# A preset is a memory, not a setting

> Eight rotary controls on a preset panel record a full state for the room under one number each, so a whole look can be recalled with one movement instead of eight separate ones.

Eight rotary controls in a row, each turned to a different position, each pointer readable at a
glance. Underneath them, stencilled small: PRESET 1 through PRESET 8.

Nobody is touching these knobs during the show. That's the entire point of having them.

## What is a preset panel actually recording?

A full state for the room — every light at whatever level makes up one particular look — captured
under a single number so it can be brought back with one movement instead of eight.

Older lighting desks built this out of physical hardware: a bank of rotary faders, one per preset,
each one set to a level before the show and left alone once it's right. Pressing that preset up
brings the whole room to that state at once, whatever it was doing a second before. It isn't
adjusting the lights. It's recalling a decision that was already made, the same way [only a
fraction of a dimmer rack's forty-eight channels are ever live for one particular
scene](/stories/dimmer-rack-channels) rather than the whole rack moving at once.

## Why does having eight fixed positions matter more than being able to adjust live?

Because most of what a show actually needs isn't a new look invented in the moment — it's the exact
same eight looks, reliably, on the exact same cue, every single performance.

House lights up before doors, house lights down at the top of the show, a warmer wash for the
interval, the state the stage sits in before anyone's walked on — a handful of states cover most of
what a room needs, and getting the same one back exactly is worth more than the ability to
improvise a new one. Fixed positions are a promise that number three tonight is number three
tomorrow.

## What makes a good drawing of a panel like this?

Letting all eight knobs point somewhere different, rather than lining them up as if they were
decoration.

A row of identical knobs at an identical angle reads as a pattern, not as a control panel — nothing
about it says any decision was actually made. Genuinely varied pointer positions are what make the
eight read as eight separate, deliberate choices rather than eight repeats of the same shape.

## Who owns the idea of a numbered preset system?

Nobody. Assigning numbers to a set of saved states is a general idea used across control equipment
of every kind, not any one manufacturer's invention.

What belongs to somebody is a specific desk's own casing, badge and control layout, if a real
manufacturer's board is the point of the shirt — licensable the ordinary way. Left as a generic row
of knobs and plain numbers, the drawing describes the concept rather than copying anyone's actual
product, the same distinction as [a gel's colour belonging to nobody, though the numbering system
printed on it belongs to whoever prints the book](/stories/lighting-gel-swatch-book).

## Does the idea of a preset only belong in a theatre?

Any place that runs the same handful of states night after night has a version of this, whether or
not it's built into physical knobs.

A restaurant with a lighting scene for lunch and another for dinner service, a house of worship
running the same look for a service every week — the theatre version is just the one where the
positions are readable at a glance by someone standing across the room, because they're physical
rather than buried in a menu on a screen.

## Isn't eight fixed looks a limited way to run a show compared to full live control?

Only if reliability counts as a limitation, and to the people running the room it counts as the
whole job done well.

A show that needs a genuinely new state built live still has channels free to do that — presets
don't replace a desk, they take the repeatable ninety per cent off it so a person's attention is
free for whatever's actually live that night, the same way [a running order takes the fixed part of
an evening off anyone's memory so the unpredictable part gets the attention](/stories/backstage-running-order-board).

## Does it print well?

Yes — eight simple dial shapes at eight different angles are exactly the kind of repeated,
readable form that holds up well at print size.

Amber for the pointers keeps them the first thing the eye finds against the row of knob bodies;
cream carries the dial outlines and the stencilled labels. Keep the stencil breaks in PRESET 1
through PRESET 8 genuinely open rather than closing them up for legibility — a bridged stencil
letter reads as a mistake, not as the real thing.

## How do I get one made?

Describe the panel at [JustOG](/) — how many presets, which positions the pointers should sit at,
and what to call each one. Pick a direction, drag the crop frame, see it composited on the real
garment, and it's made to order and shipped.

Designs other people have published are in the [shop](/shop).

Eight knobs, eight positions, and none of them moving during the show.
