Dipswitches for Lehmann Audio Black Cube SE II

I purchased the LA Black Cube as a phono preamp for my Rega Planar 6. I am using the Ania Pro cartridge. Can someone (who knows more than I do) confirm if my settings/switches are correctly set?

Here is the manual:

Here is a snipit of parts of the manual:

 

 

I currently have the switches set for:

  1. MC / 100Ohms (mid output) (called Switch A in the manual) -- what’s the other 100Ohms if this one is "mid"?
  2. +10db Gain switch (called the first switch of Switch B in the manual)
  3. Lowest Bass Roll-Off since I’m using a SUB (called Switch C combined with the remaining two switches of Switch B)

The recommended Ania Pro settings per Rega are:

looks like you have it right- 

windows 1 and 2-   1 on (MC) and 4 on (100 ohms) 

windows 3 and 4-   1 on (+10 db, 66 db total gain) and 2 on (this is the 23Hz roll off filter.  I used this setting with my subwoofers and bass sounded tighter and snappier.  Also the bass roll-off is before the gain stage which helps lessen the load on the phono preamp by not having to amplify rumble and LP subsonics.  

windows 5 and 6.  off off.  these are additional bass filters after the gain stage and not required if you use switch 2 in windows 3 and 4.
