Over the past several decades wireless technology has left its mark in the field entertainment technology. Examples of entertainment technology include:
• Scenery fabrication
• Show control
• Interactive environments
• Computer simulation
The reason for the growth in technology and popularity in entertainment technology has been due to the public’s desire to have a truly immersive experience be it in a theatre, at a play or at a concert. One of the technologies that have aided this boon is wireless DMX. Yet despite its rising importance in enhancing the public’s entertainment experience, many people are still not aware of what this DMX is. So what is wireless DMX? What are its uses? What are its advantages over what preceded it? Here is a primer for those who are new to the concept of wireless DMX.
What is Wireless DMX?
Wireless DMX is a communications protocol that was created as a common language for lighting controllers to speak to lighting devices – such as dimmers – without the use of data cables. As wireless technologies have grown in other areas, DMX is now relatively inexpensive and used widely in stage productions, concerts and theatres. The use of wireless DMX has been as varied as lighting used to illuminate the White House, the Pope and the rock group U2’s tours. It was even used for the opening ceremonies of the London Olympics in 2012.
Why use Wireless DMX?
Wireless DMX represents a revolution in lighting. DMX controllers give the operator greater control and flexibility over older wired systems. Wireless DMX is quicker, easier and more economic than the wired systems of the past. (DMX cable costs $1.00 or more per foot.) Additionally, wireless DMX is superior to RF control. Next, wireless DMX allows for adaptive frequency hopping which picks out only open radio frequencies to broadcast on (thereby not interfering with other signals.) Lastly, DMX has already become nearly universally accepted as the communication protocol among lighting professionals. Anyone who still uses cables is resisting an advancing technology that will only grow in the future making entertainment venues more immersive. In short, wireless DMX is the future and the future is here. Because of this, we sell dimmers, wireless DMX receivers, controllers and other devices that lighting professionals have come to rely upon.
