Hello to everyone, I have a little problem. I have a DAC with integrated preamp with two XLR outputs, also I have a two active speakers with XLR inputs and one subwoofer with one xlr input and I want to connect everything together. Problem is with sub, because it has only one XLR imput. How could I do that? I have read internet but couldn't find answer, found little info that I need two channel line level mixer (combiner) with two XLR inputs and one XLR output, but don't know which one, which one will suit my needs.... so please help me with this 🙂

Sorry, but I think this is not an option, I want a stereo sound not some semi stereo or pseudo stereo.
The point is you only have one subwoofer, so it would not make that much of a difference. But if you must have "stereo" in the subwoofer, then get a Y cable to sum the two channels into mono.
Well, I don't know I could to that because my two XLR monitors will be connected from the same preamp XLR outputs and then they both will be playing mono as sub, am I right?
No, they don't have. My monitors are JBL LSR28P and sub is Paradigm Sub 15 and DAC/preamp is Teac UD-503.
So you need 3 Y splitters - 2 Y's to split the L/R outputs to the monitors and the remaining Y, and 1 Y to combine the L/R for the subwoofer. Just make sure you get the sexes of the XLR connectors right.
I think these should work:
2 x
1 x

I thought about this, but if I do that in my opinion if I merge L and R channel together for sub, then it also will be merged for speakers too and they all will be playing same mono signal?
I think you are right, you need to add some resistors in the "sum" Y adaptor to keep the L/R signal isolated.

Yes, I read about this option, but with this solution also is something wrong don't remember what, I cam to conclusion that I need line level signal merge device, but don't know what brand and model.
The passive summing adaptor is the cheapest solution, if you want to spend more money, you can of course get an active summing adaptor or a small mixer. I would try the passive adaptor first, the result might be acceptable to you.
Maybe You could be more specific about the brands and models of the passive summing adaptors? It is possible to use some kind of microphone 2 into 1 combiner, I saw them on the net? It will be used to sub, so frequency response shouldn't be higher than 10hz, 20hz is not an option.

If you are handy with a soldering iron, you can buy the adaptor and add the resistors yourself. If not, we have to look around for one already made...
Thanks, but I have one more question, in this combiner spec is written 20hz to 20 khz, but mine sub goes lower than 20hz if there will not be a priblem with frquency loss?
