The Paperwork Behind a Smooth Show: Run Sheets and Signal Diagrams

Most problems on a show day are not equipment faults. They are small disagreements about the plan: the camera operator believes the interview starts at the top of the hour, the sound engineer believes there is a music cue first, and lighting is waiting for a call that nobody was told to give. A written plan removes that guesswork before anyone touches a cable.

As a lighting designer I see this most clearly at the focus stage. When the run sheet says which sets are used in which order, I can focus the lamps for the first scene first and leave the later ones until the crew has a quiet moment. Without it, we spend the early hours lighting everything evenly and run short at the end.

In these mid-autumn weeks, with early dark and a run of evening events, the same habit pays off again. Load-in windows are shorter, venues are cold and tired crews make more mistakes, so the paper has to carry more of the thinking.

• A plan on paper settles disputes quickly
• Early cues can shape the order of focusing
• Short days leave less room for improvising

Our run sheets are built as a simple table. Each row is a moment in the show, with a start time, a duration, what happens on stage, and a short line for each department: vision, sound, lighting and any playback. We keep the wording plain enough that someone covering a shift can follow it without a briefing.

The most useful column is often the last one, where we note who calls the cue. It sounds trivial, yet it is the first thing to go missing when a show is passed between people. If a lighting change depends on the director's word, the sheet says so, and the lighting operator knows to watch for it rather than for the clock.

We number every row and print the sheet with generous margins. Crews write on it during rehearsal, and those pencilled corrections are fed back into a clean version the same evening, so the next day starts from one agreed copy.

• Time, duration, action and one line per department
• A named person for every cue
• Numbered rows, printed with room for notes

A signal flow diagram shows where each picture, sound and control signal starts, what it passes through and where it ends. For a studio, that might run from a camera head through a vision mixer to a recorder and a monitor wall. For a stage, it follows microphones through the desk to the speakers and the monitors.

We draw them for people who have to fix things, not for people who admire drawings. Every box carries the real label found on the equipment, and every line carries the cable type or connection standard. When a picture goes black ten minutes before transmission, the technician can trace the chain with a finger and find the break in a minute or two.

Lighting has its own version of this. Our dimmer and data lines are drawn the same way, so a fault in a lighting circuit can be traced as quickly as a faulty video feed, and the two diagrams share a page when the venue is small.

• Real equipment labels on every box
• Cable type or connection noted on each line
• Lighting data drawn in the same style

Handover notes are the part clients often skip, and the part they later thank us for. They are a short document, usually two pages, that records how the system was left: which inputs are patched where, what the default settings are, which cues are stored and what we would check first if something behaves oddly.

They matter most when the crew changes. A studio might be run by one team for a launch and by a different group a month later. Instead of relying on memory, the new team reads the notes, runs through the checks and starts from the same point we finished.

I write the lighting section myself, listing the preset names, the colour temperature we settled on for presenters and any lamps that were moved from the original plot. If a bulb is replaced or a lamp repositioned afterwards, the notes tell the next person what the intended picture looked like.

• Where inputs and outputs are patched
• Stored cues and default settings
• What to check first when something misbehaves

A plan that is never updated is worse than none, because people trust it. We therefore give every document a version number and a date in the corner, and we print only the latest version on show day. Older copies are collected at the end of each rehearsal so nobody works from a retired sheet.

Changes are agreed in one place. If the producer moves a segment, the run sheet is corrected first and the rest of the paperwork follows. We then tell each department what changed on their row, rather than announcing it to the room, because a general announcement is the easiest thing to forget.

After the event, we compare the plan with what actually happened and mark the differences. Those notes go into the next project, so the templates improve slowly and honestly, based on real shows rather than on how we hoped they would run.

• Version number and date on every page
• One agreed place for changes
• A short review once the show is over

The quality of our paperwork depends on what we learn early. The most helpful thing a producer can send is a draft running order, even a rough one, together with the names of anyone who will be speaking or performing and a note of any fixed transmission or doors time.

It also helps to tell us who will operate the system afterwards. A set of notes written for a trained technician looks different from one written for a volunteer team, and we would rather write for the right reader from the start than simplify it later.

Finally, let us see the venue or studio, in person or through photographs of the power, rigging points and cable routes. Lighting in particular depends on ceiling heights and available positions, and a diagram drawn without that information tends to need redrawing on the day.

• A draft running order, however rough
• Names of presenters or performers
• Photographs of the room, rigging points and power
