At large-scale events, redundancy is key—setting up backup confetti machines ensures the show goes on even if something fails. Place secondary machines in strategic locations, ideally mirroring the primary ones for balanced effects. Connect backups to a separate power source or circuit, and test them pre-show. Use DMX or manual controls that allow instant activation if a primary unit fails. Inform your tech crew of the contingency plan. While it adds a layer of complexity, having backup machines provides peace of mind and protects the event’s visual impact, especially during one-time moments like finales or key reveals.
