Ver. 1.0
Optional PS2-S Phono Module
Gain:
Moving Coil (MC) 64dB
Moving Magnet (MM) 42dB
Impedance:
Moving Coil (MC) 20, 100, 200, 499 and 806 Ohm – or custom load
Moving Magnet (MM) 47 kOhm/200pF
S/N ratio:
MC, Input 250mV, 1kHz: >72dB
MM, Input 2.5mV, 1kHz: >84dB
Input impedance in MC mode
Fit the desired load jumpers on pinheaders JP101 and JP301.
It is not recommend to use the module in MC mode without load jumpers.
Recommended max. custom load: 1kOhm. Default factory fitted jumpers: 100 Ohm
Input impedance in MM mode: The input impedance in MM mode is 47kOhm/200pF
Switching between MM and MC
The selection of MC or MM is made with jumpers JP100, JP102, JP104, JP300, JP302, and JP304
100 ohm
