The state of the art DELTA-12G-elp 4c video card hosts four independent channels that can be used either as inputs or as outputs. (See the tech specs page for format- and system-dependent limitations.) The card can be purchased on its own to upgrade an existing system or kept as a spare to ensure continuity in case of hardware issues. It is fully compatible with Softron ingest and playout applications. We recommend downloading the latest drivers from the downloads section of our website. Each Softron application that supports the card provides a direct link to the appropriate driver. Detailed instructions on driver installation and card configuration are available in our Help Center. For complete technical specifications, please refer to the official Deltacast product pagee. WHAT'S INCLUDED?
