INTRODUCTION
The SP-3004G 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
SDI compliant displays at the same time. Besides, built-in re-clocking & equalization features provide the
best performance for SDI distribution amplifier.
FEATURES
● 3G/HD/SD triple-rate distribution
● Four separately buffered and reclocked outputs
● Cable equalization (Beldon 1694A) and signal retiming
● Dual color LED indication of input lock and rate
● Passes all ancillary data
● Provides automatic input cable equalization up to 300m (1000ft)@SD, 150m (500ft)@HD and
60m(190ft)
● Reclocks SDI signals for cascading and thus longer transmission
● Inter-locked power supply for better fixedness
