SDI Capture With External Audio Embedding
The Magewell USB Capture SDI Plus takes the proven SDI Gen 2 and adds the features broadcast professionals need most: an active SDI loop-through for monitoring and a 3.5mm line-level audio input for embedding external audio sources into the capture stream.
Why Choose the SDI Plus?
In live event production, you often need to combine video from an SDI camera with audio from a separate mixing desk. The SDI Plus solves this by letting you embed line-level audio directly into the captured stream — no external embedder or separate audio interface required.
The active loop-through lets you daisy-chain to a monitor, recorder, or downstream device while capturing simultaneously. Built-in cable equalisation handles SDI runs up to 150 metres for 3G-SDI, and the FPGA chip processes everything onboard so your CPU stays free for encoding.
Built for Broadcast
Enclosed in a rugged metal housing with professional BNC connectors, the SDI Plus is built for the demanding world of live broadcast and touring production. Every unit from StreamKit ships with a 3-year warranty and free UK delivery.
