Mavros Ultra RCA interconnect wins HiFi News ‘Product of the Year’ Award
Our latest generation Mavros Ultra and Asimi Ultra interconnects and Mavros speaker cables with ‘Grun’ compatibility offer a further step forward with clear performance gains (the cable specification is otherwise unchanged).
*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.
Grun interconnects are easily identified by the blue-green Ultra RCAs (interconnects) and ‘flying’ earth connectors.
Asimi/Mavros Ultra Factory Upgrade
The great news for existing owners of the Ultra versions of the Asimi and Mavros interconnects is that can be factory upgraded to incorporate the Grun Coherent Earthing System. Please contact Atlas direct for more information.
Getting Started: Basic Configuration
Mavros and Asimi interconnects are now configured with a flying ground lead on each channel. A basic Grun adapter is supplied as standard with these cables, and should typically be connected to a spare RCA input socket on your amplifier.

Why ‘earth’ a speaker cable?
Generally speaking, loudspeaker cables don’t potentially pickup interference in the same manner as an interconnect, but they may ‘broadcast’ interference, effectively acting as an antenna. In today’s extremely (electrically) noisy world, it’s important to minimise the adverse effects of noise on system performance – this can be addressed very effectively by providing a grounded screen on the cables.
Mavros speaker cables are now configured with a flying ground lead on each cable. Grun termination should be made to the amplifier’s ground terminal via 1–1 (×2) or 2–1 spade adapters.
Add an Adapter: Optimum Configuration
The preferred configuration is to create a direct ground, either to the ground terminal on your amplifier (if fitted) or via a Grun mains adapter to a spare socket on your mains distribution block.
Please not that the Atlas Grun topology is intended for audio signal earth only. Grun products are not to be used as a replacement for the ‘safety earth’ facilitated by the original equipment manufacturer and in no circumstances should you use these connections for sole earthing of any type of equipment connected to the mains power supply.
