DMX splitters are digital network components which take in the DMX signals as input and splitting it out electronically by copying the data stream. The splitter then shoots out the signal as a light-beam of signal across a small gap inside the unit; which electrically isolates the signal. To keep it simple, it multiplies DMX signals from a single cable to numerous others such that we get an accurately amplified and duplicated signal. It safeguards against electrical faults on other lines. Splitters enhance networking possibilities by not only dividing signals but also boosting them through added daisy chains or remote cable extensions. You can even link Multiple DMX’s collectively. The inputs and outputs characteristically have sets of three- or five-pin XLR type connections. The outputs can be optically isolated to shield against power spikes, thus guarantying more consistent performance.

There are infinite reasons and needs to split DMX signals. DMX splitters are so designed to host up to max 32 fixtures, all leading back to a single control deck. If you own numerous fixtures that you want to connect at a time; it makes daisy-chaining damn difficult as you start to face data problems. If you are an amateur in this field, read our post below.

In the following situations; we suggest you to use DMX Splitters to split your DMX signal:

1. When you own 32 plus devices on one line but the DMX standard supports 32 devices per daisy chain of lights so that you get perfect signal strength.
2. When you need lights in every corner of your show. It’s better to split DMX rather than drawing cables far and wide to distant areas in your compound.
3. If you need to go over 1800 feet in cable length.
4. If you use different power panels for your lights or consoles.
5. For professionals, we suggest to split DMX to each lighting position. If a fixture goes haywire or a cable gets tripped, snagged or unplugged; during such faults that particular light goes down saving the other lighting rigs.

We have also listed how NOT to split DMX signals. Splitting DMX the wrong way can result in huge problems like dropping out of fixtures to fixtures flickering or flashing. DMX cannot be split with a y-cable, because it is the data you work with. You can use a y-cable but they relentlessly interfere with the signal strength of your DMX. It also degrades the signal strength if either of the y-cables are longer than a couple inches. In totality, a y-cable is a strict NO for splitting DMX Signals.

A DMX splitter is an indispensable component of a professionals’ toolkit and is highly recommended for amateurs who are just starting out. DMX splitting is both of a boon and bane. If done the right way; is an even-handed investment that will make life simple, solve problems and make your lighting system less error-prone. Done inaccurately, and you will have a world of trouble on your head. Hopefully that’s not how this post was! Happy splitting!
