I/O BOXES & HYDRA PATCHBAYS SAMPLE RATE SELECTION IN H2O
From Version 1.1 Brio36 C
onsoles can now work at 96kHz sampling frequency (sample rate).
There are 2 elements to 96kHz operation of Brio36 consoles:- Configuring the DSP and configuring the I/O to run at
different sample rates.
Consoles at 96kHz
The consoles can switch between 48kHz & 96kHz working as required and they switch their sampling frequency by
loading a show at the required sample rate built from a template at that rate. For Brio, the numbers of channels and buses
are the same at 96kHz as they are at 48kHz. There is no reduction in the numbers of monitor inputs & outputs at 96kHz.

I/O and Hydra2 Patchbays at 96kHz
Before the I/O can be used with a
96kHz console its sample rate has
to be changed to match. In H2O a
new button labelled “Sample Rate” is
made available, selecting this opens
the list of I/O boxes connected to the
Hydra2 Network.
The list shown in Figure 1 shows the
sample rate set for each I/O box or
Hydra2 Patchbay. In order to change
the sample rate the user first selects
the required I/O box or Hydra2
Patchbay box, this enables the Set
Sample Rate button at the bottom
left of the screen.
Clicking on this opens the
‘Set Sample Rate’ pop-up, allowing
the I/O boxes and Hydra2 Patchbays
to be set to 48kHz or 96kHz, or to
follow the sample rate of a specific
console. This is shown in Figure 2,
please note that certain older I/O
boxes cannot be set to run at 96kHz
such as the fixed format MADI box.
The Hydra2 network supports 48kHz
and 96kHz consoles and I/O boxes
simultaneously, it achieves this by
running 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.
