If you\u2019re reading this, chances are you work in the live events, theater, or architectural lighting space\u2014you know the kind of chaos that comes with setting up gear for a show, conference, or permanent installation. Last month, I got a frantic call from a regular client of mine, a production manager who had just wrapped up a 3-day festival. He told me half his DMX splitters were dead before he even loaded them into his van at the end. One had a corroded power port, another had a cracked casing from being stuffed into a too-tight equipment case, and the third wouldn\u2019t output any signal at all because a few DMX pins were bent. DMX Splitter<\/a><\/p>\n

<\/p>\n

This isn\u2019t an isolated incident. As someone who\u2019s been selling DMX splitters for over a decade now\u2014 I\u2019m the guy you call when you need 8-channel splitters for Broadway tours or compact units for small pop-up events\u2014 I\u2019ve seen way too many splitters get written off prematurely because of bad storage habits. A DMX splitter might look like a hunk of metal and plastic, but it\u2019s a precision piece of gear. Its job is to take the weak DMX signal from a controller, amplify it, and send it to dozens of fixtures without dropouts or flicker. Skimp on storage, and you\u2019re not just risking the splitter itself\u2014you\u2019re risking an entire show, event, or project.<\/p>\n

Today, I want to walk you through exactly how to store a DMX splitter properly. These aren\u2019t just random tips I picked up; they\u2019re lessons I\u2019ve learned from years of working with lighting teams, fixing broken gear, and refining our products to hold up to the abuse the industry throws at them.<\/p>\n

First, let\u2019s talk about the biggest enemy of any electronic lighting gear: environmental damage. DMX splitters are designed to work in a range of temperatures and humidity levels, but when they\u2019re not in use, that range narrows fast. I\u2019ve seen splitters left in the bed of a work truck during a summer shoot where temperatures hit 110\u00b0F, only to have their internal power supplies fry a week later when they were stored in a cold, damp warehouse over the winter. Or worse, left in a venue\u2019s unairconditioned storage closet during a rainy season, where condensation seeped into the ports and shorted out the circuit boards.<\/p>\n

The sweet spot for storing DMX splitters is a dry, temperature-controlled space. That means keeping the area between 50\u00b0F and 77\u00b0F (10\u00b0C to 25\u00b0C) with a humidity level of 40% to 60%. No basements, no attics, no van trunks left parked in the sun\u2014those spaces swing wildly in temperature and trap moisture. If you don\u2019t have a dedicated climate-controlled storage area, here\u2019s a quick hack I recommend to our clients: keep a few desiccant packs (the kind you get in new electronics packaging) in each equipment case or storage bin with your splitters. They\u2019ll absorb excess moisture and prevent condensation buildup. For clients who work in especially humid climates, we even sell moisture-resistant storage bags for our splitters\u2014they\u2019re lightweight, tear-proof, and have a small vent that lets air circulate while keeping out humidity and dust.<\/p>\n

Next up, handling and protection during storage. This is the part where most people cut corners. When a show ends, everyone\u2019s in a hurry to pack up and move to the next venue. Splitters get tossed into cases with cables, stands, and fixtures, their ports exposed to whatever sharp edges or heavy cables are laying around. Let\u2019s go back to that 8-channel splitter that died on my client last month\u2014it had a bent DMX data pin that was caused by a coiled XLR cable being slammed into the port while the splitter was stuck under a stack of par cans. A bent pin doesn\u2019t just look bad; it can ruin an entire DMX universe because it interrupts the signal.<\/p>\n

The fix here is simple, but it requires a little extra attention during packing. Every DMX splitter we sell comes with protective rubber caps for all its ports\u2014we don\u2019t skimp on these because we know how important they are. The first rule: always put those caps back on before you stow the splitter away. The caps are made of thick, flexible rubber that will absorb impact and keep dust, dirt, and moisture out of the pins. Don\u2019t just leave the ports open\u2014even a small speck of dirt can cause signal interference when you go to use the splitter next.<\/p>\n

Then, don\u2019t stack heavy gear on top of your splitters. That 200-pound lighting truss section you\u2019re bringing back from a tour? Put it on its own shelf or at the bottom of your equipment case, not on top of a bin of small splitters. Our splitters are built with durable aluminum casings, but they\u2019re not indestructible. A heavy object pressing down on the casing can crack the circuit board inside or warp the metal frame, which will throw off the signal amplification when you power it up. If you\u2019re storing splitters loose, not in cases, keep them separated\u2014never stack them directly on top of each other without a layer of padding in between. A folded towel or a piece of foam works perfectly here.<\/p>\n

Cable management might seem like it has nothing to do with storing the splitter, but it\u2019s a huge part of keeping the splitter in good shape. When you pack a splitter, you\u2019ll have power cables and DMX cables attached to it. If you just coil those cables up and yank them off the splitter, you risk pulling the ports loose from the circuit board over time. Instead, disconnect all cables gently, and don\u2019t leave cables coiled tight around the splitter while it\u2019s in storage. Tight coils can put constant stress on the port connections, leading to broken wires or loose pins over months of storage. I teach our clients to bundle loose cables with soft velcro straps (never metal twist ties\u2014those can scratch the casing and leave sharp edges that damage gear) and store them separately from the splitters. If you have to leave a cable attached for a temporary storage period, make sure it\u2019s not stretched tight or bent at a sharp 90-degree angle\u2014sharp bends can damage the internal wire insulation and cause signal drops later.<\/p>\n

Wait, what about power? If you leave a DMX splitter plugged into power 24\/7 in storage, is that a bad thing? A lot of people ask me this, and the short answer is: it depends. Our splitters are designed with built-in surge protection and power regulation, so a small amount of trickle power won\u2019t hurt them. But if you\u2019re storing splitters for weeks or months, leaving them plugged into an unregulated power source (like an old outlet with frequent voltage spikes) can shorten their lifespan. I recommend two options: if you\u2019re storing splitters short-term (under a month), it\u2019s fine to leave them unplugged, but if you want to be extra cautious, plug them into a surge protector. If you\u2019re storing them long-term (more than a month), definitely unplug them from power. Constant power flow, even low-level, can degrade internal components like capacitors over time. If you\u2019re worried about keeping them ready to go for a quick callout, test them once every 3 months: plug them in, run a quick signal test with a simple controller, and check that all channels are outputting correctly. It only takes 5 minutes, and it can save you from a disaster when you need gear in a pinch.<\/p>\n

Another point that\u2019s often overlooked: labeling and organization. I can\u2019t tell you how many times a client has called me saying they have 10 splitters in storage, but they have no idea which ones are 4-channel, which are 8-channel, or which have been tested recently. When you store splitters without labeling them, you end up digging through a pile of gear, wasting time looking for the right one, and possibly tossing a broken one with a good one because you can\u2019t tell them apart. We always include blank labels with our splitters, and I tell every customer to use them. Label each splitter with its model number (for example, \u201cDS-8: 8-channel DMX splitter\u201d), its last calibration date (if you calibrate them periodically, which we recommend every 2 years), and any notes about its performance (like \u201cworks best for outdoor use\u201d or \u201cminor signal drop on long runs\u201d). When you put them away, group like splitters together\u2014all small 4-channel units in one bin, all high-output 8-channel units in another. That way, when a show comes up, you can grab exactly what you need in 2 minutes instead of 20.<\/p>\n

I also want to address a common misconception: some people think \u201cindustrial-grade\u201d splitters don\u2019t need proper storage. We build our splitters to handle rough use on tour, in venues, and in construction sites, but that doesn\u2019t mean they\u2019re unbreakable. Even the most durable circuit boards will fail prematurely if they\u2019re stored in damp, cold spaces with heavy objects stacked on them. Last year, a client of ours rented 12 splitters for a permanent architectural lighting project for a mall. They stored them in a back closet during the 3-month build, and when they went to install them, half wouldn\u2019t output signal because the circuit boards had corroded from the mall\u2019s high humidity. We replaced them, but it cost the client thousands in extra labor and delayed the project. That could\u2019ve been avoided with a simple desiccant pack and a well-ventilated storage shelf.<\/p>\n

Let\u2019s wrap this up with a quick checklist you can print out and tape to your equipment room wall, so you never forget the steps:<\/p>\n

    \n
  1. Store in a dry, temperature-controlled space (50-77\u00b0F, 40-60% humidity). No vans, basements, or attics.<\/li>\n
  2. Always put rubber port caps back on before storage to protect pins and ports.<\/li>\n
  3. Never stack heavy gear on top of splitters; separate them with foam or towels if stacked.<\/li>\n
  4. Disconnect all cables, bundle with velcro, and store cables separately from splitters.<\/li>\n
  5. Unplug from power for long-term storage (over 1 month); test every 3 months if stored for extended periods.<\/li>\n
  6. Label each splitter clearly and group like units together for easy organization.<\/li>\n<\/ol>\n

    <\/p>\n

    At the end of the day, DMX splitters are workhorses for your events. Taking 5 extra minutes to pack them correctly and store them the right way will extend their lifespan, save you money on replacements, and keep you from the panic of a gear failure mid-show. We\u2019ve been making DMX splitters for all types of applications\u2014from small theater productions to large stadium tours\u2014and we stand behind every unit we sell. If you have questions about which splitter is right for your storage setup, if you need bulk units for your upcoming projects, or if you want advice on maintaining your gear, don\u2019t hesitate to reach out for a conversation about your specific needs. Your events deserve reliable gear, and we\u2019re here to help make sure that\u2019s what you have.<\/p>\n
