Step 3: Set Load.
Each and every cartridge requires the correct load to sound its best. MM cartridges require
capacitive load (pF), MC cartridges require resistive load ( Ω /Ohm).
The correct load value shall be stated in the cartridge manual too, however not ALL
cartridges state this value.
Many people have misunderstood this load value as the same as the cartridge internal
impedance/resistance which is incorrect.
Cartridge Impedance/Resistance Correct Load
Shure M97xE
（
MM
）
1550 Ohm 200 ‐ 300pF
Ortofon MC ‐ 3 Turbo
（
High Output MC
）
100 Ohm 47kOhm
Denon DL ‐ 103R
（
MC
）
14 Ohm Not Stated.
For cartridges that have no load value stated in the manual, the only way to find out the
correct load value is by listening. Which load value provides the most natural sound, then it
is the right value. For example, the correct load for Denon DL ‐ 103Ris around 1kOhm.
Tip: If the sound is too dull, try increasing the pF(MM)or Ω /Ohm(MC) value
；
if the sound is
too bright, try lowering the pF(MM) or Ω /Ohm(MC) value.
The upper ‐ most row of the load table is the name of the micro switches, corresponding to
the actual micro switches on the left:
