Active Ground Block SX / The Heart of Your System


The new Active Ground Block SX is a technological trickle-down of our cost-no-object Galileo Active Ground Block plus new technologies that were not developed when we first engineered the Galileo Active Ground Block. First, we start with a Galileo-style chassis machined from a solid billet of aluminum plus carbon fiber to lower distortion related to mechanical vibration.

Next, we developed a power supply with technology and lessons learned from our LPS or Linear Power Supply development program for the lowest noise floor of any Active Ground Block to date.

We then dialed up the performance of our ULF bias of ground by introducing duel harmonics of the Schuman Resonance instead of just one with technology developed for our upcoming 2023 Galileo PowerCell. We 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 we say ultimate performance starts at ground level.
