BOTHERED by external electrical noise finding its way into your hi-fi system? The Chord Company offers you solutions with its PowerARAY and PowerARAY Professional noise-suppression devices that are designed to reduce the less-than-salubrious affects.
Operating in parallel to the power with no current flowing through, PowerARAY technology “has been designed to reduce high-frequency noise as much as possible and provide a consistent and worthwhile improvement to the mains supply just before entering hi-fi systems… parallel filtering is applied to the live, neutral and earth, and has been optimised to reduce noise,” according to the company.
The PowerARAY plug-type device directly connects to unused mains power sockets, either on walls or distribution blocks, adjacent to sockets used to power audio systems, and “provides a low-impedance ‘escape route’ for high-frequency noise, therefore reducing the amount of noise entering the system, lowering the noise floor and allowing more room for the music.”
The costlier PowerARAY Professional has the same application principles, but “takes performance to the next level, deploying a separate, larger capacity case with damping isolation feet, and connected via a high-performance captive power cable.” The power cable options are from Chord Company’s premium Signature, Sarum or ChordMusic collections.
“PowerARAY Professional draws on technologies developed for Chord Company’s proprietary SuperARAY and GroundARAY products, and similarly, operates in parallel with the electricity supply: it does not get between the electricity supply and equipment. This approach ensures wide-ranging flexibility across all manner of audio systems and power supplies etc.”
The device “targets HF noise by introducing a potential gradient that turns noise into heat. Inside, the internal earth, live and neutral parts benefit from connection to their own MainsARAYs, plus individual (no-compromise) SuperARAYs.”
All other internal parts are securely held in place by machined aluminium billet, with internal components enveloped by a special damping resin. Both the PowerARAY and PowerARAY Professional can be used alongside other Chord Company proprietary ARAY products to compound hi-fi performance.
PowerARAY retails for £550 and PowerARAY Professional for £5,500 (with SignatureX power cable)/ £6,000 (SarumT)/£7,000 (ChordMusic). Both are available with UK, Euro (Shuko) or US connections.
