It is possible connect one AR2412 and via expander other AR2412. It is more interesting de ar2412 that AB168, because the price it is very similar and if it I have more inputs and outputs in the equipments.
For the moment this config don’t work… any ideas ???
Keep in mind you can also add the AR84 at the desk expander output and run that down to the stage for 8×4 more I/O channels. With an AR2412+AB168+AR84, and the surface connections, the GLD’s will actually support up to 56 *available* inputs even though you can only *assign* a max of 48 to channels.
