xlr to rca audio cable

tom418September 17, 2006

I have four cables with RCA plugs on one end, and XLR plugs on the other. On the XLR plugs, pin 2 are "hot".

My equipment (Otari MX5050BII2 tape deck) requires Pin 3 to be "hot" . Why didn't audio manufacturers standardize pin arrangements on XLR connectors? (i.e. with RCA plugs, the tips are always "hot") Thanks.

Thank you for reporting this comment. Undo

A good question. Do those cables have any circuitry in them? Just going RCA to XLR will not produce good audio, as the XLR side is balanced, and the RCA isn't - so you'll get impedence problems. You need a balancing/unbalancing amp, transformers, or a small mixing desk to solve your problem.

You may find more info by searching, but here's an example.
