Audio Production System with Optional Networking
SETTING UP
SYNCHRONISATION
General rules of good practise require that all equipment connected to the audio console’s digital inputs and
outputs are locked to the same referenced sync source as the console to ensure clean audio.
In systems with multiple Calrec processing cores connected together, it is of paramount importance that all connected
processing cores are locked to the same referenced sync source.
The Brio 36 processing engine has six synchronisation inputs and six levels of synchronisation source priority. The sixth
priority is always set to ‘internal reference’, so that, as a last resort, if all other sync sources fail, Brio can always run off its
own internal clock. If a clock source does fail, Brio will automatically jump down to the next sync source in the priority list.
One is the highest priority, six is the lowest.
Setting Synchronisation Source Priorities:
• Tap SYSTEM SETTINGS in the top right of the touch display and select ‘synchronisation’ from the menu.
• Tap the selection cell for the sync priority level that you wish to alter. A pop-up appears with a scrolling menu of
possible sync sources. (The following figure shows the pop-up when selecting sync source priority 1).
• Tap to make your selection, scrolling down if necessary.
• The pop-up closes and Brio refreshes and syncs to the highest priority viable source.
Synchronisation at different sample rates:
Hydra2 runs at 48kHz irrespective of whether the consoles and I/O boxes are running at 96kHz or not. It simply uses 2
samples per 96kHz signal.
Hydra2 always runs at 48kHz, the system will still require a 48kHz sync if using its AES3 or Wordclock inputs even, if all
consoles and I/O are operating at 96kHz.
In ‘active Show’ view, the current sync source is always displayed
within the notifications area at the top right of the touch display.
