Galileo SX Ground Block
DEMO, mint condition

The heart of your system.

The Galileo Active Ground Block is a top to bottom re-engineering of their award winning Active Ground Block SE with technology originally designed for the Galileo SX PowerCell as well as new technologies expressly developed to make this the world’s highest performance ground filter for your A/V system.

Synergistic Research starts with a new chassis machined from a solid billet of aluminum and carbon fiber to address unwanted vibration and chassis resonance that would otherwise lower your system’s performance. The internal Electromagnetic Cell increasing the number of active filters from one as found in our Active Ground Black SE to three Active Em Cells with Galileo SX PowerCell technology was re-engineered. This includes two rolled EM Cells in carbon fiber housings to control resonance and one flat Carbon Fiber Electromagnetic Cell with a copper mesh ground plane as found in our Galileo SX PowerCell. In addition, the gain was turned up in a new ULF Generator for three times the signal strength of the Active Ground Block SE for a significant gain in performance. And since the Galileo Ground Block was developed in conjunction with the limited edition 2nd Generation Galileo SX PowerCell it shares its ability to custom tune the sound of the ground filter to compliment your system and personal tastes by changing the bias frequency of the ULF signal generator. By pressing a button on the back of the Galileo Ground Block you change the frequency that biases its three Active EM Cells and this changes the characteristic sound of your system. There is a default setting shared with the current Active Ground Blocks and three new frequencies that make your system sound more liquid or dynamic and holographic; the choice is yours. And to make keeping track of which frequency you have selected easy, when you press the button, it changes the color of the light inside the unit, visible from the view window on the top of the unit. New useful features were added like the ability to directly wire both your PowerCell line conditioner and Atmosphere Acoustic Field Generator to increase their performance.

New Galileo SX ULF Generator: 4 ULF settings.
The Galileo SX Ground Block with a redesigned circuit controls the heart of the ground conditioner; its Electromagnetic Cells. This new circuit includes new UEF Orange Capacitors built with the same technology as our award-winning Purple Fuses for a lower perceived noise floor and better overall musicality. The circuit itself has 3 times the output strength of the circuit it replaces to increase the filtration power of all the internal Electromagnetic Cells. But perhaps the most exciting feature is the variable ULF signal generator frequency so you can custom-tune your system’s sound. Just press a button to select between four harmonics of the Earth’s Schumann Resonance used to bias the Galileo SX Ground Block’s internal Electromagnetic Cells. In the past, the Active Ground Block’s ULF frequency generators had only one harmonic of the Earth’s Schumann Resonance selected for its ability to compliment as wide a variety of systems as possible. Now you can choose the original frequency as default or select between three additional frequencies that run the gambit from a highly focused sound to a vastly holographic and enveloping sound, or choose a fourth frequency that splits the difference. The choice is yours!

Four frequency bias, one perfect sound.
– Purple Frequency: When you select the Purple Frequency, you will see a purple light illuminating the internal circuit of your Galileo SX Ground Block. Purple is the default setting for systems that have a Synergistic Research Atmosphere or FEQ Acoustic Field Generator. Choose this setting when you want a cross between the Blue and Red frequency’s sonic balance.
– Blue Frequency: When you select the Blue Frequency, you see a blue light illuminating the internal circuit of the Galileo SX Ground Block. This is the most focused sound option with strong dynamics and precise imaging with a more forward sound than the other options.
– Red Frequency: When you select the Red Frequency, you see a red light illuminating the Galileo SX Ground Block’s internal circuit. This is the setting if you want to maximize soundstage scale with a deep soundstage that also envelops your listening position. This setting works best when you also have Synergistic Research acoustic products like HFT’s, Black Boxes, and Atmosphere or FEQ acoustic field generators.
– Green Frequency: When you select the Green Frequency, you see a green light illuminating the Galileo SX Ground Block’s internal circuit. Green is the default setting if you do not have an Atmosphere Acoustic Field Generator in your system. Fun fact, Green is the default bias frequency for the original Galileo SX PowerCell / Active Ground Block SE.

2 each 25 % Larger Folded EM Ground Cells.
Now biased with Galileo SX ULF Generator. The two-carbon fiber tubes you see in the Galileo SX Ground Block are folded Active Electromagnetic Cells. The folded cells have been used on SR Power conditioners for years, but Galileo SX Ground Block is the first SR Ground device to incorporate these cells which are 25 % denser than prior folded EM Cells; this means greater filtration for a lower noise floor and enhanced dynamics. We also bias the folded EM Cells plus the flat EM Cell, below the center copper mesh, with the new multi-setting Galileo SX ULF generator. Prior SR active ground devices only bias the single flat EM Cell. 25 % more filtration combined with biasing the EM Cells improves your system’s ability to soundstage over the already excellent soundstaging of other SR ground devices.
