POWERARAY PROFESSIONAL (SARUMT 80CM) EU

Chord Company PowerARAY — mains noise-reduction device; plug into a spare socket to lower the noise floor.

Technical background

Chord Company's ARAY noise-reduction products — GroundARAY and PowerARAY — are entirely passive devices that use proprietary conductor geometry to dissipate high-frequency noise when plugged into an unused input, output or mains socket. They contain no active components, require no power and introduce no alteration to the signal path. They work by providing high-frequency interference a controlled low-impedance dissipation path without creating a feedback loop or ground loop. The ChordOhmic GroundARAY is available in RCA, XLR, BNC, USB-A, USB-B, RJ45 and DIN formats to cover every unused digital and analogue input in a modern streaming and analogue hi-fi system.

Design story

The GroundARAY and PowerARAY products emerged from Chord Company's long-running investigation into why hi-fi systems perform differently on different days and in different properties. The answer they identified was mains and earth-path borne high-frequency noise — interference that never appears on standard power supply specifications but measurably affects the noise floor of sensitive audio equipment. The passive ARAY conductor geometry, when terminated into an unused input or mains socket, provides a clean dissipation path for this noise without creating ground loops or signal path alterations — a solution so effective that it has become one of the most widely recommended accessories in the high-end audio trade.
