other slave-devices, which are to be connected to the master-device via a balanced microphone lead.
Connect the DMX OUT-jack with the DMX IN-plug of the next device.

Set the desired Master-mode for the master-device. Set the respective Slave-mode for all slave-devices.


If you wish to lock the light output - e.g. via an optional footswitch (Blackout-mode), connect your footswitch
via a mono-jack plug to the Blackout-socket.
