Getting Signals into Apollo80 APOLLO Digital Broadcast Production ConsoleHYDRA2 PATCHBAYSHydra2 patchbays (HPBs) allowconsole operators to make selectedDSP audio outputs available onthe Hydra2 network, allowing otherHydra2 users to access them as wellas allowing console input sources andoutput feeds to be changed remotely.HPBs are virtual patchbays within theHydra2 domain. Like physical patchbays,HPBs have a number of input ports whichare ‘hard wired’ to output ports.For port patching purposes, Hydra2Patchbay inputs are destinations andHydra2 Patchbay outputs are sources,see Fig 1.When a source is patched to a Hydra2Patchbay input, it immediately becomesavailable at the corresponding Hydra2Patchbay output.For example, if a console operatorpatches a direct output to a Hydra2Patchbay input, the direct output feedbecomes available to all Hydra2 users(who have been granted access,) as thecorresponding Hydra2 Patchbay’s output.There are two types of HPB: ‘consolespecific’ and ‘shared’. Console specificHydra2 Patchbays are available to theconsole that they have been created for,plus H2O and 3rd party controllers viaSW-P-08.Shared Hydra2 Patchbays are availableto all Hydra2 users who have beengranted access, plus H2O and 3rd partycontrollers via SW-P-08.Consoles can patch signals to their ownor shared Hydra2 Patchbay inputs in thesame way they patch to physical outputports.Hydra2 Patchbays allow networkadministrators (via H2O) to patch consoleinputs and outputs (which have beenpatched to Hydra2 Patchbay ports) tophysical I/O ports.H2O users can choose physical inputports to connect to console’s Hydra2Patchbay inputs, and physical outputports to connect to console’s Hydra2Patchbay outputs allowing them to chooseand change console feeds and outputdestinations.External routers supporting the SW-P-08protocol can also have access to Hydra2patchbays enabling 3rd party control overconsole patching.Hydra2 patchbays are created from theH2O user interface. See the H2O userguide for more information.FIG 1 - HYDRA2 PATCHBAYSHPBs and different sample ratesFrom version 8.0 Hydra2 patchbays canbe configured to operate at 48kHz, 96kHzor follow the sample rate of a particularconsole when it loads a show. See “I/OBoxes & Hydra Patchbays Sample RateSelection in H2O” on page 54A Hydra2 Patchbay set to a different ratethan the desk will behave in the same wayas ports at different sample rates to thedesk. See the H2O user guide for moreinformation.Once created, Hydra2 patchbays areavailable for patching, they appear ‘online’in the >Hydra2 Settings>Edit Networkscreen of main application from wherethey can be added to the console’sRequired List for use in port patching.
