ATLAS Alisa Duo Ultra L RCA Grun interconnect

Atlas Alisa RCA Duo Grun Analogue Interconnect

Atlas Alisa RCA Duo Grun is a wide-bandwidth solid-core RCA interconnect utilising the new 'Duo' independent dual-drain screen topology, a further refinement of Atlas' proven 'dd' dual-drain system, defining a new performance level for the Alisa range.

Designed to overcome the shortcomings of conventional coaxial cables, the Alisa Duo features two separate, independently-screened solid-core OCC copper conductors for the 'hot' (+) and 'cold' (-) connections, enhancing rejection of unwanted signal-degrading noise.

Solid-core construction offers significant improvements over multi-strand conductors, with lower distortion and greater consistency in performance.

Key Features

• 'Duo' topology – two separate, independently screened signal conductors.
• Solid-core OCC copper conductors for both 'hot' (+) and 'cold' (-) connections.
• Independent dual-drain screening for enhanced rejection of signal-degrading noise.
• Precision-twisted assembly – further increases rejection of RF and EM interference.
• Ultra L (Latik) RCA connectors featuring a low-mass design and non-conductive 3D-printed geometric lattice structure.
• OCC copper connector pins – the same grade of OCC copper as the conductors.
• Solder-free cold-weld connection for excellent signal continuity.
• Grun Coherent Earthing System – further lowers the system noise floor.
• Neutral, detailed and engaging presentation without artifice or exaggeration.

Ultra L (Latik) RCA Connectors

The Alisa Duo uses Atlas' acclaimed, low-mass Ultra L (Latik) RCA plugs. These benefit from an innovative and extremely stable non-conductive 3D-printed geometric lattice structure, designed to have minimal impact on the delicate signal.

The connector pins use the same grade of OCC copper as the conductors. Combined with Atlas' solder-free cold-weld connection method, this ensures excellent signal continuity.

Advanced Noise Rejection

The cable uses a precision-twisted assembly to further increase rejection of RF and EM interference. Combined with the Duo topology, this creates a cable which Atlas describes as offering clear performance gains, with elements of the coherence and tonal accuracy found in its High End Mavros and Arran products.

The latest generation Alisa delivers a neutral, detailed but engaging presentation without artifice or exaggeration, offering fresh insight into both new and familiar music.

Grun Coherent Earthing System

Performance, particularly with regard to increasing dynamic range by lowering the system noise floor, is further enhanced by the Atlas Grun Coherent Earthing System.

A Grun lead and spade adapter are included with the cable.
