Protect A Patch From Memory Loads; Isolating A Patch; Removing A Patch; Inputs 1 And 2 - Calrec SUMMA User Manual

Protect a Patch from Memory Loads

Patches can be 'fixed', isolating them from memory load changes. Fixed patches are also protected under the port
protection system in the same way as ports which are in use by multiple Hydra2 network users (See
Destination Protection" on page
To Fix a patch:
1. Select one or more patched destinations.
2. Tap FIX in the window footer.
3. To un-fix the patch, tap FIX again.

Isolating a Patch

Isolating a patch protects it from changes due to memory loads, but it differs from patch fixing in that patch isolation only
relates to actions performed on the local Summa console. Isolated patches can still be over-patched by other Hydra2
users and by memory loads on other consoles on the network.
To isolate a patch:
1. Select one or more patched destinations.
2. Tap ISO in the window footer.
3. To de-isolate the patch, tap ISO again.

Removing a Patch

To remove a patch from the system:
1. Select either the source or destination (or one of the destinations if the source is patched to more than one).
2. Tap REMOVE in the window footer. The patch is automatically removed, unless it is 'fixed' on the surface or
was made by another Hydra2 user, in which case a pop-up appears requiring confirmation of the removal .

Inputs 1 and 2

Every Summa channel has two inputs, 1 and 2, to which two entirely separate feeds can be patched. Input 2 is generally
used for patching a back-up microphone so that if the feed to input 1 fails, you can quickly switch to use input 2, which
has exactly the same processing, routing and output patching applied to it as input 1.

Patching Outputs to Inputs

Desk outputs and buses can be connected directly back into channel inputs. This method of control is different to just
attaching a console output to a fader. From the I/O patching screen select DESK OUTPUTS in the sources window
and DESK INPUTS in the destinations window and patch as normal.
