Horus User Manual
INTRODUCTION TO HORUS
Modular by Design
Horus was designed to give its users an amazing amount of Audio I/O channels, over all the most
deployed formats, while offering an unprecedented level of quality in such a small form factor.
Providing as standard 64 channels of MADI and 24 channel of AES- EBU I/O, you may choose to add
up to 6 Analog I/O optional modules and one additional MADI extension module to bring the total
MADI capacity to 128 channels and thereby 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 176 inputs and 178 outputs @1FS There are indeed 2 more output channels than input
channels, considering the Stereo Headphone Monitoring.
Route Signal Anywhere
Horus has been designed so that any input can be routed to any amount of outputs as required… at
the same time. With comprehensive routing pages accessible both locally on the touchscreen and by
remote access using a standard web browser, Horus is your answer to signal flow management in
your studio.
Green Built
For environmentally-conscious users, Horus has been meticulously designed in order to keep
consumption at an incredible minimum. A fully loaded Horus running all channels of phantom power
will only draw about 60W, making it more affordable to run than your kitchen lights.

Ravenna
The Horus has been designed so that the MADI, AES and Analog modules can all feed into or sink
from the network over Ravenna streams, providing up to 176 channels of I/O@1FS over a single
CAT5e or CAT6 cable to any other Ravenna devices on the network.
The Ravenna connection on the Horus allows for not only audio, but also control and sync information
to flow through as well. Send Timecodes, Wordclock and even GPIO directly to the Horus unit over
the same network as your audio. The Ravenna port even provides for the remote control access to
the configuration and entire routing of the unit itself! Support for: RS-422/LTC/MIDI/GPIO/Video
Ref/WCK
Ravenna is a layer3 IP based protocol. In environments where existing networks are already in place,
Ravenna subnets can slip right into place with no additional outlay. In laymen’s terms, this means that
you can connect your Horus to a properly configured network exactly as you would do for your PC or
Mac, with no additional technology required.
Ravenna is a “mission critical” protocol, meaning that is has been designed to ensure immensely low
jitter rates and latencies (sub-millisecond) and reliably ensures that every single sample gets to where
it needs to go without fail. Horus also provides a secondary, redundant Ravenna connection allowing
for uninterrupted use, even when a network connection fails.
