Atmosphere Series AC Power Cords, a new line of AC Power Cords from Synergistic Research, featuring the world’s first use of Graphene which has the highest current density in the world of any material (8 million times that of copper) making it a near “superconductor” at room temperature!

Graphene imparts performance characteristics not found in any other power cables. The new Atmosphere AC cords also include built-in UEF filters and internal power supplies for Active Shield biasing of the cable WITHOUT the need for an external power supply. Simply plug and play like conventional passive power cords. These AC cords are flexible and thinner than the models they replace.

Level 3 Digital

Digital components create noise that analog components do not and this noise should to be eliminated before it contaminates your system. Atmosphere Level 3 Digital AC Power Cables are specifically designed to reduce digital noise by shunting it to ground inductively through Active Shielding and through a special multi-geometry voiced for digital components. The same Swiss-Made power supply found in our Galileo UEF power cords is the driving force for Atmosphere Level 3’s onboard Active Shielding which has a more refined sound than does the more conventional power supply found in Level 2. Level 3’s geometry also get’s a boost from one additional pure Silver Air String for a sound that has more air and finesse. Custom tuning is achieved through the use of a Gold UEF Tuning Module that adds warmth and bloom or when not connected the cable has a leaner balance. Of course, the choice of whether or not to use the Tuning Module is yours, giving you the power to take control of your system.

UEF Cell

Swiss made power supply

Each Atmosphere Level 3 Power Cable contains a Swiss-made power supply and Quantum capacitors to generates the 30 Volt DC bias necessary for Active Shielding, eliminating the need for messy external wiring and cumbersome wall warts. Performance is further enhanced by the introduction of UEF technology built into the power supply and cable shielding for an incredibly low noise floor.

Red and Gold Tuning

Redefining refinement

The Atmosphere Level 3 Power Cables active shielding is voiced with a single Red UEF Active Circuit. Also, included is a Gold, passive UEF Tuning Module. The UEF Tuning Module is connected to the cable shields and contours the sound of your cables by changing the way your cables resonate. By altering the resonance between signal and ground conductors you take control of the sonic balance of your cables and in the process, the overall sound of your system.

The Red Active Circuit completes the Active circuit and must be in place in order to achieve the highest performance.

     Build Notes:

    • 32 point-to-point hand soldered connections
    • Atmosphere UEF 4 Treatment: 2 different UEF coatings with Graphene are applied at a higher level to the UEF Active Cell, Quantum Capacitor, connectors, cabling and ground significantly reducing the noise floor and allowing a purer signal to transfer with less grain providing more warmth and detail. The conductors and ground plane and UEF Cell also benefit from dampening effect that UEF provides
    • 1 Termination for Atmosphere Active Tuning Module (Red)

    • 1 Termination for Atmosphere UEF Passive Tuning Module (Gold)
    • Silver Solder: 4%
    • Hand build time: 2.5 hours
    • Quantum Tunneling: Before the Active power supply is incorporated all connections and cabling are treated with 1,000,000 volts of electricity at specific frequencies and pulse modulations, creating a canal in the conductor material and contact points at the molecular level that lets electrons to flow more freely. This also allows the "Active Shielding" to work more efficiently yielding the maximum amount of low level information through the conductors and provides for the highest amount of realism in your music
