For bigger set, stage, or outdoor situation, you will need more than one smoke machine and mostly you would need to comand all the machines with only one "fired" button: the solution is to link the machines one to the other with the exclusive G300 Link Lead 5m. There is a "5 pin xlr" socket in the back of the machine, so you can plug the Link Cable directly from a machine to another. You will have to change the Switch Setting Option and set to "Flow Accept" and "Smoke Accept" the "slave" machine.
For G300 Smoke Machines; size: 5 m
