Cartridge Loading for a phono pre amp

Hello,

I have recently acquired a phono pre amp recommended by Michael Fremer.  It is “THE VINYL”, from QHW audio, Spain.  It got a great review.  I have a Benz Micro Glider rated at 1.1MV.  I have no idea how to set the dip switches for MC Load impedance for this cartridge. The options I have are as follows: 47K, 1K, 560R, 470R, 100R, and 47R.  I have a solid state amp and pre-amp, and also have a sub that I use, rarely.

Any advice would be most appreciated!!

In general, you set the load impedance to 10x the internal impedance of the cartridge. So for example, if 30 ohms, 300 ohm loading is a good place to start.

I think your Glider is the SM ( medium output level) with 24 ohms resistance and recommended loading is 240 ohms or higher.

If 100 ohms loading is too low and 470 ohms is too high, you can turn on both 470 ohms and 560 ohms to get approximately 250 ohms loading.

Think this may be right:
 

If 100 ohms loading is too low and 470 ohms is too high, you can turn on both 470 ohms and 560 ohms to get approximately 250 ohms loading.

Certainly will be the closest.
