You can fit these all in the same universe of control, however, if you have more than 32 devices.

Let’s say you have 40 lighting fixtures that use three channels each: you are only using 120 channels total. Note that the 512-channel limit is independent of the 32-light fixture limit. Lights can also have multiple personalities, or profiles, depending on how much or how little control you want.

Each lighting fixture you have uses a number of DMX channels depending on how many parameters the fixture has. DMX Channels / UniverseĪ DMX line is limited to a total of 512 channels, which is also called a universe. You cannot use Y-cables, as this approach does not electrically isolate the DMX lines and would cause data reflections. A splitter like the Chauvet DJ Data Stream 4 will allow you to have 32 devices connected to each DMX output connector. If you have more than 32 light fixtures, you would need to use an Opto-Splitter. You cannot have more than 32 devices connected on a single chain. The different impedance between these cables matters with lighting networks and can cause your lights to either not respond or respond sporadically. DMX cables use roughly 110-ohms whereas microphone cables are typically around 45 ohms. Don’t confuse them with 3-pin audio or mic cables. This is why you may sometimes see fixtures with a 3-pin, 5-pin, or both connectors on the fixture. Over the years, the second pair of pins (pins 4 & 5) on the connector stopped being used, since 3-pin DMX proved to be very reliable. The reason for five pins is that pin 1 would be the ground, pins 2 and 3 would be data link 1, and pins 4 and 5 were reserved for data link 2 and/or proprietary data.

DMX networks typically only have one master device on the network, usually the DAW software / controller, and many slave devices - the lights.

DMX InterfaceĭMX (Digital Multiplexing) or, officially, USITT DMX512, is a unidirectional serial data protocol, meaning the signal leaves the controller (computer or lighting board) and travels through all lighting fixtures in a daisy-chain. To hang your lights, you can get a lighting stand with T-Bar. It is the most versatile stage lighting option.Ībove are only some of the more common types of lights. It offers different beam angles for spot (narrow), wash (wide), beam (laser) and hybrid light effects.
