The Marshall VDA-108-3GS sends one SDI feed to eight independently buffered outputs. It supports SD, HD and 3G-SDI with reclocking and equalization for distribution to several receiving devices. Status indication helps an installer check the incoming signal at the distribution point.
Marshall VDA-108-3GS Features
- Eight destinations from one feed. One SDI input supplies eight outputs, allowing the same source to reach multiple monitors or recorders. This reduces the need to route the feed through a chain of receiving devices.
- Separately buffered outputs. Each output has its own buffer. This provides distinct distribution branches for the receiving devices instead of treating all destinations as one shared passive signal connection.
- SD, HD and 3G formats. Support for SD-SDI, HD-SDI and 3G-SDI includes Level A and B operation. The amplifier can be used across several common baseband video standards within its supported format range.
- Reclocking and cable equalization. The unit reclocks the signal and specifies equalization up to 300 m for SD or 150 m for HD/3G with suitable cable. Actual installation planning must account for the cable used.
- Ancillary data transport. Ancillary data passes through with the incoming SDI feed. This retains associated signal information for downstream devices that use it, rather than limiting distribution to picture data alone.
- Input status and low consumption. A dual-color LED indicates input lock and rate, providing a quick check at the box. Stated consumption is less than 1.25 W with all outputs loaded.
