With 40 years of experience in minimizing the impact of external interference in audio systems, Chord Company is expanding its GroundARAY and PowerARAY<\/a> noise reduction lines to now include PhonoARAY<\/strong> for use with turntables.<\/p>\n\n\n\n

PhonoARAY is a standalone filtering solution that allows turntable users to earth\/ground their devices to the phono stage, or the phono input on amplifiers, providing maximum protection for the highly sensitive signal.<\/p>\n\n\n\n

The PhonoARAY is housed in a thick-walled machined aluminum casing designed to provide electrical and acoustic isolation. Its chamber is resin-filled to reduce microphony, which is when mechanical vibrations are transformed into an undesired electrical signal\/noise.<\/p>\n\n\n\n

PhonoARAY incorporates a hand-wound, ultra-high-current series filter for both terminals together, plus a proprietary ARAY system, connected in parallel. This creates a double \u2018virtual earth system\u2019 for both the turntable and phono stage. This combination is designed to shield sensitive signals from external interference for cleaner and more detailed sound reproduction.<\/p>\n\n\n\n

The PhonoARAY connects via two 4 mm speaker-style banana or spade connectors between the earth terminal of the turntable (or tonearm) to the earth terminal of the phono stage (or amplifier phono input) using a dedicated high-quality 50 cm screened earth cable (4 mm connector to spade connector).<\/p>\n\n\n\n

The phono can be used in a variety of turntable configurations, including turntables with or without built-in phono stages. In systems with external phono stages, a second PhonoARAY can also be added, additionally connecting the phono stage earth to the amplifier earth.<\/p>\n\n\n\n

The PhonoARAY benefits from a thick-walled enclosure machined from a solid aluminum billet, providing excellent electrical and acoustic isolation. Additionally, resin filling within the enclosure further reduces microphony, while lightweight, decoupled isolation feet minimize vibrations.<\/p>\n\n\n\n
