Atlas Hyper Achromatic X RCA-BNC Is an Advanced 75 Ohm Digital S/PDIF Interconnect for Streamers and DACs
Atlas Hyper Achromatic X RCA-BNC is a high-precision 75 Ohm digital interconnect cable optimised for the critical connection between a CD transport or high-resolution streamer and a DAC. Designed specifically for systems that employ BNC socketry, this premium interconnect eliminates impedance mismatch by maintaining a true 75 Ohm characteristic impedance from end to end. The result is a clean, distortion-free digital signal path that preserves timing integrity and reduces jitter — especially vital in high-fidelity systems where signal purity is non-negotiable.
This particular configuration, RCA to BNC, is ideal for setups requiring inter-format digital compatibility without resorting to plug adapters, which often introduce signal degradation. For digital audio systems using BNC inputs, the Atlas Hyper Achromatic RCA-BNC provides a more robust, reliable, and sonically transparent alternative to standard RCA-based cables.
Hyper Achromatic X RCA-BNC Features Cold-Weld Solder-Free Connectors to Preserve Signal Integrity
Atlas Hyper Achromatic X RCA-BNC features the brand’s proprietary cold-weld Achromatic X connectors. This solder-free technology removes one of the most common points of failure in traditional cable assembly — the break in signal continuity due to soldered joints and shielding deformation. Instead, the Achromatic X connectors create a mechanically stable, high-conductivity interface that avoids compressing the cable’s shielding, a factor that can otherwise lead to impedance distortion and increased jitter.
By eliminating this compression and maintaining a consistent mechanical geometry, the Achromatic X design delivers enhanced timing accuracy, lowered noise floor, and superior phase coherence — all crucial attributes in a digital interconnect where bit-level fidelity governs performance. This advanced connector system builds on Atlas’s original Integra concept, evolving it further with lower contact resistance, non-conductive ABS plug bodies, and calibrated tolerances to ensure consistency across every cable.
High-Purity Silver-Plated OFC Conductor and PEF Dielectric Ensure Fast, Clean Signal Transfer
Atlas Hyper Achromatic X RCA-BNC is engineered with a silver-plated OFC (Oxygen-Free Copper) central conductor, selected for its excellent conductivity and fast transient response. The silver-plating enhances the skin effect performance, benefiting high-frequency signal transmission common in S/PDIF digital audio.
Surrounding the core conductor is a precision-applied PEF (Physical Expanded Foam) dielectric, a material with exceptionally low dielectric loss. This choice of insulation contributes to the cable’s low capacitance — measured at just 62.805 pF/m — ensuring minimal signal delay and virtually no time-smearing effects. It also helps retain the signal’s original energy, delivering a more lifelike and uncompressed digital audio stream.
The Atlas Hyper Achromatic’s precision-matched impedance and low inductance (1.407 µH/m) mean that the square waveforms of digital audio signals retain their integrity, reducing reflections and rounding that can lead to audible degradation.
Dual-Drain System and Full 360° Shielding Deliver Near-Total RFI Rejection
Atlas Hyper Achromatic X RCA-BNC features a fully engineered shield structure comprising a combination of foil and OFC braided layers. This multi-layered screen is further enhanced by Atlas’s innovative dual-drain system — a symmetrical twin conductor approach that ensures the shielding is grounded uniformly along its entire circumference without distorting or twisting the shield geometry during termination.
This meticulous implementation provides a full 360° RFI (Radio Frequency Interference) rejection, crucial in environments where wireless signals, switching power supplies, and network equipment can otherwise introduce unwanted digital noise. The result is a clean, uninterrupted signal path that prevents digital artefacts and preserves the resolution and timing of the original source material.
Combined with its precise impedance characteristics and low resistance (0.04364 Ohms/m), this construction ensures the cable can operate without being the weak link in a high-resolution digital audio chain.
RCA to BNC Format Offers Ideal Compatibility Without the Compromises of Adapters
Atlas Hyper Achromatic X RCA-BNC interconnects are purpose-built to provide optimal digital signal transfer between mismatched connection formats, specifically from RCA-equipped transports to DACs or processors with BNC digital inputs. Rather than relying on plug adapters — which can introduce signal reflections, poor contact points, and impedance discontinuity — Atlas offers factory-terminated, impedance-matched solutions that preserve the electrical integrity of the link.
Also available in BNC-BNC configurations, the cable caters to systems where BNC is used exclusively for its superior impedance performance. By offering RCA-BNC and BNC-RCA terminations natively, Atlas ensures flexibility in digital setups without sacrificing audio quality or signal reliability.
With an outer diameter of 8.5 mm and a gloss black finish, the cable is designed not only for performance but also for durability and elegance in premium audio environments.
Achromatic X RCA Connector Represents Atlas's Most Advanced Low-Mass Interface
Atlas Hyper Achromatic X RCA-BNC uses the Achromatic X RCA connector, a next-generation development derived from the company’s foundational Integra design. Crafted with a low-mass, non-conductive ABS body and high-tolerance mechanical contacts, the Achromatic X RCA minimises eddy current distortion and capacitive loading — both of which can smear transient details in digital signals.
The plug’s internal structure features a calibrated clamp mechanism that provides consistent termination pressure, optimising the contact surface and reducing micro-arcing over time. In contrast to conventional CNC-machined metal-bodied plugs, which often increase unwanted capacitance and reflect signal energy back into the cable, the Achromatic X design ensures optimal signal transfer and mechanical reliability.
This approach reflects Atlas’s wider design philosophy — where every element of the cable, from conductor to connector, must work in harmony to eliminate distortion and maximise transparency.
Atlas Hyper Achromatic Series Is Built for Digital Purity and System Compatibility
Atlas Hyper Achromatic X RCA-BNC belongs to the acclaimed Hyper series, which targets discerning digital audio systems where clock precision and noise rejection are paramount. Whether used between a high-end streamer like the AURALiC Aries, a CD transport from Cyrus, or a DAC from Chord Electronics, this interconnect is engineered to preserve signal integrity over distance.
Every detail — from the silver-plated conductor and ultra-low-loss PEF dielectric, to the precise 74.2 Ohm impedance and cold-welded Achromatic X connectors — contributes to a digital link that performs audibly and measurably above standard coaxial cables. For systems using BNC sockets, this version of the Hyper interconnect delivers a significant upgrade in signal fidelity, jitter control, and overall sound clarity.
