Any suggestions for dip-switch settings for this setup?
Many Thanks!

Hi, dll,That chart at AudioKarma was the first version I created but it didn't include my name, the model of JD9 that it references, or that some settings are undocumented. An updated chart for the 2006 model is available here: https://gallery.audioasylum.com/cgi/view.mpl?u=32746&f=jolida_jd9_settings1.jpg&v=f&User...

The newer JD9 II has been modified somewhat from the original version but I'm not sure what differences (other than cosmetics) are involved. Jolida does not appear to include specific information on gain settings in their manual

For mccrea60,
Ortofon provides information for the 2M Black on their website:
- Output voltage at 1000 Hz, 5cm/sec. - 5 mV
- Recommended load resistance - 47 kOhm
- Recommended load capacitance - 150-300 pF
Based on those specifications I'd start with these settings:
- Low output (MM) connections, gain set to ~50 dB
- Impedance/resistance set to 47,000 Ohms
- Capacitance set to 150 picoFareds
