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.



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.
