In case you need a lot of smoke, fog, you will have to use more than one smoke machine: Le Maitre has developed a link system that allows you to link a G300 Smoke Machine to another using the exclusive G300 Link Lead 15m. The lead is a "5 pin xlr" and you can plug it directly to the back of the machines. You will have to change the Switch Setting Option and set to "Flow Accept" and "Smoke Accept" the "slave" machine.
