Fireworks are often combined with lighting, video projection and laser effects, in addition to music and narrative, to create a total multimedia event.To synchronise all the elements within a multimedia experience, digital timecode is used as the reference from which all of the show cues are initiated.

Merlin have their own multi track recorders that allow digital timecode tracks to be layed down and perfectly aligned with audio and narrative tracks.

Where large displays are to be fired from many locations timecode can be broadcast by secure radio to enable them all to be synchronised over a very wide area.

This technology has permitted Merlin to fire displays that are choreographed to soundtracks broadcast by FM radio stations and shown live on television.
