Arran employs a unique 3D printed liner within the Ultra L plug, reducing mass and the influence of the connector itself to extremely low levels.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"contentIntro barL\" data-mce-fragment=\"1\"\u003e\n\u003cp\u003eThe Arran Ultra L RCA Grun uses the highest quality ‘6N’ (99.99997% purity) elongated crystal copper manufactured using the OCC (Ohno Continuous Casting) process, ensuring the signal follows a faster, cleaner and more direct path.\u003c\/p\u003e\n\u003cp\u003eThe cable utilises a pair of conductors, each made up of six solid OCC strands surrounding a seventh central wire, tension wrapped in a microporous PTFE dielectric. An advanced continuous screen with a copper shielding braid ensures minimal RF interference and noise susceptibility.\u003c\/p\u003e\n\u003cp\u003eIn our ‘dd’ (dual-drain) configuration, twin symmetrical drain wires connect the screen to the cable return\/plug interface, allowing cable termination without distorting, twisting or mechanically stressing the precision-laid screen. Typically, screened cables suffer from screen distortion when prepared for production. Cutting and twisting the screening braid has a measurable impact, effectively changing the impedance and, therefore, the cable’s performance. Using tools we created for this specific task, our precisely calibrated build process maintains the required conductor geometry and ensures the highest level of manufacturing consistency and reliability.\u003c\/p\u003e\n\u003cp\u003eTermination is with our latest generation innovative ultra-low-mass ‘Ultra L’ (Latik) RCA which uses a 3D printed liner component and cold-weld connection. In a cold-weld (solder-free) connection, the metal of the connector plug and the wire are squeezed together under a calibrated pressure to form a robust, consistent, air-tight metal to metal contact with no deformation of the cable dielectric. The result is a smooth, uninterrupted signal path which behaves as one continuous entity.\u003c\/p\u003e\n\u003ctable class=\"specifications ruled\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eTwin Multi-core dd (dual drain)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eOCC Copper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDielectric\u003c\/td\u003e\n\u003ctd\u003eMicroporous PTFE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScreen\u003c\/td\u003e\n\u003ctd\u003eBraid + Mylar™, 100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e71.17 pF\/m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInductance\u003c\/td\u003e\n\u003ctd\u003e0.332 µH\/m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance\u003c\/td\u003e\n\u003ctd\u003e0.0197 Ohm\/m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutside Diameter\u003c\/td\u003e\n\u003ctd\u003e9.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eIncorporates Atlas’ Grun Coherent Earthing System connector (basic adapter included).\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"235\" width=\"579\" src=\"https:\/\/www.atlascables.com\/assets\/images-featured\/hero-grun-panel-mavros.jpg\" data-mce-src=\"https:\/\/www.atlascables.com\/assets\/images-featured\/hero-grun-panel-mavros.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrun Coherent Earthing System\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe benefit of an independent system earth.\u003cbr\u003eOne of the biggest obstacles to achieving the performance levels our equipment is capable of is noise. Low levels of RFI (radio frequency) and EMI (electro-magnetic interference) and noise on the signal ground all subtly modulate and degrade the overall noise levels of the system.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eIronically, this is generally only noticeable when eliminated – even though much of this ‘noise’ is theoretically at frequencies beyond the range of our hearing. The main sources are noise in the mains supply and component ground connections – mobile phones, ‘wallwart’ chargers and wifi networks are major offenders – while a percentage is actually generated within the equipment itself. Generally things have got worse with the advent of computer audio.\u003cbr\u003e\u003cbr\u003eThe Grun Coherent Earthing System addresses these issues by providing an ‘independent’ earth for users of Mavros, Arran and Asimi Ultra interconnects.\u003c\/p\u003e\n\u003cp\u003e*Speaker cables are part of low impedance circuits and as such are not as susceptible to electrical interference as analogue interconnects. However, speaker cables often radiate interference, consequently it is good practice to ground the screen if available to minimise any ‘antenna’ affects.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eGrun interconnects are easily identified by the blue-green Ultra RCAs (interconnects) and ‘flying’ earth connectors.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0376\/5026\/8291\/files\/grun_1024x1024.png?v=1686161579\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"content columns cC2 vP2\" data-mce-fragment=\"1\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"content columns cC2 vP2\" data-mce-fragment=\"1\"\u003e\u003c\/div\u003e","brand":"ATLAS","offers":[{"title":"0.5m","offer_id":56215708336514,"sku":null,"price":1800.0,"currency_code":"GBP","in_stock":true},{"title":"0.75m","offer_id":56215708369282,"sku":null,"price":2075.0,"currency_code":"GBP","in_stock":true},{"title":"1.0m","offer_id":56215708402050,"sku":null,"price":2350.0,"currency_code":"GBP","in_stock":true},{"title":"1.5m","offer_id":56215708434818,"sku":null,"price":2900.0,"currency_code":"GBP","in_stock":true},{"title":"2.0m","offer_id":56215708467586,"sku":null,"price":3450.0,"currency_code":"GBP","in_stock":true},{"title":"3.0m","offer_id":56215708500354,"sku":null,"price":4550.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/6652\/0962\/files\/arran-ultra-rca-grun-plugs.jpg?v=1768428415","url":"https:\/\/premiumhomeaudio.co.uk\/products\/atlas-cables-arran-rca-pair","provider":"Premium Home Audio","version":"1.0","type":"link"}
