I can see that ground wire is soldered to pin 1 of both xlr connectors.I have turntable with a tonearm that has a 5pin din output. I own an Eleac Alchemy PPA2 phono preamp that has a balanced input.
Unfortunately, there is no sound coming through the Right channel. I asked for support at Eleac. They told me to bridge pin 1 (ground wire) and pin 3 (negative) of both the XLR3 connectors. I have no issues when I connect the turntable unbalanced to the phono preamp.
