Overview
Marshall Electronics VDA-108-3GS
1 × 8 3G/HD/SD-SDI reclocking distribution amplifier receives one SDI
input, perfectly duplicates it, and re-transmits eight SDI outputs for
real time multi-viewing. It is a reliable video device splitting a SDI,
HD-SDI, or 3G-SDI video source to eight SDI compliant displays at the
same time. Besides, built-in re-clocking & equalization features
provide the best performance for SDI distribution amplifier.
Features:
- 3G/HD/SD serial digital distribution
- Eight separately buffered and reclocked outputs
- Dual color LED indication of input lock and rate
- Passes all ancillary data
- Compatible with USB power sources using 3rd party adapter cables
