DSP mirroring function in the Dante audio network

If the active DSP engine fails over, the stand-by DSP engine will take over all I/O patches for the TWINLANe network, and the audio will continue without interruption. However, patches for the Dante audio network will not switch over automatically. So, you need to make settings so they will switch over. First, assign input patches to the Dante cards (HY144-D, HY144-D-SRC) that have been installed in the active DSP engine and the standby DSP engine. Also, make sure that the control IDs for the active DSP engine and standby DSP engine are unique, and specify the same With Recall setting on both DSP engines. Assign output patches from the Dante card (HY144-D, HY144-D-SRC, or Dante MY16-AUD card) that was installed on the RPio622/222. With these settings, audio input and output, and HA controls will be kept uninterrupted even if failover occurs. Meanwhile, you cannot set up Dante patches for the Dante card (HY144-D, HY144-D-SRC) installed on the standby DSP engine in advance. Therefore, you need to prepare a Dante Preset in advance, and you would need to manually switch to this preset in case of failover. Please note that HA controls are available only from a Dante card (HY144-D, HY144-D-SRC) inserted into the DSP engine.
