BDLKHDEXTR4KQUAD • For DeckLink 4K Extreme 12G • 4x BNC 3G-SDI • Mezzanine / Daughter Card
This listing is for a Blackmagic Design DeckLink Quad 3G-SDI Mezzanine Card (BDLKHDEXTR4KQUAD), ideal for broadcast engineers, video production facilities, post-production studios, systems integrators, repair shops, and resellers working with Blackmagic DeckLink hardware.
This is the optional Quad 3G-SDI daughter card designed to replace the original mezzanine card on the DeckLink 4K Extreme 12G PCIe main board. It adds four BNC connectors supporting Quad Link 3G-SDI — two inputs and two outputs — that work in conjunction with the four 12G-SDI connectors on the main board. It supports converting a 12G-SDI input to a Quad 3G-SDI output. Requires DeckLink driver version 10.4.2 or later.
Important: This mezzanine card is not a standalone product. It requires the DeckLink 4K Extreme 12G main PCIe board to function. The main board is not included.
Serial number is recorded for verification and packing accuracy.
