George, I don’t know about the adapters you suggested, but IME most XLR to RCA adapters short the signal on XLR pin 3 to ground (XLR pin 1). That will be appropriate for many XLR outputs that are transformer coupled or "cross coupled" (as well as being appropriate when adapting RCA outputs to XLR inputs), but will definitely cause problems for **some** actively driven differential outputs. See this thread
, for example. And also note the following statement in the second Rane reference I provided earlier, pertaining to actively driven differential output stages:
Mark off even more points for potential distortion (depends on op-amps,
and exact configuration), oscillation, and failure, resulting from
asking one side to drive a short (the result of grounding one side for
AJCrocker1, yes, use of an adapter cable will not be a suitable approach if the balanced outputs are referenced to a DC voltage. However, I have never encountered either a consumer oriented or a pro oriented XLR output that had XLR pin 1 referenced to a DC voltage, rather than to ground. And presumably likewise for the "S" of a "TRS" connector. If you are aware of an exception to that I would be interested in knowing about it.
