RHA L1 DAC AMP mini XLR pinout

Recently I had a chance to work on an adapter to convert 4 pin mini XLR to 4.4mm balanced connector. After the adapter is completed, I noticed that the audio out from RHA L1 with the adapter sounded mono so I bring this question to RHA support team.

It seems that RHA had swapped the negative pin for right and left on their L1 DAC AMP. Here's the correct pinout, huge shoutout to RHA support team who's kind enough to provide the pinout configuration in the form of image.


Pinout:
Pin 1: L+
Pin 2: R-
Pin 3: R+
Pin 4: L-
