The ultimate in MM cartridge versatility, the Super OM series all have the same cartridge body, internal structure and magnetic circuitry, the only difference between models are the interchangeable styli. With a standard Elliptical stylus, the OM-10 offers performance to suit any budget. All Super OM cartridges weigh only 5 Gms and have 4mV output. Each one features Ortofon's special 'cut-out' nose that makes accurate record cuing a snap while reducing stylus and record damage.Output voltage: 4 mV Channel balance: 1.5 dB Channel separation at 1 kHz: 22 dB Frequency response (Hz): 20-20k (+3/-1dB) Stylus type: Elliptical Stylus tip radius: r/R 8/18 µm Equivalent stylus tip mass: 0.5 mg Tracking force range: 1.25-1.75 g Recommended Tracking force: 1.5Gm Tracking angle: 20° Internal impedance: 1 kOhm Internal inductance: 580 mH Recommended resistance: 47 kOhm Recommended capacitance: 200-400 pF Cartridge weight: 5 g
