CARTRIDGE LOADING – RESISTIVE
For MC cartridges, the maximum resistive load is 1,000Ω. This is
the value when there is no resistor added to the Personality Card. This
value may be lowered by adding a resistor (as shown) at R1 whose
value is calculated by the following:
R1 = 1/(1/R

Some typical values are:
Desired R (Ω) R1 (Ω)
50 52.3
100 110
200 249
500 1,000
For MM cartridges, the maximum resistive load is 47kΩ. This is
the value when there is no resistor added to the Personality Card. This
value may be lowered by adding a resistor (as shown) at R1 whose
value is calculated by the following:
R1 = 1/(1/R
