You can use XLR to the Sub. Be sure to check the Sub's own volume level is set correctly. Use a calibration track and an SPL meter.Hello,
question, is it possible to use rca and xlr connections mixed with the d2v3d? I currently have all my power amsp and subs connected with RCA. But i have bought a pro cinema subwoofer with an external power amp that only has xlr and trs inputs. So question is, should i use rca to xlr, rca to trs connectors or i can use XLR connection straight into the power amp? What would be the most beneficial ?
