile units. Thanks to its automatic format detection, the device instantly adapts to SD, HD, 3G, 6G, or 12G-SDI signals, facilitating integration into hybrid infrastructures where different generations of video equipment coexist.
Main features
-
Multi-Format Support: Compatible with 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI and SD-SDI, automatically detecting the input signal.
-
Real 4K Resolution: Supports video up to 4K @ 60Hz (4:2:2), ideal for modern UHD workflows.
-
Signal Regeneration: Cable re-clocking and equalization functionality that restores the signal for extended distances.
-
Professional Connectivity: Features gold-plated 75 Ohm BNC connectors for maximum conductivity and corrosion resistance.
-
Extended Range: Capable of transmitting 12G-SDI up to 70 meters, 6G-SDI up to 100 meters and 3G-SDI up to 180 meters (depending on the quality of the RG-59 or higher coaxial cable).
-
Power Safety: Includes a locking (threaded) power connector to prevent accidental disconnections during production.
-
Visual Diagnostics: LED indicators on the front panel for power, synchronization status (Sync), and data rate.
Benefits for the audiovisual professional
The MuxLab 500727 offers peace of mind in live situations. By regenerating the signal, it acts as a "repeater," ensuring that the video quality reaching monitor number 4 is identical to the original source. Its 12G-SDI capability simplifies cabling by allowing 4K to be sent over a single BNC cable, eliminating the need for four 3G-SDI cables (Quad Link) for a single UHD image. Furthermore, its support for auxiliary data and up to 8 channels of embedded audio makes it completely seamless to the existing workflow.
Use cases
-
Television Studios: Distribution of the program signal (PGM) to multiple reference monitors in the control room.
-
Mobile Units (OB Vans): Sending camera signal to CCU operators, directors and recorders simultaneously.
-
Live Events and Rental: Distribution of video signal to giant screens and projectors in auditoriums or concerts.
-
Post-production: Simultaneous viewing of 4K content on color correction monitors and client televisions.
-
High-End Video Surveillance: Distribution of high-resolution SDI security cameras to multiple security stations.
Frequently Asked Questions
-
Does the device support audio?
Yes, it supports the transmission of audio embedded in the SDI signal (up to 8 channels) as well as other auxiliary data.
-
Do I need to terminate unused outputs?
Due to the high frequencies of 12G-SDI, it is strongly recommended to use 75 Ohm terminators on unused BNC output ports to avoid signal reflections and ensure maximum performance.
-
Does it include the power supply?
Yes, the product comes with its external power adapter with a secure locking connector.
-
What type of cable should I use?
For 12G-SDI signals and long distances, it is recommended to use high-quality coaxial cable (RG-59 specified for 12G or higher) to ensure a range of up to 70 meters.
