PhonoARAY turntable earthing system

The PhonoARAY was conceived to improve the playback of turntables, although it can be used successfully in a variety of earthing applications within an audio system. Turntables can be earthed to the phono stage or phono amp input, whilst providing maximum protection for the highly sensitive signal.

Inside the PhonoARAY is a hand-wound, ultra-high-current series filter, joining both terminals, as well as a complex ARAY system, connected in parallel, that gives added sound security and also provides an effective double “virtual earth system” for both the turntable and phono stage.

Connections on the PhonoARAY are via two high-quality 4mm speaker-style terminals, accepting 4mm ‘banana’ and spade connections.

The PhonoARAY connects the earth terminal of the turntable (or tonearm) to the earth terminal of the phono stage (or amplifier phono input) and is supplied with a dedicated 50cm screened earth cable (4mm to spade connector) to be used between the PhonoARAY and the phono input earth.

The PhonoARAY is housed in a thick-walled machined aluminium billet to provide good electrical and acoustic isolation. The PhonoARAY chamber has been resin-filled to reduce microphony, which is when mechanical vibrations are transformed into an undesired electrical signal/noise.

The casing rests on two extremely lightweight, decoupled isolation feet to further reduce microphony. The feet fixing bolts should be loosened before installation to allow full decoupling.
