Connected to your Fairlight Audio Accelerator, the Blackmagic Design Fairlight PCIe Audio MADI Upgrade adds 192 channels of MADI I/O to your DaVinci Resolve 17 system, raising the total MADI channel count to 256 inputs and outputs. This half-length card uses no additional PCIe bandwidth and hooks up to the Fairlight Audio Accelerator (required and available separately) through the supplied SATA cables.
