Putting Sound in the Picture
101
the above diagram shows 4 control
rooms, each with a Calrec digital
console. once powered, the hydra
I/o racks broadcast “heartbeats” to
advertise their presence.
The Gigabit interface unit for each
console transmits and receives audio data
to and from the Hydra I/O Racks, via a
Gigabit switch.
Local I/O in the console’s own racks
can be used for connections to routers,
monitoring, talkback, inserts, etc. It is not
networked to the other consoles.
Synchronisation
Consoles sharing sources must be
synchronised (e.g. to station sync or
video). The Hydra I/O Racks synchronise
to one of the consoles via the network.

Network Exclusivity
In order to guarantee fully deterministic
performance, it is necessary to apply the
restriction that the network must be kept
private. This means that it must not be
made to carry any data other than that
generated by the audio network.
Network Editor
For a network to be truly useful, it must be
easy to use and maintain. The system’s
control software constantly monitors
the network, performing essential
administration functions, leaving the
user free to creatively exploit network
resources as easily as if they were locally
connected.
The Network Editor consists of a set of
screens for :
Configuration of Hydra I/O Racks •
Offline editing of Hydra I/O and •
Audio Network
Graphical representation of the
•
devices on the network
Utility for forcing ownership to be •
dropped
The Network Editor can be run
independently of the console via the
Offline Editor. This allows the modular
Hydra I/O boxes and audio network to
be configured off-line. Any operations
which require a console however are
disabled.
