Explore this buying guide ↗Why consider this model?
- A PCIe workstation candidate for multiple SDI ingest or playout paths when the source uses SD/HD formats and standard BNC cabling is part of the existing signal chain.
Tradeoffs to weigh
- It is SDI-only and tops out at the documented SD/HD family through 1080p60; four configurable ports do not establish four simultaneous streams at every peak rate. It is an internal x4 card, not a USB device, and the source does not document HDMI loop-through or exact package cabling.
