Help with denon DL103 with preamp

IMG_8621.jpg
I just ordered a FX AUDIO Box 02 Phono Preamp for my denon dL-103 MC cart.
The FX has a few dip switches that I’ll need to setup for this denon.
What settings should I use ? Here’s a photo showing the dip switches.
The 3rd photo shows my cart, yes it’s a white line on the front. And from what I can tell it’s the DL-103 original MC .
I know that I did not buy the best phono pre, but that’s all I want to spend on this for now.
Thanks for any and all help with thisIMG_8622.jpg

I load my DL103 at 110 Ohms. I've seen others load it as high as 1000 Ohms. You can try all the combinations and see, though, it seems a strange set of options of 51, 910 and 1000 Ohms.

So set the 3 dips at left at 1 off, 2 and 3 on for low output MC.
Try the others at 1 off, 2 and 3 on for about 475 Ohms.
The switches 4,5 and 6 shouldn't make any difference, they are for MM loading.

You can play around with all of them to hear what you get. 51 Ohms might sound better to you, or 910 may.

Do have the volume muted or the pre off when you make changes to avoid speaker damaging pops.
