The Pro Tools HD Native + MADI Bundle by Avid is a complete system for Mac and Windows that facilitates integration of Pro Tools HD into broadcast and post-production environments.
The Avid HD MADI interface can send and receive up to 64 audio streams between Pro Tools HD and connected MADI devices at distances of up to 1.24 miles (2 km). All inputs and outputs provide sample rate conversion, which greatly simplifies workflow.
You also get the HD Native PCIe card, which serves as the bridge between your computer and the HD MADI interface, by way of two included DigiLink Mini connection cables (32 audio channels each; cables and adaptors included).
