What is DMX Lighting? Rethinking How We Do Illumination

Whether you are running a multimillion-dollar stage production or just starting out on your DJ career, you have probably come across DMX lighting.

DMX lighting is a technology that has been in use for decades, but not many people really know what it does. It can be used to control and synchronize the color of lights, the intensity of light at different points on a stage, or anything else you could think of.

However, DMX lighting comes with a high price tag and complicated setup process - which can be challenging for an inexperienced user to navigate. This blog post will go into detail about how DMX lighting works and why we might need something better!

What is DMX 512?

Before we look at the alternatives to DMX lighting, it is helpful to refamiliarize yourself with DMX itself. DMX is an acronym for "digital multiplex," and DMX lighting uses a system of cables to connect light fixtures.

Each cable has two conductors (sometimes, but not always), which can be used as input or output signals. Inputs are sent from the controller - like a computer or other device - to the lights in order to control the lights. Outputs are sent from the light to the connector on a lighting console.

If you were using DMX-512, each signal would contain 512 possible values mapped to specific colors or intensities of light. The signals could be transmitted at rates between 125 and 250 kilobits per second - giving off an update rate of 20 to 30 frames per second.

The DMX Protocol

DMX lighting can be used for several purposes, such as controlling the color or intensity of lights at different points on stage, but it is not limited in this way. You can use DMX lighting anywhere you want and with whatever kind of light fixture you prefer - including moving lights, LED screens, lasers, and more.

DMX is a protocol that functions as both an input and output - meaning it can be used to control the color of light on a stage or from afar. DMX ultimately relies on the "master-slave" relationship for any system to function correctly. The controller will act as the master, and the lights will be slaves.

What is an Address?

An address is another name for a DMX channel. 

A "controller" assigns a number to an individual light fixture, corresponding with the first position in its sequence or "scene." This means that each time you add another light on stage and assign it to DMX lighting, it would take up one more of those channels - making them much harder to come by.

DMX lighting is not limited to one controller, either. You can have many controllers in a single system that all communicate together through the DMX data cable - but this adds complexity and cost when setting up your light show!

What is a Channel Group?

A channel group, or "channel strip" as it's sometimes called, includes channels that share similar attributes.

For example: if you're running three 600W red lights in separate fixtures on stage but want to control them all the same way and with the same commands from your DMX lighting console, they would be in the same channel group.

What is a DMX Universe?

DMX lighting systems usually have multiple universes, each with 512 channels - that's 1024 channels total! If you wanted to add more lights onstage and use DMX for those as well, your console would need to be upgraded from one universe (512 channels) to two or four universes, depending on the size of your venue.

DMX lighting can be a powerful tool in any lighting designer's arsenal - but it is not always easy to set up or use. It also has some limitations that may have you rethinking how we do illumination!

Setting Up DMX Lighting

With so many powerful tools and capabilities, it's no wonder that DMX lighting is a favorite for many lighting designers. However, the process can be difficult to set up!

Step 1: Learn The Ropes

The first step is understanding DMX lighting. If you're new to the world of DMX, we recommend reading some tutorials and getting familiar with the protocol before attempting a setup project yourself.

There are tons of online guides, resources, and videos that you can use to help show you the proper method for setting up DMX lighting protocols for nearly any purpose.

Step 2: Gather Your Tools

Once you feel confident in your knowledge of DMX lights, it's time to gather your materials: cables, connectors, lights, and a DMX lighting controller.

DMX cables are typically sold by the foot, but most installations will need 50 feet or more. If you're installing lights in a large venue like an arena or stadium and want to use DMX lighting for their control, then it is probably best to get 100 feet of cable at least!

The connectors that attach the DMX circuit wire to the lights are often sold with DMX cables, but they may be separate to purchase as well.

Step 3: Connect Your Lights to Your DMX Controller

The next step is to find the light fixtures you want to use with your lights. You'll need at least one light fixture for every channel on your DMX system - so if you're using up most of those channels in your first scene, then it's going to be hard to set up another.

Steps for installing a DMX controller:

  1. Plug in your DMX cable into your console or computer and then plug it into an outlet - this will power on the system.
  2. Label each light fixture using its address (DMX channel number), then plug it into the DMX controller.
  3. Connect one end of a DMX cable to your console or computer, and connect the other end to all light fixtures in that "scene."
  4. Power on each fixture by flipping its switch! Then turn on your console and get started.

If you have more than one scene, then you'll need to set up a new DMX controller for that scene and repeat these steps.

The Pros and Cons of DMX Lighting

As you can imagine, there are many advantages to DMX Lighting that make it a desirable option for most lighting designers. However, there are also cons to DMX lighting's complexity and cost that may keep it out of reach for some.

Pros of DMX Lighting:

  • DMX cables are easy to unplug and move around, which can be a great help if you need to reconfigure your show mid-show.
  • DMX lights can be programmed to change color, dim/brighten, and more.
  • DMX is a versatile tool for lighting designers in any venue size or application - whether it's an arena show with 100+ fixtures onstage!

Cons of DMX Lighting:

  • Requires high end controllers to get the most out of lighting
  • Lots and lots of wires - unless you spring for expensive and unreliable wireless DMX connectors
  • The process of setting up DMX lighting can be complicated without some background knowledge, including how to daisy chain lights and utilizing terminators at the proper location
  • DMX lights are not as energy efficient as some other technologies, so they can be more costly and challenging to maintain over time.

Rethinking DMX Lighting Solutions

Fortunately, for those who are looking for an alternative to DMX lighting, there have been advances in lighting systems using advanced software that cut down on the complexity, cost, and time it takes to put together a professional lighting show.

A new generation of software uses an intuitive, drag-and-drop interface to create professional lighting scenes with ease - without the DMX cables and controllers!

This type of technology can be found in both LED lights and traditional fixtures controlled by pre-programmed sequences built into the fixture itself. This type of lighting system is a great alternative to DMX for anyone who wants control and versatility but doesn't want to deal with complex setups.
