SYSTEM OVERVIEW
96KHZ OVERVIEW FOR BRIO 36
From version v1.1, Brio 36 can now also work at 96kHz sampling frequency (sample rate), over a Hydra2 Network.
The following list is a quick overview of the impact of running Brio36 consoles at 96kHz
• The consoles can switch between 48kHz & 96kHz working as required.
• Consoles switch sampling frequency by loading a show at the required sample rate built from a template at that rate.
• The numbers of channels and buses are the same on Brio 36 at 96kHz as at 48kHz, i.e. the same as before.
• There is no reduction in the numbers of monitor inputs and outputs at 96kHz.
• I/O boxes can be set to 48kHz or 96kHz, or to follow the sample rate of a specific console, via H2O.
• The Hydra2 network supports 48kHz and 96kHz consoles and I/O boxes simultaneously.
• 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.
• Because Hydra2 always runs at 48kHz, the system will still require a 48kHz sync (if using its AES3 & Wordclock
inputs) even if all consoles and I/O are at 96kHz.
• The console patching screens and required list indicate which ports, HPB, aliases, or boxes are at a different sample
rate to the desk. These ports etc. can be patched (except for System level patches) but will not work until the sample
rates are matched.
• The H2O patching screens filter the ports visible by sample rate, as it can make patches at either rate.
• Consoles cannot successfully make port to port patches (including via aliases) for I/O that is at a different sample rate
to the desk. Note: these patches can be made in H2O and by SW-P-08 and will work if patched there.
• System Status messages are produced for I/O boxes & HPB that are in the required list but are not set to the same
sample rate as the desk.
• An I/O box can run at 48kHz or 96kHz irrespective of which rack it is plugged into. If a console is running at 48kHz,
an I/O box plugged into that rack could be running at 96kHz with another console.
• Fixed format 1U MADI boxes do not support 96kHz. They are shown offline when the box is at 96kHz.
• SDI de-embedder modules do not support 96kHz on the SDI stream. They are shown offline if the box is at 96kHz.
• SDI embedder modules do not support 96kHz on the SDI stream. They are shown offline if the box is at 96kHz.
