Ortofon 2M Blue Cartridge
The 2M Blue features a nude elliptical diamond and all styli within the 2M range are interchangable so when replacement time arrives it is possible to also upgrade by fitting the next model up in the range.
To obtain a flat frequency response as with a Moving Coil cartridge we are using the slit pole pins to reduce the eddy current. The slit pole pins is an Ortofon invention which was presented in the 500 series and the Super OM series. The 2M Blue and 2M Red both have the same engine with slit pole pins. With this improved engine we have been able to increase to output to 5,5 mV.
The cartridge body used for the 2M Bronze and 2M Black is manufactured from a newly-developed Noryl plastic/glass combination, a revolutionary material which ensures high rigidity while eliminating unwanted resonances. The 2M Bronze and 2M Black use a special upgraded engine, featuring split pole pins with a silver plated copper wire.
