From a review:
"The voltage gain of the MC section is variable, as it’s able to be switched between an indicated 22dB, 26dB, 28dB and 32dB. However, because the MC section includes a fixed gain stage with a voltage gain of 40dB, the actual gains are 62dB, 66dB, 68dB and 72dB. When you switch gain on the MC section, you also necessarily switch input impedances, which Allnic confusingly labels as ×13, ×20, ×26 and ×40, stating only that the highest input impedance the MC section offers is 280Ω. In fact, according to Kang Su Park, the corresponding impedances are 29Ω, 69Ω, 117Ω and 278Ω. In each case these are suitable for cartridges ‘up to 29Ω,’ ‘up to 69Ω’, ‘up to 117Ω’ and ‘up to 278Ω’." That should answer your question regarding the use of MC cartridges.
Without spending more time (5 minutes so far), the MM section is likely to present a standard 47K ohm load. The forte of this unit is probably to use it with MC cartridges.
