You should not have any problems at all straight away as I understand. The default possibles of the internal pins should work for you. You could ask this question on the Lavry forum or search over there for an answer if you want.

Question: "According to the user manual of DA10, it seems there are jumpers needed to be adjusted inside the case of DA10, do i really need to do that when i am using an XLR-RCA adapter or balanced to unbalanced cable?"
Answer from Lavry tech support:
"The DA 10 has amplifiers driving both signal pins of the XLR connector for balanced operation. They are short circuit protected, but operating the DA 10 with one of the two signal pins shorted to ground will raise the distortion in the active output. Most off-the-shelf adapters DO short one of the two signal pins to pin 1; in most cases Pin 3 is connected to Pin 1 inside the adapter or adapter cable.
The DA 10 comes from the factory configured for balanced operation.
So in most cases you SHOULD set the internal jumpers of the DA 10 for unbalanced operation.
The only exception would be if you have a more "custom" wiring scheme for unbalanced operation, or want to have the flexibility to change from feeding balanced inputs to unbalanced inputs with dedicated cables for each case.
For example, an unbalanced cable would be wired so there is nothing connected to Pin 2 of the female XLR that plugs into the DA 10. The signal return or "LOW" side would be connected to Pin 1 along with the shield (in the case of twisted cable) or just the shield connected to only Pin 1 (in the case of coaxial cable). The signal conductor or "HI" would be connected to Pin 3 in the XLR and the center pin of the RCA connector or tip of a mono 1/4" plug.

Bummer... this is the kind of thing that would send someone that is not too technically inclined (like me) off the fence to the DAC1.
With the lack of RCA outputs you'd think the design of the XLR's would have been a bit more versatile and user friendly.

I know how you feel but the default setup in those plugs are supposed to be correct for what you need as is.
Here is what I understand. Normally the signal pin is number 3 on the Lavry. It is my understanding that the default for plugs is signal on pin 3. If this is not the case for the plug then you will have to open the Lavry up and reset the signal pin to 2.
After this the issue is do you want to operate balance signal or unbalanced. If you want to operate unbalance you will need to open up the Lavry and reset the jumpers to unbalanced.
The main difference in operating with the RCA plugs as default for both the RCA plug and the Lavry is that under balanced operation you will have 6 dB higher signal level which has a potential to over drive your amp. If you go default you will want to keep the volume level on the Lavry below 34-40. If you open it up then you will still need to keep the volume level no higher than 46 for the same reasons. I have my Lavry set on 36 using default setup. I have yet to open it up.
Since talking about it I thought that it would be best if I actually opened up my unit and did this. So I did after checking out this thread over on the Lavry Forum. Here is the image that spoke to me. I simply changed the jumper of both channels for the 3 pin from hot to ground.
I was reading the forums regarding the "crystallock controversy"......
and noticed that you posted on that topic a few times.
Am I to understand that, as per the Lavry CEO's post on the Lavry forum, the DA10 does in fact use SRC to deal with jitter ??
And that the manual and website have now been corrected to reflect this info??

Thanks.
Let me say that I don't know the ultimate answer about this issue but I do know how it sounds, very transparent.
If anyone wants to know what Dan Lavry has said about this go to his forum. All my comments concerning this related mostly to a designers preference and good sense to keep designs proprietary, which is the only way to keep people from stealing you ideals.
