Prism Sound MDIO-PTHDX Pro Tools HDX Card for Titan or Atlas

The Pro Tools MDIO-HDX module allows multiple Titan or Atlas units to be connected directly to an AVID Pro Tools HDX or HD native system via AVID's "Digilink" connection. With this setup, Pro Tools users can enjoy the excellent sound quality of both the Titan and Atlas A/D and D/A converters, and their equally well regarded on-board microphone preamplifiers. 

The first (or only) unit in the stack is connected to Pro Tools using its Primary connector. Additional units, to a maximum stack size of four units, are added by daisy-chaining Expansion-to-Primary connections in the usual way. Multiple stacks can be connected to multiple host Digilink ports to build systems with larger numbers of channels.

The following Pro Tools UI controls are supported: 

• Sample rate and Loop Sync slave/master selection (including master sync source)
• Interface 'identify' - helps find the right unit in a stack
• Line input sensitivity switching, per input channel (+4/-10)
• I/O port routing (as controlled in the Pro Tools Setup\Hardware dialogue) including use of enclosure S/PDIF/AES3 I/O. Routing to Titan and Atlas headphone port.
• Soft-clip (Prism Sound "Overkiller") switching, per input channel
• High-pass filter selection, per input channel
• Phase switching, per input channel
• Indication of mic/line/DI(instrument) input selection* (auto selecting on the Titan or Atlas unit, indicated in Pro Tools UI).
• Mic/instrument gain setting*
• +48V phantom power switching*
• -20dB pad switching*
