Operator Manual
Using H20
PortSharing
Input and output port protection works
as normal when dealing with Hydra
Patchbays for both console and H2O
users. In situations when two or more
consoles are using the same feed from
a Hydra Patchbay 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
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 Hydra
Patchbay input patching is controlled
from H2O or a third party controller
to avoid unwanted changes to other
consoles’ source feeds.
Un-patching
Under normal circumstances when I/O
box ports are un-patched, their input
settings (Mix Gain, SRC, 48 V) are reset
to their default values. However, when
using Hydra Patchbays it is possible to
un-patch a port at two points in the signal
chain, as shown in the figure on the right.
If the port is first un-patched at point 2,
the I/O box port’s input settings will be
retained, even when the port is also un-
patched at point 1.
