The next generation of Pro Tools|HD is here! The HD MADI from Avid gives you 64 channels of MADI connectivity. Boasting bi-directional sample rate conversion, the HD MADI makes sure your ICON or Pro Tools|HD rig can slide into any MADI environment, at any sample rate, and hit the ground running. Since you have 64 channels of MADI I/O available on all inputs and outputs, you'll find the HD MADI to be a very useful addition to any Pro Tools|HD studio. And the inclusion of both coaxial and optical I/O makes the HD MADI an easy fit. Features: 64-channel MADI interface Coax and optical connectors Cable lengths >1 mile with optical I/O Bidirectional sample rate conversion for input and output Easy integration into complex mixed sample rate environments Supports Varispeed mode (56 channels) Send and receive up to 64 audio streams between Pro Tools|HD and other MADI devices Maintain maximum audio fidelity, with up to 24-bit/192kHz sample rate support Gain connection and routing flexibility through optical and coaxial connections: 2 MADI inputs (optical and coaxial), 2 MADI outputs (simultaneous optical and coaxial) Built-in SRC on all I/O channels Completely integrates with Pro Tools|HD for full input, output, and routing control Sync to an external clock through dedicated BNC Word Clock and XLR AES/EBU connections when using SRC on output Keep things in sync with versatile clock support, including Internal, Loop Sync, Word Clock, AES/EBU, and MADI Gain better device compatibility with 64-channel (non-Varispeed) and 56-channel (Varispeed) support (at 48kHz) Integrate Pro Tools|HD with MADI-equipped VENUE live sound systems for recording and Virtual Soundcheck Verify and troubleshoot signals through status indicators and global I/O signal LEDs Compact 1U rackmountable design overcomes space limitations Connects to Pro Tools|HD through 2 DigiLink Mini connections (32 audio channels each; cables and adapters included)
