Designed as a direct replacement for the supplied platter mat of many high quality turntables, this mat is the result of many years of research and is a felt and cloth sandwich construction of uniform thickness. It provides a precise support of the record on the platter whilst protecting the groove from damage that can be sustained using a hard surface such as glass or metal.
If replacing a thick rubber or felt mat, the stylus VTA (Vertical Tracking Angle) may need adjustment. If used with a Linn turntable, the process of ‘clocking’ the platter may be beneficial. Please see these articles about Adjusting the VTA and Clocking the Platter on Linn LP 12s by clicking the links.
