INTRODUCTION
The SP-3004KG 1x4 12G/6G/3G/HD/SD-SDI Distribution Amplifier with Reclocking 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, 3G-SDI, 6G-SDI, or 12G-SDI video source to four SDI
compliant displays at the same time.
FEATURES
● 12G/6G/3G/HD/SD-SDI distribution
● Four separately buffered and reclocked outputs*
● Cable equalization and signal retiming
● LED indication of signal lock and video rate
● Passes ancillary data and embedded audio
● Provides automatic input cable equalization (Belden 1694A) up to 180m (594ft)@3G, 100m
(330ft)@6G and 70m(230ft) @12G
● Reclocking SDI signals for cascading and thus longer transmission
● Inter-locked power supply for better fixedness

Pair B Output 3 & 4
PACKAGE CONTENTS
● 1x SP-3004KG
● 1x 5V power adapter
● 1x BNC 75 ohm terminator
● 1x User Manual
*Due to the super high frequency and lower jitter requirement for 12G SDI signals, to have
the best performance, it is strongly recommended to use one 75 ohm terminator if the
paired SDI is not in use.
Please see the following table for 12G SDI output pairing.
