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. PowerARAY provides a low-impedance ‘escape route’ for high-frequency (HF) noise, therefore reducing the amount of noise entering the system, lowering the noise floor and allowing more room for the music. It is available with UK, Euro (Shuko) or US connections.
