Sutherland PhD Phono Preamp owners - Settings for.


Fine People,

I have a Sutherland PhD Phono Preamp, what settings on the phono preamp are required in order to accomodate for a Ortofon 2M Black cartridge. (MM)
I can confirm the cartridge loading is 47k

Specifications Ortofon 2M Black:

•Output voltage at 1000 Hz, 5cm/sec. 5 mV
•Channel balance at 1 kHz 1 dB
•Channel separation at 1 kHz 26 dB
•Channel separation at 15 kHz 15 dB
•Frequency range at - 3dB 20-31.000 Hz
•Frequency response 20-20.000 + 2 / - 0 dB
•Tracking ability at 315Hz at recommended tracking force 80 µm
•Compliance, dynamic, lateral 22 µm/mN
•Stylus type Nude Shibata
•Stylus tip radius r/R 6/50 µm
•Tracking force range 1,4-1,7g (14-17 mN)
•Tracking force, recommended 1,5 g (15 mN)
•Tracking angle 20°
•Internal impedance, DC resistance 1,2 kOhm
•Internal inductance 630 mH
•Recommended load resistance 47 kOhm
•Recommended load capacitance 150-300 pF
•Cartridge colour, body/stylus Black/Black
•Cartridge weight 7,2 g
•Replacement stylus unit 2M Black.

PhD:

Gain Settings: 45 dB / 50 dB/ 55 dB/ 60 dB / 68 db / 74db
(what setting is recommended here) ???????

Please and thank you

Thanks, 45db is the only gain that works.
All others give a serious distortion in the signal.

Appreciate the input
It will also depend on the preamp's/linestage's gain, but I
would think the 45db should be more than enough. Most
volume controls should be set between the 10 o'clock and 2
o'clock range for proper tracking and sound. If the 45db
gain doesn't accomplish this, try the 50 db setting.

The Ortofon Black has a 5mv output which is pretty high.
