MuxLab 500728 12G-SDI 1X8 Splitter
Overview
The 12G-SDI 1×8 Splitter, 4K/60 (500728) allows one (1) 12G/6G/3G/HD/SD-SDI source to be distributed and amplified to up to eight (8) 12G/6G/3G/HD/SD-SDI displays. The splitter supports up to 4K (3840 X 2160) video and HD audio, including 480i (SD-SDI), 720p/1080i (HD-SDI), 1080p (3G-SDI), 4K/30 (6G-SDI) and 4K/60 (12G-SDI). The device automatically detects the 12G/6G/3G/HD/SD-SDI signal and reclocks and regenerates the signal at the output for extending distances between source and displays. Additionally, all connectors are on the rear panel for neater cabling.
Applications
Applications include video production, broadcasting, outside broadcasting vehicle, SDI camcorder, studio-to-studio, post-production, live events, medical imaging display, mobile video.
Installation
- Identify the connectors on the 12G-SDI 1×8 Splitter as indicated on the product labels above.
- Connect the source to the 12G-SDI Input of the splitter.
- Connect up to eight (8) display(s) to the 12G-SDI Outputs of the splitter
- Connect the 5 VDC power supply to the splitter first, and then plug the power supply into an AC power outlet. If power is present, the power LED of the splitter will be illuminated.
- Note: Power ON the 12G-SDI 1×8 Splitter, 4K/60 only after all connections are made.
- Power the equipment and verify the image quality.
- The appropriate Data Rate LED will be ON to show the input signal rate speed and that the signal is locked.
- The following diagram shows the final configuration.

Output Pairing
The outputs of this device work in pairs Due to the high frequency and low jitter requirement for 12G-SDI signals, to have the best performance it is strongly recommended to use a 75ohm terminator if a paired SDI output port is not in use. Please see the following table for the 12G-SDI output pairing:
| Output Port | |
| Pair A | Output 1 & 2 |
| Pair B | Output 3 & 4 |
| Pair C | Output 5 & 6 |
| Pair D | Output 7 & 8 |
Troubleshooting
| Symptom | Probable Cause | Possible Solutions |
| No Image | No power | • Check power connections |
| No Image | Source | • Check if the source is sending a signal. |
| No Image | Resolution | • Check if the source resolution is valid. |
| No Image | Coaxial Cable | • Check the coaxial cable. |
| No Image | Coaxial Cable distance | • Check the coaxial cable distance for the corresponding resolution (see Specifications table). |
| No Image | Coaxial Cable Quality | • Check the coaxial cable type. It should be an RG-59 or better coaxial cable. |
| Flickering Image | Synchronization | • Check the coaxial Cable Quality or distance. |
| Choppy sound | Synchronization | • Check the coaxial Cable Quality or distance. |
