Chord Company GroundARAY Noise Reduction Device
The GroundARAY is a next-generation high-frequency-noise-reduction device that connects to unused sockets on A/V equipment providing a low-impedance route for HF noise to pass through, directly improving the noise floor of the ‘host’ product.
The GroundARAY is a cylindrical design made from precision CNC-machined thick-walled aluminium; the thick walls themselves stop the device from contributing HF noise. Available in six termination options, including USB A, RCA and XLR, for a wide range of digital and analogue A/V devices, the GroundARAY benefits from five separate noise-reduction systems, all working across different HF noise ranges and operating in parallel to convert undesirable HF electrical noise into heat.
The advanced technologies provide a very low-impedance, high-bandwidth route for HF noise to pass into, effectively ‘pulling’ noise from the signal ground of the host equipment.
GroundARAY: built from the ground up
Each GroundARAY is painstakingly built by hand at Chord Company’s Wiltshire factory, including the system components themselves. The GroundARAY comprises a number of absorption devices, attached with a highly advanced double ultra-high-bandwidth connector system. The connectors are made to a very high standard, demanding time-consuming hand-assembly by factory technicians.
Each GroundARAY cylinder is filled with a carefully chosen material to deaden noise. The final assembly is then locked into place to reduce any effects from acoustic vibration.
GroundARAYs are most effective when used across several devices in an A/V 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, GroundARAYs can be used with unused digital inputs; projectors and screens can also benefit from the noise-reduction effects, too.
