Parameter mirroring
In parameter mirroring, only parameters are synchronized between two DSP engines, and you need to switch
the active DSP engine between DSP A and DSP B manually. Unlike TWINLANe mirroring, input and output
patches will not switch over automatically if DSP engines are switched between active and standby states.
So, you need to make settings so they will switch over. First, assign input patches from Dante devices such as
Rio3224-D2 to the Dante cards (HY144-D, HY144-DSRC) that have been installed in the active DSP engine and
standby DSP engine. Also, make sure that the Dante control IDs for the active DSP engine and standby DSP
engine are unique, and make the same With Recall setting on both DSP engines. With these settings, audio
inputs and HA controls will be kept uninterrupted even if the active DSP engine is switched. However, output
patches for both the active DSP engine and standby DSP engine cannot be assigned to the same outputs, so
they must be switched by using an external device. On the other hand, output signals from MY cards installed
in the control surface and OMNI OUT will switch over when the DSP engines are switched. So audio output
will not be interrupted when output patches from Dante cards (Dante MY16-AUD/AUD2 card) installed in an
MY slot are assigned even if the active DSP engine is changed. Choose either setting according to your
system. But, in either case, please do not turn off the DSP engine that was switched to the standby state. And
set either Dante card (HY144-D, HY144-D-SRC) installed in both active DSP engine and standby DSP engine to
the clock master. This will shorten the audio interruption period as the PTP master in the Dante network will
be taken over smoothly.
