Ringmat Platter Insert
For use with Roksan Xerxes and similar platters, the lower section of the platter inserts comprises a 3mm foam rubber disc and the upper section a 1.6mm disc of neoprene foam sponge. Both discs have a diameter of 124mm and a centre hole of 4.5mm to go over the small 4mm Roksan spindle. To use the inserts, place the thicker 3mm insert over the spindle so that it rests in the centre of the inner platter/hub. Place the thinner 1.6mm insert on top of the thicker one. Although it is not possible to visually distinguish one side from the other, it may be found that the sonic performance of each insert is different according to which way up it is used. Accordingly, some experimentation may be worthwhile.
For use with Garrard 401 and similar platters, the platter insert comprises a single 1.6mm disc of neoprene foam sponge with a diameter of 124mm and a centre hole to go over a standard 7mm spindle. As in the case of the Roksan inserts, it may be found that the sonic performance of the Garrard insert varies according to which way up it is used. Accordingly, some experimentation may be worthwhile.
