We all know that record spins at (let's take at this point) 33.5 rpm and while the rotational speed is the same the speed of the actual groove is not. Our cartridges are specked at output voltage for a specific speed of the grove(cm/c). What happens when a)the speed is higher than specified at outer grooves b)the speed is lower than specified at inner grooves c)the record spins at 45rpm or 78rpm
Thanks for joining this discussion! Would you consider a decreased performance on the inner groves normal in some of records especially fully "packed"?
