He means the signal level, not that a literal microphone is connected.I feel like I’m in a loop. What microphone connector you know of that use RCA connector?
But the device PMA reviewed had male XLR, this one is female. The general Idea, I think, in this configuration at least in most case, to keep the signal balanced to do the distance, and use a short RCA if you absolutely need the said signal to be connected to an unbalanced input. Not saying that it wouldn't work the other way around with the proper M-M turnaround coupler (Neutrik obviously sell those in it's an other practical tool), but why would you? All Live venues and Broadcasting facilities have a couple dozens high quality DI boxes that performs miles better than this and are made to do exactly as you said. They are essentials, not "Problems solvers" You will need to use them if you want to use unbalanced sources, located more than 15 feet or so away.These devices seem to be designed to be used with the RCA on the source side and the XLR on the load side (see PMA measurements).
The goal is to 'solve problems' and those usually occur with RCA out (ground loops).
This device breaks ground loops and balances the signal so should be used near an RCA source and as long as the signal isn't too hot works good enough for that usage.
Just not suited for hifi sound reproduction with 2V output levels.
In the early days RCA out was closer to 400mV b.t.w. which would be a bit too hot but can be padded if need be.
Balanced works fine for small mic signals over long distances as well.
What other audio signal are there that is at microphone level that use an RCA connector, other than a turntable cartridge, which is surely outside the use case of this adapter?He means the signal level, not that a literal microphone is connected.
We (at least I) need clarifications:
Amirm tested on this thread NA2F-D0B-TX (female XLR & RCA).
PMA tested on his thread NA2M-D0B-TX (male XLR & RCA).
My naive understanding is that;
NA2F-D0B-TX (amirm tested) is designed for balanced-XLR into unbalanced-RCA conversion,
and
NA2M-D0B-TX (PMA tested) is designed for unbalanced-RCA into balanced-XLR conversion.
If my understanding is correct, the two threads are quite different stories with each other, as I pointed and shared here and here on this amirm's thread.
Yes.I may try to measure my NA2M in reverse direction to make it same as NA2F. However, I do not expect almost any changes, because L1 is same as L2, as I have measured in the second thread.
The biggest and main difference is that I measured the adapter from preamp with 0.056 ohm output impedance, though Amir used AP with 40 ohm output impedance. This is a crucial difference with respect to laws of electrical circuits and principle of audio transformer function.

Yes. Regarding NA2M, I think the purpose and use is clear. Regarding NA2F I find the purpose confusing, because the manufacturer shows exactly same circuit schematics for both versions:

But I wonder what kind of line level source could have this low an output impedance in real life.
This is the example of adapter use – the system with Topping DAC, Headamp2 and Cosmos ADC has ground loop issue (if USB isolator is not used) that results in this horrible buzz spectrum:
Good suggestion. Will include in future tests. I think owner has bought two more devices to send in.but Multitone tells you immediately almost all you want to know:
Vraiment, certainement."pas de quoi en faire un fromage"
This device should not be used with home audio equipment but only because it is not suited for home audio signal levels.Dont use,
By using a transformer (passive, requires no power, galvanic separation, signal fidelity is lowered)XLR is a balanced input, how can an unbalanced RCA input convert to balanced input?
