Product Description

Our Splitters  SP-404 (1×4 SDI) / SP-406(1×6 SDI) receives one SDI input, perfectly duplicates it, and re-transmits four SDI outputs for real time multi-viewing. It is a reliable video device splitting a SDI, HD-SDI, or 3G-SDI video source to (four or six) SDI compliant displays at the same time.



  • 3G/HD/SD triple-rate distribution
  • Four/Six separately buffered and reclocked outputs
  • Cable equalization (Beldon 1694A) and signal retiming
  • Dual color LED indication of input lock and rate
  • Pass all ancillary data
  • Provides automatic input cable equalization up to 300m (1000ft)@SD, 150m (500ft)@HD and 60m(190ft)
  • Reclocking SDI signals for cascading and thus longer transmission
  • Inter-locked power supply for better fixedness
