How to choose a stage

Stage decks

From your first floor plan to a system that fits the venue and performance.

Essentials

What kg/m² actually means

Stage decks

Understand the difference between a distributed load and a heavy object at one point.

A closer look

Straight or curved choir risers

Choir & orchestra

A layout starts with sightlines to the conductor and ends with usable access.

Essentials

Orchestra: chairs, stands and conductor

Choir & orchestra

A useful layout leaves room for playing, reading music and moving.

Essentials

Truss: span, supports and loads

Truss & rigging

A single capacity figure cannot describe an entire structure.

A closer look

D8, D8+ and C1 explained

Truss & rigging

A hoist class describes capabilities; assessment covers the complete system.

A closer look

Stand or lifting tower?

Stands & towers

Consider the load, reach and space needed for stable operation.

Essentials

What to check before lifting

Stands & towers

Learn to identify the documents and components that need attention.

A closer look

Choose a barrier for its role

Barriers & crowds

Queue guidance and resisting crowd pressure are different tasks.

Essentials

Screens, lecterns and AV stands

Event & AV equipment

The practical measurements you need before selecting equipment.

Essentials

Audio and DMX: similar plugs, different jobs

Cables & connectors

The connector is only the beginning of a compatibility check.

Essentials

powerCON and TRUE1: check the exact model

Cables & connectors

Housing colour is not enough to make a safe decision.

A closer look

etherCON and network cables

Cables & connectors

A rugged housing protects the connection; the whole link determines network performance.

Essentials

Cable protection for the actual traffic

Cable protection

Channel count, clearance and crossing conditions matter more than tonnage alone.

Essentials

Plan the crossing, not just cable protection

Cable protection

Pedestrians, wheelchairs and service vehicles use a space differently.

Essentials

Wash, spot, profile and beam

Stage lighting

Start with what the light needs to do.

Essentials

Beam angle, lumens and lux

Stage lighting

Change distance and angle to see how coverage changes.

A closer look

DMX: an address is not a fixture number

Stage lighting

Learn to assign addresses without overlap.

Essentials

From a DMX line to an Art-Net network

Stage lighting

Separate the signal, transport network and physical connector.

A closer look

Kelvin is not colour quality

Architectural lighting

Distinguish white-light tone, colour rendering and camera behaviour.

Essentials

DALI: lighting with scenes

Architectural lighting

Addressing, groups and control in a permanent installation.

A closer look

A laser show starts with safety

Lasers & atmosphere

What an organiser needs to understand before choosing effects.

Essentials

FB4, QuickShow and BEYOND

Lasers & atmosphere

Separate content creation from playback control.

A closer look

Fog, haze and the right fluid

Lasers & atmosphere

Atmosphere shapes how light is seen, but needs a venue plan.

Essentials

From the basics to the whole picture

Three suggested paths. Start where it suits you.

Small tools. Clearer decisions

Change a value and immediately see what it means.

Change the angle. See the difference

A geometric model of a circular beam perpendicular to a flat surface.

Diameter = 2 × distance × tan(angle/2). Does not calculate lux, uniformity or laser safety.

2.68 midealised diameter

Check your understanding

A fixture uses 8 channels starting at 9. Where does it end?
Does kg/m² give the permitted mass on one castor?
At the same angle, we double the distance. Idealised beam diameter…

Technology, in plain language

Short explanations lead to the wider context.

UDL

Uniformly distributed load. Read it with the correct span and supports.

Read in context →
kg/m²

Mass per area under declared loading conditions; not automatically a point-load rating.

Read in context →
DMX512

A digital link for stage-lighting control channels.

Read in context →
Universe

A group of 512 DMX channels.

Read in context →
Footprint

The consecutive channels used by a selected fixture mode.

Read in context →
RDM

Two-way communication for configuring and reading compatible DMX devices.

Read in context →
Art-Net

A protocol carrying lighting data over Ethernet.

Read in context →
sACN

A network protocol carrying lighting control data.

Read in context →
Lux

Illuminance on a surface. Compare at matching distances and optics.

Read in context →
Lumen

A unit of luminous flux, distinct from lux.

Read in context →
CCT

Correlated colour temperature, expressed in kelvin.

Read in context →
TLCI

A colour-rendering assessment for a television chain using EBU methodology.

Read in context →
DALI

Digital lighting control, often used in permanent installations.

Read in context →
DT8

A DALI device type for colour control; not a version called DALI-8.

Read in context →
etherCON

A rugged locking RJ45 connector system.

Read in context →
speakON

A connector system for loudspeaker links, not mains power.

Read in context →
D8+

A hoist class for holding overhead loads under suitable system conditions.

Read in context →
FB4

Hardware for laser-content control and playback.

Read in context →
Haze

A fine atmosphere that can reveal light beams.

Read in context →
VESA

A mounting pattern to check against the screen, mount and their limits.

Read in context →

Good questions to start with

Is the test load the working capacity?

No. Use the declared working rating and manufacturer conditions.

Read the explanation and sources →
Is the winch rating the tower capacity?

No. The complete tower’s declared capacity governs.

Read the explanation and sources →
Can every powerCON be disconnected under load?

No. Check the exact model’s breaking capacity and operating instructions.

Read the explanation and sources →
Can two fixtures share an address?

They can receive the same channels, but matching-mode fixtures then lack independent control.

Read the explanation and sources →
Are all low-profile ramps accessible?

No. The complete geometry and crossing conditions need assessment.

Read the explanation and sources →
Is cooler light always brighter?

No. CCT does not measure flux or illuminance.

Read the explanation and sources →
Are DMX and DALI interchangeable?

No. Protocols and applications differ; integration requires a suitable system or gateway.

Read the explanation and sources →
Does an E-stop make the whole show safe?

No. It is one measure in a complete safety system.

Knowledge with traceable sources

These guides are editorial summaries of manufacturer and specialist documentation. Each article includes sources and a check date. Examples explain principles; model-specific instructions and qualified assessment determine application.
