Jolida JD-9 phono pre-amp dip switch settings

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

Don't forget to add in the capacitance of the phono cables. The phono pre is seeing both the cable and cartridge capacitance. Beyond that you should set it by ear after picking your starting point. BTW, even though it is not stated by Jolida, the capacitance setting of the JD-9 can be set to zero (I confirmed this with Jolida in the past). A cart such as one of the Clearaudio ebony wood series that have a spec. of 100pf would need a setting from zero to 100pf depending on personal preference. The cables won't be zero and hopefully will be less than 100pf.

That's right Tom, forgot about the second, more recent chart. Just checked my JD9 file and have both there. I have found that the settings for ones setup is just a start and it is beneficial to try different settings to fine tune.
