Horus User Manual
MADI 1
This MADI port (switchable between coaxial or optical input connections using the front panel Touch
Screen) provides users with up to 64 channels of MADI I/O for use with the system. The signal sent to
the MADI Outputs (both Coaxial and Optical are available simultaneously) are configurable in blocks of
8 channels and can be sourced from any other module in the Horus.
MADI 2 (Expansion Slot)
An expansion slot allows a second MADI card to be fitted into the Chassis, bringing the total MADI I/O
up to 128 channels. When using the RAVENNA connection to deliver sound to your Pyramix or Ovation
system, this increases the total possible Inputs and outputs in a single Pyramix/Horus combination to a
mind-boggling 176 x 178 channels (combined Analogue/AES/MADI).
AES-EBU
3 x D-SUB25 connectors providing 24 channels (12 AES pairs) of AES-EBU I/O are Included as
standard (as is the MADI 1 module).
Signal routing paradigm
Horus is quite possibly the most flexible audio interface ever designed. Users can literally route any
input signal to any output module. Better yet, it can route any input signal to any combination of output
modules. Routable in blocks of 8 channels, a user can send 8 Mic Inputs to 8 AES outputs. At the same
time these 8 mic inputs can also be sent via the MADI outputs and included in the RAVENNA stream.
RAVENNA IP Audio
Using RAVENNA IP audio, Horus can connect to a standard network, using off the shelf switches and
other IT technology to become a node on a LAN. From that point, any other RAVENNA node can
receive information from and deliver information to, any combination of RAVENNA devices on the
network. It is a revolution in Audio technology and will soon mean the end to costly audio routers and
matrices and allow any facility an immense amount of flexibility. From Broadcast and TV/Film post-
production, to music, live events, theatres, cruise ships and many more applications, the RAVENNA
Enabled Horus interface will reinvent how systems come together.
Synchronization and Control information
Audio is not the only information that can pass down the RAVENNA connection. Horus is able to send
sync and control information such as LTC/MIDI/RS-422 and GPIO down the same wire to and from the
Horus unit.
