About this product
The Magewell USB Capture SDI Plus adds an active SDI loop-through and a line-level audio input, letting you embed external audio from a mixing desk directly into your captured stream.
Built for professional broadcast environments where SDI monitoring must continue uninterrupted while capturing, and where external commentary audio needs embedding without a separate audio interface.
