To find out which type your cartridge is, please consult the literature accompanying your cartridge.
The literature for cartridges should also specify the correct input impedance (low-output MC
cartridges) and the correct input capacitance (high-output MC and MM cartridges), into which the
cartridge is designed to work. If in doubt please consult your dealer.
