About DSP mirroring
The system can be configured with two DSP engines as a set, providing resilience against unexpected
software failures or hardware malfunctions that would not be addressed by the redundant power supplies of
the units or by TWINLANe cable redundancy.
There are two types of DSP mirroring: TWINLANe MIRRORING configured in the TWINLANe network and
PARAMETER MIRRORING configured in the Dante audio network.
Requirements for mirroring
(
The two DSP engine units are of the same model
(
The two DSP engine units have the same version
(
The Unit IDs of the two DSP engines are set to A and B of the same number (example: 1A, 1B)
(
The two DSP engine units are set to the same Unit Mode
(
The two DSP engine units have the same card configuration (Mini-YGDAI cards, HY cards)
The following conditions are also required only for TWINLANe MIRRORING.
(
The TWINLANe networks of the two DSP engine units have the same ring connection settings (MAIN and
SUB)
(
The connected RPio has the same configuration (version, Unit ID, etc.)

The parameters are periodically synced from the active DSP
engine to the standby DSP engine.
