What Should You Consider Before Installing a DMX System?

Before embarking on the installation of a DMX system, a realm of considerations awaits, akin to the subtle notes that compose a grand symphony. To ensure its harmonious orchestration and alignment with your artistic vision, allow me to guide you through these essential contemplations, here are the things you need to consider:

1. The Number of Fixtures

Figure out how many fixtures you have. Each fixture, a celestial body in its own right, commands a certain number of channels, weaving a tapestry of light and color.

As the number of fixtures grows, so too does the complexity of your system, an intricate dance of channels that demands careful planning. 

The number of fixtures you have affects how complex your system is and how many channels you use.

A single DMX universe, like a boundless canvas, accommodates up to 512 channels. Should your creative ambitions extend beyond this limit, requiring a richer palette or a more intricate choreography of light, you must embrace the expanse of multiple DMX universes or the sophistication of advanced controllers.

2. The Number of Channels

Each RGBW Wall Washer fixture uses a specific number of DMX channels based on its features.

A humble RGB light, for instance, might require a mere triad of channels—red, green, and blue—while a majestic moving-head fixture, with its panoply of features, could command a retinue of 15 channels or more.

To ensure seamless integration, meticulously tally the total number of channels demanded by your ensemble of fixtures, confirming their harmonious coexistence within the confines of your chosen universe.

This meticulous planning forestalls the discord of overlapping channels, ensuring that each fixture receives its due command, and that the symphony of light unfolds as envisioned.

Imagine, if you will, a scenario where you plan to control a series of LED par cans, each requiring three channels for RGB color mixing, alongside several moving head fixtures, each needing 16 channels for pan, tilt, color, and gobo control. If you have 20 LED par cans and 6 moving heads, your channel count would be:

(20 LED par cans * 3 channels) + (6 moving heads * 16 channels) = 60 + 96 = 156 channels.

This total comfortably fits within a single DMX universe, leaving ample room for additional effects or fixture adjustments.

3. The Wattage for Each Fixture

The wattage—the lifeblood of every luminary! Each fixture, with its unique appetite for power, demands careful consideration. It is not merely a matter of plugging in and hoping for the best; it is a delicate dance of volts and amperes. For the grand installations, where a symphony of lights converge, the cumulative wattage can surge to breathtaking heights. Imagine a constellation of high-wattage fixtures, each clamoring for energy, threatening to overwhelm the circuits.

Check the wattage and power requirements for all your fixtures to make sure you have enough power in your electrical system to handle everything. This is especially important for big installations where you have a lot of big, high-wattage fixtures.

Make sure you have power distribution systems like DMX splitters or power relays that can handle all your fixtures without overloading circuits.

In such scenarios, DMX splitters and power relays are not mere accessories; they are the linchpins of the entire operation. 

Additional Considerations:

Cabling and Signal Distance: Use real DMX cables, not regular audio cables, and keep your cable lengths within recommended limits (usually under 300 meters for DMX signal). Use DMX terminators to stop signal interference.

Controller Compatibility: Verify that your DMX controller supports the number of fixtures and channels you need.

Future Expansion: Plan for potential growth, leaving room for additional fixtures or features.

Fixture Addressing: Ensure fixtures are addressed correctly to avoid control conflicts.

Proper planning based on these considerations will ensure a reliable and efficient DMX lighting system tailored to your needs.

By embracing these considerations, you embark on a journey of informed decision-making, transforming the installation of your DMX system from a mere technical endeavor into an act of artistic creation. May your symphony of light resonate with brilliance, illuminating the world with its beauty and power.
