Array Setup
You can configure a longer array by stacking multiple modules and connect the modules by an expansion
cable. Up to a 3-module array is supported. The end connectors of an expansion cable are RJ-50 (cable
supplied), which is dierent from the RJ-45 for Control/Dante® (Ethernet), although they look similar. Take
notice when setting up a multi-module array.
For a multi-module array, the Ethernet cable has to be inserted to the receptacle located at the end of
the array, and the module in which the Ethernet cable is inserted becomes the Master module of the array
automatically. Audio signal and control signal are passed to the slave module(s) via the RJ-50 expansion
cable between the modules. You cannot insert the Ethernet cable into the modules other than the one
mentioned above. The array does not work when you insert the Ethernet cable into the wrong modules.
The master module represents the entire array; the IP address of the master module applies to the entire
array. i.e. a multi-module array can be seen as a single device; it is just a long array with more drivers than a
single-module array.
