HYDRA PATCHBAYS
Hydra patchbays (HPBs) allow console users to make selected DSP audio outputs available across the Hydra2
network, allowing other Hydra2 users to access them, as well as allowing console input sources and output feeds
to be changed remotely. Hydra patchbays are created from the H2O user interface. See the H2O user guide for
more information.
HPBs are virtual patchbays which exist within the Hydra2 domain. Like physical patchbays, HPBs have a number of input
ports which are ‘hard wired’ to their corresponding output ports. For port patching purposes, Hydra patchbay inputs are
destinations and Hydra patchbay outputs are sources.
When a source is patched to a Hydra patchbay input, it immediately becomes available at the corresponding Hydra
patchbay output. For example, if a console user patches a direct output to a Hydra patchbay input, the direct output is
available to all Hydra2 users (who have been granted access), in the form of the corresponding Hydra patchbay output.
Console Specific or Shared
There are two types of HPB: ‘console specific’ and ‘shared’. Console specific HPBs are available to H2O, 3rd party
controllers (via SW-P-08) as well as the console that they have been created for. Shared HPBs are available to all Hydra2
users who have been granted access as well as H2O and 3rd party controllers (via SW-P-08). You can patch signals to
your own, or shared Hydra patchbay inputs, in the same way as patching to physical output ports.
Remote Patching
HPBs allow network administrators (via H2O) to patch console inputs and outputs that have been patched to HPB
ports to physical I/O ports. H2O users can choose physical input ports to connect to console HPB inputs, and
physical output ports to connect to console HPB outputs, allowing them to choose and change console feeds and output
destinations.
External routers, supporting the SW-P-08 protocol, can also access HPBs, enabling 3rd party control over console
patching. Once created, HPBs can be made available for patching. They appear ‘online’ and can be added to the
console’s ‘required list’. See
“Editing The Network” on page 62 for more information.
