Lighting control for stages, events and installations
This department covers the equipment used to operate, distribute and manage control signals for professional lighting fixtures. Options range from compact manual controllers for simple rigs to software-based control, multi-universe systems, wireless DMX and architectural wall controls.
The right solution depends on the number and type of fixtures, required DMX channels, number of universes, programming method, control location and whether the system is temporary, touring or permanently installed.
Choosing a DMX lighting controller
DMX controllers include compact fader desks, dedicated hardware controllers, computer interfaces and architectural control systems. Some are designed for straightforward colour and scene control, while others support moving heads, programmed sequences, multiple universes or software-based show operation.
- Manual fader controllers suit smaller rigs where direct access to intensity, colour or simple fixture channels is required.
- Programmable hardware controllers provide stored scenes, chases and fixture control without requiring a computer during operation.
- Software and USB interfaces use compatible computer software for programming and playback.
- Architectural controllers provide stored scenes and simplified user operation for venues, hospitality and installed lighting systems.
Check fixture personalities and channel modes before choosing a controller. A single fixture may use several DMX channels, so the fixture count alone does not indicate the required controller capacity.
What is a DMX universe?
A DMX universe carries up to 512 control channels. Each fixture is assigned a starting address and occupies a block of channels determined by its selected operating mode. Larger or more detailed systems may require multiple universes, suitable outputs and a controller capable of managing them.
DMX normally controls lighting and effects rather than supplying their operating power. Fixtures still require appropriate mains power and power distribution alongside the control network.
DMX splitters, nodes and signal processing
DMX signal-processing equipment includes distribution splitters, boosters, network nodes and related interfaces. Splitters divide a control signal into separate branches, helping to create practical cable routes and isolate sections of a larger lighting system.
Network nodes convert compatible Ethernet lighting protocols to or from physical DMX outputs. When selecting signal-processing equipment, check the number of inputs and outputs, supported protocols, universe capacity, connector format and whether RDM pass-through is required.
Wireless DMX lighting control
Wireless DMX can replace selected sections of control cable where running a wired connection is impractical. The range includes transmitters, receivers, transceivers, bridges, antennas and fixture-specific upgrade components.
A wireless link does not automatically make every fixture remotely controllable. A compatible transmitter and receiver system is required, and products from different wireless ecosystems may not communicate with one another. Check protocol compatibility, operating frequency, permitted range, antenna requirements and the conditions of the venue before specifying a system.
Wireless DMX can simplify particular cable routes, but critical systems should still be planned around interference, signal coverage and a suitable contingency method.
Dimmers and switch packs
Dimmer and switch packs provide controlled power outputs for compatible lamps and equipment. Dimming changes the supplied waveform and must only be used with loads specifically designed for that type of control. Switching provides on-and-off control for suitable equipment without intentional intensity adjustment.
Do not connect LED fixtures, moving lights, power supplies or other electronic equipment to a dimmed output unless the manufacturer explicitly permits it. Check load type, total current, channel rating, connector format and control method before use.
Wall plates and fixture remotes
DMX wall plates provide accessible control, network or playback points for compatible installed lighting systems. Confirm the required back box, cabling, controller and system compatibility when planning an installation.
Handheld and infrared remotes provide convenient access to selected standalone fixture functions. These remotes are generally product- or range-specific, so compatibility should be confirmed against the exact fixture model.
What else is needed for a DMX system?
- A controller with enough channels or universes for the selected fixture modes.
- Properly specified DMX cables with compatible 3-pin or 5-pin connections.
- Correct fixture addressing and a documented DMX patch.
- Signal splitters or nodes where the system branches or spans multiple universes.
- A suitable terminator at the end of each applicable wired DMX line.
- Separate, correctly rated power distribution for the connected fixtures.
