This launcher allows you to remotely fire any of our electric confetti cannons with a DMX controller or lighting console (not included), individually or up to 4 at a time! It features an adjustable launch angle for each side, assignable DMX channel, and a continuity light to confirm that your cannons are ready to fire. Each channel has its own DMX address. You just set the address for the first one, and the rest increment from there. So if you set "001" for the unit, then the 4 channels are 1, 2, 3, and 4. It uses a standard Edison power cable. It's perfect for DJs, churches, and theaters who want to add confetti to their productions!
