LAB12 melto2 - Remote Controlled, Fully Adjustable Phono PreamplifierPage 10 of 124. Equalizer CurveYou can choose between 3 available de-emphasis curves: RIAA, Decca and Columbia to adjust the frequencyresponse of melto2 output.Each record provides the emphasis curve that has been used while it was being produced, but you can tryalternative curves in any record without problem.In a simple description:Decca offers higher gain on high frequencies and lower in low frequencies compared with RIAA.Columbia offers lower gain on high frequencies and higher in low frequencies compared with RIAA.Input Impedance and Capacitance also affect the balance of the frequency response.5. CapacitanceFor the MM cartridges, you can choose the desirable Input Capacitance. Try values near cartridge manufacturer’srecommended value to ‘’flatten’’ the response and avoid resonant peaks in higher frequencies. However, thecapacitance values are affected from the cartridge’s design philosophy, as well as from the connecting cables, sothere is no absolutely correct setting. Therefore, experimentation is recommended until you find a setting thatsuits your set-up and personal preference.For the MC Cartridges, the setting is locked to the lower value.
