Atlas Element Achromatic X RCA S/PDIF Delivers True 75 Ohm Signal Integrity
Atlas Element Achromatic X RCA S/PDIF is a precision-engineered 75 Ohm digital interconnect designed for uncompromised signal fidelity between high-resolution streamers, CD transports, and DACs. This coaxial digital cable is the natural companion to Atlas’ award-winning Element Achromatic X RCA analogue interconnects and brings superior coherence and clarity to digitally connected audio systems.
Engineered to maintain strict 75 Ohm impedance across its entire length and structure, the Element Achromatic X RCA S/PDIF eliminates the impedance mismatches often introduced by poorly designed connectors and cable geometry. Many interconnects fail to meet the true 75 Ohm digital transmission standard due to manufacturing shortcuts, but Atlas ensures precise control over construction tolerances and materials to avoid reflections and data jitter.
The result is a stable, noise-resistant, low-distortion signal path ideal for connecting source components to digital-to-analogue converters with maximum transparency and timing accuracy.
Atlas Achromatic X RCA Connectors Enable Pure Signal Transfer
Atlas Achromatic X RCA connectors are the foundation of the cable’s performance, employing next-generation cold-weld, solder-free design for ultra-low resistance and mechanical stability. The unique low-mass architecture rejects electromagnetic and radio-frequency interference by removing unnecessary conductive material from the connector body, a key advantage over traditional CNC-machined metal-bodied RCA plugs.
Developed from years of research into dielectric and conductive properties, these connectors use non-conductive ABS bodies with a low dielectric constant to reduce signal smearing and dynamic compression. The solid OFC (Oxygen Free Copper) centre pins, enhanced with a rifled profile, offer precise conductor alignment during cold welding, ensuring optimal contact and conductivity. Gold-plated conjugate brackets serve as the return signal path while preserving structural integrity and consistent impedance by gripping without deforming the conductor.
This evolution of the original Integra and Achromatic designs results in Atlas Achromatic X RCA achieving both mechanical longevity and audible precision, making it ideal for audiophiles seeking reliable, interference-free digital transmission.
Coaxial Cable Architecture Supports Error-Free Digital Transmission
Atlas Element Achromatic X RCA-RCA interconnect utilises a coaxial construction with a silver-plated copper conductor and PEF (Polyethylene Foam) dielectric to support high-bandwidth digital signal flow. The use of a true 75 Ohm coaxial geometry ensures precise impedance control from source to receiver, significantly reducing data errors caused by mismatched signal reflection.
A dual-layer shield, consisting of a foil and braided screen, protects the core signal from electromagnetic interference (EMI) and external noise, while the PEF dielectric offers low capacitance and stable electrical characteristics across a wide frequency range. This shielding and dielectric pairing ensures that jitter, the timing deviation that can degrade audio performance, remains minimised even with longer cable runs.
Combined with Atlas' advanced connector interface, the result is a digital cable capable of supporting high-resolution digital audio streams with transparency and musical detail that reflects the source with fidelity.
Achromatic X RCA Enhancements Bring Physical and Acoustic Benefits
The Achromatic X upgrade introduces refinements across mechanical, material, and acoustic dimensions. Atlas has replaced hollow copper alloy pins with solid OFC conductors, enhancing conductivity and structural robustness. These pins now feature a rifled profile, aligning more precisely with the internal conductor during assembly, a feature that ensures better contact consistency and improved signal transfer.
The dielectric inside the Achromatic X plug has also been matched more closely to the cable’s PEF core, reducing signal reflection at the connector-cable boundary—a critical yet often overlooked area of signal degradation. By ensuring continuity across materials and geometry, Atlas eliminates minute distortions that, when compounded, can colour digital audio reproduction.
These incremental but meaningful design improvements further reduce microphony and signal-phase shifts, giving listeners a cleaner, more dynamically responsive soundstage in demanding high-end systems.
Atlas Element Achromatic X RCA S/PDIF Extends Element Series Performance
