Port Sharing - Calrec SUMMA User Manual

FIGURE 1 - HYDRA PATCHBAY OPERATION

Port Sharing

Source and destination protection works as normal when dealing with HPBs for both console and H2O users. In
situations when two or more consoles are using the same feed from a HPB it is possible for one console to change the
patching of the other by changing the I/O box port which is feeding the shared Hydra patchbay input, either through a
memory load, or through changing the individual patch. In these circumstances it is important that you understand the
contents of the source and destination protection pop-up before accepting any changes, as these changes directly affect
other network users.
To create a fully flexible system, you can change the source feeding an HPB, which is also feeding other consoles.
However, we advise that all I/O box port to Hydra patchbay input patching is controlled from H2O or a third party
controller to avoid unwanted changes to other consoles' source feeds.
