Synergistic Research
SX Active Ground Block
March 2025 Promotion!

Sky high performance starts at ground

The new Active Ground Block SX is a technological trickle-down of the Synergistic Research cost-no-object Galileo Active Ground Block plus new technologies that were not developed when they first engineered the Galileo Active Ground Block. First, SR started with a Galileo-style chassis machined from a solid billet of aluminum plus carbon fiber to lower distortion related to mechanical vibration. Next, they developed a power supply with technology and lessons learned from their LPS or Linear Power Supply development program for the lowest noise floor of any Active Ground Block to date. They then dialed up the performance of their ULF bias of ground by introducing dual harmonics of the Schumann Resonance instead of just one with technology developed for the upcoming 2023 Galileo PowerCell.

SR also focused on making the new Active Ground Block SX more practical than the popular PowerCell SE by upping the number of ground points from 22 to 32. This means you can ground an additional ten components, cable shields, system racks, or anything in your system made from a conductive material to maximize system performance. Finally, audition the Active Ground Block SX in your system and discover why Synergistic Research says ultimate performance starts at ground level.
