If it does invert, and you don't want it to do so, just reverse the (+) and (-) signal connections at the XLR output connectors. If you do it at the speakers you will invert all the other sources.
Does the balanced output of the Sony SCD-1 invert
Does the balanced output of the Sony SCD-1 invert absolute polarity? It's interesting because Sony has no clue, but if you read the Stereophile review, they indicate that it does, and suggest that you switch the postive an negative feeds at the speaker. Does anyone have a definitive answer?
