Neutrik NA2M-D2B-Tx balancing transformer adapter review

[JediJoker]

So... Am I an idiot for using these as RCA-to-XLRM at my receiver and XLRF-to-RCA at my subwoofers? The signal cables have long runs (15 ft.) in parallel with power (120VAC @ 60Hz) and trigger (12VDC) cables. My thought was that I could avoid mains contamination of the line level signals via CMNR, rather than relying on shielding alone over an unbalanced cable. I have enabled 1 PEQ filter on my subs to compensate for the rolloff starting at 40Hz (+3dB @ 20Hz, Q = 2, bell as shelf is not available on SVS SB-3000).

RCA to XLR-M is harmless. Could even have benefit if you link ground at RCA side.

XLR-F to RCA requires some analysis to be done right, without adding distortion.

Is there a better off-the-shelf solution for the balanced-to-unbalanced conversion that still retains CMNR?
