DISCONTINUED: This product has now been discontinued. See our DMX Splitter range.


  • Allow DMX and RDM: Normal mode: Splitter actively repeats RDM traffic bi-directionally while level information goes from controller to DMX devices as usual.
  • Filter RDM: Filter Mode: Single button-press allows all RDM traffic to be filtered out for legacy devices which might flicker if they saw the messages on the line.
  • Bypass mode: Bypass Mode: Another button bypasses intelligent RDM functionality completely to work as a traditional DMX splitter would. Also has 1000V isolation between input and output, and between any individual output receptacles. This protects your console from surges on the DMX line, and also keeps any stray voltage from crossing to other DMX chains.
  • Input & ouptuts: 1 DMX 5-pin for DMX Input. And 4 x 5-pin DMX outputs for greater flexibility. Fully compliant with ESTA and USITT standards for DMX512A with RDM and RDM Standard ANSI E1.37-1.
  • Connect and extend: Instead of having to make them all fit within a single daisy chain, each of the four outputs from the RDS4 can be the start of its own chain, and multiple RDS4 can be linked together if needed.
