Port Sharing
Input and output port protection works
as normal when dealing with Hydra2
Patchbays for both console and H2O
users. In situations when two or more
consoles are using the same feed from
a Hydra2 Patchbay (as shown in Fig 2)
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
Hydra2 Patchbay input, either through
a Memory load, or through changing the
individual patch.
In these circumstances it is important that
the console operator understands the
contents of the Input/Output protection
dialogue before accepting any changes,
as these changes directly affect other
network users.
Console operators are given the
ability to change the source feeding a
HPB that is feeding other consoles to
add increased flexibility. However we
advise that all I/O box port to Hydra2
Patchbay input patching is controlled
from H2O or a third party controller
to avoid unwanted changes to other
console’s source feeds.
Unpatching
Under normal circumstances when I/O
box ports are unpatched, their input
settings (Mix Gain, SRC. 48V) are reset
to their default values. However, when
using Hydra2 Patchbays it is possible to
unpatch a port at two points in the signal
chain, as shown in Fig 3 on the right.
If the port is first unpatched at point
2, the I/O box port’s input settings will
be retained, even when the port is also
unpatched at point 1.
