iFiiPhonoUser4StepGuide



Step1:ConnectMM/MCInput.

Refertothecartridgemanualforthespecifiedoutputvoltage.

Eg: TheoutputvoltageoftheMCcartridgeDenonDL‐103Ris0.25mV;

TheoutputvoltageofatheMMcartridgeShureM97xEis4mV.



e.g.ShureM97xE(4mV)shouldbeconnectedtotheMMinputoftheiPhono;

DenonDL‐103R(0.25mV)shouldbeconnectedtotheMCinputoftheiPhono.



Note:MMandMCinputsshouldNOTbeconnectedsimultaneously.



Tip:ForrareHighOutputMCcartridgesliketheOrtofonMC‐3Turbo

，

itsoutputis3.3mV

，

soit

shouldbeconnectedtotheMMinputoftheiPhono.Theactualoutputvoltagedeterminatewhich

inputshouldbeused.



Tip:Remembertoconnectthegroundwirefromtheturntable/armtotheiPhono.

Usethesmallextensionleadincludedforeaseofconnection.Sofullvinylsystemis

nowfullygroundedtogether.



Step2:SetGain.



Allphonopre‐amplifiershavegainadjustment.Differentcartridgesrequiredifferentlevels

ofgain.



MMcartridgesrequirelowergainandMCcartridgerequirehighergain.Normallygainis

expressedindecibel(dB),40dBmeans100timesgain.



CartridgesOutput GainRequired

>3mV40dB

1mV‐3mV46dB

0.3‐1mV 60dB

<0.3mV66dB



Fromtheabovetable,ShureM97xEshoulduse40dBgain,andDenonDL‐103Rshoulduse

66dBgain.

Aslongastherightconnection(MM/MC)ismadeasper“Step1:ConnectMM/MCInput”,

thereisnoneedtodistinguishMM/MCcartridgeanymoreforthefollowingsteps.



(i) Pleaselookattheoutputvoltageofthecartridge;

(ii) Determinatethegainrequired(dB)fromtheabovetable;

(iii) Thenjustsetthemicroswitchesexactlyasfollows,ignorethegrayedout

switchesfornow.

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.

Theleft‐mostcolumnoftheloadtableistheactualloadvalue:



Forexample：

250Ω（MC）47kΩ（MC）

Iftherequiredloadvalueis250Ω,thenthe

4microswitches330Ωand1kΩshallbe

inthe“●”(right)position;othermicro

switchesshallbeinthe“‐“(left)position.

Iftherequiredloadvalueis47kΩ,all

microswitchesshallbeinthe“‐“(left)

position.

Iftherequiredloadvalueis400pF，then

shallbeinthe“●”(right)position;other

microswitchesshallbeinthe“‐“(left)

position.

Iftherequiredloadvalueis100pF,allmicro

switchesshallbeinthe“‐“(left)position.

Note:Forhighoutputcartridge,pleaseusetheMMcartridge(pF)settings.

Tip:Typically,MCcartridgesofferthebestsound,MMcartridgesaremosteconomical,Highoutput

MCcartridgesaresomewhereinbetween.

Step4:SetEQcurve.

Forthecorrectplaybackofeachandeveryrecord,thecorrectEQcurvemustbeused.There

aretwosmallstepstosetthiscorrectly.



1：RIAA/eRIAA/IEC

(Undernormalcircumstance,onecanjustleavethisunchangedasitis

partofthefactoryDefaultsettings)



2:DECCA/RIAA/COLUMBIA



Atthebeginning,thereusedtobemanydifferent

kindsofEQcurve.In1954,Recordlabelsalloverthe

worldagreedtouseasingleRIAAEQcurveforall

records.However,therealityisthatonlyafter1980s,

allrecordsareactuallyusingRIAAEQcurves(justthink,

howeasyisittoreachasingleagreementonaglobal

scale?Andimplementitovertheshortspaceof1‐2years?).



IfthewrongEQcurveisused,therecordwillnotsound“right.”Forexample:Deutsche

Grammophon’sclassicalrecordsreleasedbefore1980oftensounddryandflat,thereasonis

becausethoseweremanufacturedusingtheDECCAEQcurve,nottheRIAAEQcurve.



Recordreleasedbefore1980:

RecordLabelsiPhonofrontEQswitch





RIAA(Middle)





DECCA(Down)



Note:ForEMIrecordsissuedinEurope,manyofthemwereusingtheDECCAEQcurve.For

EMIrecordsissuedintheUSA,manyofthemwereusingtheCOLUMBIAEQcurve,especially

theoneswhichwereoriginallyproducedbyCOLUMBIA/CBSbutissuedundertheEMIlabel

afterthemerger.



Forrecordsissuedafter1980,mostofthemareusingthestandardRIAAEQcurve.

Wehopethistutorialhashelpedyoufindmorelifeinyourvinylcollectionandultimately,

leadtoanevengreaterlevelofmusicalenjoyment!
