*placement specifications assume a 55mm distance from back of headshell to stylus. This value may vary by approximately +/- 6mm depending on cartridge type and cantilever length
Mounting Surface to Platter distance
The Rigid Float tonearm is designed to operate best when placed on a surface that is approximately 45mm to 65mm lower than the top of your platter. This value may vary by +/- 3mm depending on cartridge height dimensions. For turntables without sufficient platter to surface distance, outboard placement of the tonearm is recommended.
