GroundARAY

GroundARAY is a companion device that connects to unused sockets on hi-fi or AV equipment, providing a low-impedance, high-bandwidth route from the signal ground of the host equipment, converting undesirable noise into heat.

GroundARAY benefits from five separate systems, all working across different frequency ranges and operating in parallel. Each unit is constructed by hand at our Wiltshire HQ. The casing is made from precision CNC-machined thick-walled aluminium and contains a number of absorption devices, attached with a highly advanced double ultra-high-bandwidth connector system. After construction, each GroundARAY cylinder is filled with a compound to deaden noise and reduce acoustic vibration.

GroundARAYs are most effective when used across several devices in a system. The devices simply plug into existing empty sockets and can be used individually, or in multiples, such as across left and right outputs etc. With DACs and streamers, GroundARAY can connect to unused digital inputs.

Available in multiple termination options, including USB A, RCA, DIN, XLR, BNC, RJ45, HDMI, for a wide range of digital and analogue devices.

Demo sets are available from participating Chord Company retailers.

GroundARAY development background

For years, Chord Company has been developing proprietary technologies to reduce both low- and especially high-frequency noise, many of which, such as shielding, can be found in its cable ranges today.

In 2012, Chord Company introduced a solution to reduce damaging HF noise present in the equipment itself: the company’s proprietary TunedARAY mechanical tuning system. Successive and more advanced variations, such as SuperARAY followed, but the ARAY designs were always specific to the cable they were working with, limiting the technology due to space and other design factors.
In 2017, Chord Company started to prototype a next-generation ARAY system, one that would work over the widest range of high frequencies possible, with very high efficiency. This ARAY was designed from the ground up, without any of the limitations imposed with cable design.

The next-generation ARAY system was designed to operate independently from cables, but work with them in helping to reduce HF noise on the signal ground. This new group of devices became known as GroundARAYs and in order to work with different types of A/V equipment, needed to have a selection of different plug adaptors: RCA; DIN; BNC; RJ45; USB Type-A and XLR male and female.

Product review: Chord Company GroundARAY - Hi-Fi+ 207 May 2022

“The logical place to go looking for sonic differences would be the noise floor, and yes, those silences are some of the most silent silences I’ve never heard.” HI-FI+

Product review: Chord Company GroundARAY - The Audio Beat August 2021

“..inserting an RJ45-equipped GroundARAY into an unused socket on the switch didn’t just snap high-res files into focus; it brought a welcome sense of stability and presence to the replay, significantly narrowing the normally all-too-obvious gap to physical media. For all computer audiophiles out there, this is a must-try upgrade. If you are running a...
