Synergistic Research Active Ground Block SX

Synergistic Research Active Ground Block SX

The Synergistic Research Active Ground Block SX is a powered, multi-connection audio grounding solution designed to build a dedicated system-grounding network around compatible hi-fi components and cables. It combines the company's UEF treatment approach with active electromagnetic cell biasing and an internal ultra-low-frequency generator.

Manufacturer technology and design

Compared with a passive ground hub, the SX adds an actively controlled electromagnetic filtering architecture. Synergistic Research describes a chassis machined from aluminium and carbon fibre to control mechanical resonance, together with a redesigned linear supply and dual-harmonic ULF generator. The product provides 32 small-format grounding connection points, enabling a more extensive network for supported components, cable shields and Synergistic Research accessories.

Key features

• 32 dedicated 2mm system-ground ports
• Active UEF electromagnetic ground-conditioning architecture
• Internal dual-channel ULF-frequency bias generator
• Low-noise active power supply and mechanically controlled aluminium/carbon-fibre chassis
• Compatibility with specified Synergistic Research grounded cable systems
• Manufacturer-recommended applications include suitable turntables, phono stages, DACs and preamplifiers

Who is it for?

Consider the Active Ground Block SX when you want to plan a coordinated grounding scheme across several high-end components. Compatibility depends on how each device's ground, chassis and signal interfaces are constructed; never connect an arbitrary output or ground terminal without approval.

Frequently asked questions

Will it work with any product with an RCA socket? Not automatically; the manufacturer lists grounding methods for specific interfaces and cables, which must be checked per installation. Does it provide protective mains earthing? No, and it must not be used as a substitute.
