CARTRIDGE LOADING – RESISTIVE
For MC cartridges, the maximum resistive load is 1,000 Ohms. 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/RDESIRED – .001)
Some typical values are:
Desired R (Ω) R1 (Ω)
50 52.3
100 110
200 249
500 1,000
