Merging Technologies IOC-HORUS Converter

What is Merging Technologies IOC-HORUS Converter  ? Horus might be one of the worlds most sonically transparent mic pres. Horus might also be one of the most phenomenal AD/DA boxes on the market. Horus could very well be the ultimate answer to anyone wanting analog/AES/MADI interconnectivity in the room they work in. Merging Technologies IOC-HORUS Converter is a revolution in bang-for-buck technology and is set to become the de-facto audio I/O device for the media industries.

But, in reality the Merging Technologies IOC-HORUS Converter is much, much more. Using Ravenna technology, Horus brings to the table the possibility to interconnect your entire facility using nothing more than a standard RJ45 connector. Once in Ravenna mode, the Horus box simply becomes a node on a network, one that can be instantly called to be an input, an output, or a combination of both.

Using standard network connections, switches and connectors, Horus and other Ravenna-enabled devices can be placed on a network and interconnected in any way you can imagine.

Standard Connections:

• 64 MADI I/O (Optical or Coaxial)
• 24 AES/EBU I/O (on DSub 25)
• RAVENNA I/O (on RJ45)
• SYNC – LTC/MTC/VideoRef/Wck (requires CON-D15-VTC cable)
• 6 option slots for AD8D/AD8DP and DA8/DA8P cards
• 1 option slot for MADI expansion option

Optional Additions:

• AD8D and AD8DP standard and premium Mic/Line Input cards
• DA8 and DA8P standard and premium Line Output cards
• MADI expansion card delivering 64 additional MADI channels
• Redundant power supply option
• RS-422 and GPIO option card (In Development)

The ability to choose the amount of I/O that each Merging Technologies IOC-HORUS Converter unit is capable of saves money without diminishing the level of quality. Choose to add any of the option modules to your Horus and create the ultimate audio interface for your studio, whatever the size. Once the Horus is fully loaded with option cards, it is capable of achieving an astonishing, simultaneous 176 inputs and 178 outputs @1FS.

Features:

• Up to 24 world-class mic preamps in a 2u chassis
• Remote-controllable gain over Ethernet
