Mobility Fidelity Sound Lab's Geo-Disc is the perfect complement to its series of limited edition original master recordings. Both will markedly improve the sonic performance of your stereo playback system. The high fidelity pleasures of original master recordings, even the audio content of conventional records, cannot be totally realized in your phonograph pickup apparatus (stylus / cartridge) if it is not aligned accurately. This is where the Geo-Disc is essential.

With extensive research and development, the Geo-Disc features a proprietary 3D visual system that delivers incredibly precise, uncomplicated, rapid and economical cartridge alignment. Mobile Fidelity's Geo-Disc is an LP sized platter that provides a very accurate spot for adjusting the cartridge overhang, and has visual gridlines for properly adjusting the offset angles. It's a lot easier to use than those flimsy plastic templates or paper cutouts that come with a lot of turntables. Just fit the disc on your platter and align using the simple printed graph based on the Baerwald alignment curve.
