How do I keep multiple laser units synchronised in large venues?
Direct answerUse professional controllers such as the Pangolin FB4 series over a stable network or DMX link, and complete offline pre-programming and preview before the on-site build.
The Three Elements of Stable Sync
Professional controllers
Network playback controllers give every fixture the same frame and timing reference.
Reliable transmission
Switched network with fibre or shielded cabling for long runs and high channel counts.
Offline pre-programming
Programming and preview finished before load-in, so site time goes to alignment only.
Commissioning Sequence for Large Rigs
- Assign fixed addresses and zones to every fixture before leaving the workshop
- Verify the network link end to end, then test each zone before the full rig
- Run the complete show once with all units live before rehearsals begin
- Record final settings so the configuration can be rebuilt quickly at the next venue
Multi-unit sync problems are usually network or addressing issues, so verify signal and addressing before touching the show programming.
