Step1:ConnectMM/MCInput.
Refertothecartridgemanualforthespecifiedoutputvoltage.
Eg: TheoutputvoltageoftheMCcartridgeDenonDL‐103Ris0.25mV;
TheoutputvoltageofatheMMcartridgeShureM97xEis4mV.
e.g.ShureM97xE(4mV)shouldbeconnectedtotheMMinputoftheiPhono;
DenonDL‐103R(0.25mV)shouldbeconnectedtotheMCinputoftheiPhono.
Note:MMandMCinputsshouldNOTbeconnectedsimultaneously.
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
inputshouldbeused.

Step2:SetGain.
Allphonopre‐amplifiershavegainadjustment.Differentcartridgesrequire differentlevels
ofgain.
MM cartridges require lower gain and MC cartridge require higher gain.Normally gain is
expressedindecibel(dB),40dBmeans100timesgain.
CartridgesOutput GainRequired
>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
66dBgain.
