A little while ago I bought a UMC-1, and hooked up my subwoofer using a single RCA cable. Not the Red+White RCA- just the red one. The UMC-1 only has a single RCA or a 3 pin XLR for the subwoofer output.
I don't know if it makes any difference, but I power my sub via a NU3000DSP. It has combo 1/4" TRS/XLR jacks. Originally, I was hooking the UMC-1 up to the NU3000DSP via RCA > 1/8" TRS adapter > 1/4" TRS adapter.
Yesterday, I replaced the RCA with a XLR cable, and immediately noticed that the subwoofer seemed to have better transient response. The subwoofer didn't seem to be any louder, but it did seem to be snappier, etc.
Does XLR provide a higher voltage, therefore making my subwoofer play louder (even though I didn't perceive it at being louder)? Or does XLR simply cancel out some noise, and the problem may have been that my previous unbalanced subwoofer hookup was slightly noisy (even though I never noticed any noise)?
Perhaps going from RCA to 1/8" to 1/4" was lowering the input voltage on the NU3000DSP?
I'm wondering if my feelings that the sub sounds better would go away in a DBT?
