CALREC Putting Sound in the Picture 31
Output port protection is a system
that notifies users when they are
attempting to patch to outputs that
are already in use and provides
information to assist in deciding
whether to go ahead with each over-
patch individually, or as a group.
All output destinations are available to
all users across the Hydra2 network if
permitted within H2O, but only one audio
feed can be routed to each individual
output at any one time. When an output is
in use, it is “protected” from over-patching
by other users.
Patching to a Protected Output
When patching a source to a protected
destination, a pop-up appears on the PC
screen containing a table of information
to help decide whether to accept the
patching change. When executing a salvo
(see “Salvos” on page 32) it is possible
that there will be more than one patching
conflict. In such cases the table will have
several rows. From H2O it is also possible
to un-patch ports from desk connections.
Note that H2O un-patches are not held
in console hidden memory and so if the
console is rebooted, or the user memory is
reloaded, these patches will be re-made.
The pop-up functions in the same way
whether it results from a single patch, an
un-patch or a salvo-load.
From left to right the pop-up displays
the source you are attempting to patch,
the source that is currently patched to
the protected output, the label of the
protected output and the name of the
console that is protecting the output.
The check boxes down the left hand side
allow you to select or deselect patching
changes individually. SELECT ALL selects
and deselects all patching changes in the
list together.
PORT PROTECTION POP-UP - H2O
Once you are happy with your selections,
ACCEPT CHANGES executes all
selected patching changes in the list.
CANCEL ALL cancels all patching to
protected output ports.
