Doug Fleenor 1211-5 DMX Isolated Splitter

This unit has one input and 11 outputs (5-pin XLR - standard w/ input feed-thru). It is in good working and cosmetic condition.

The Doug Fleenor 1211-5 DMX Isolated Splitter is designed to distribute a single DMX control signal to multiple DMX lines reliably, making it ideal for lighting systems that need clean signal distribution to dimmers, moving lights, color changers, and other DMX receivers.

Electrical Isolation for Cleaner, More Reliable DMX

Each output is electrically isolated from the input, and from every other output, by 2500 volt optical couplers. Each output has its own line driver and associated power supply. This isolation helps reduce the risk of noise, ground issues, and faults on one DMX run affecting the rest of your system.

Star Distribution Without the Problems of a “Wye” Split

The DMX splitter allows connection of DMX receivers (dimmers, color changers, moving lights, etc.) in a star configuration as opposed to a daisy chain configuration. In a star configuration, each control cable is run to a central point, in this case the splitter. In a daisy chain configuration all the devices are connected on one control cable, the output of one feeding the input of the next. It is not good practice to simply split a DMX control cable using a "wye" cable as this can cause signal corruption due to reflections.

Typical Applications

Typical uses of the splitter include splitting the control signal between stage right and stage left dimmers, running an isolated split to a string of color changers, splitting and isolating a feed to a wall outlet for temporary or rented dimmers, isolating a stack of dimmer packs from each other, etc.
