XLR to RCA But Different Kind of Question

[Trdat]

I emailed Phil and this is his reply.

Here is the pinout of the XLR
Pin1: ground >> RCA ground
Pin2: signal+ >> RCA signal
Pin3: signal- >> RCA not used (leave open).

So am I correct in understanding that pin 3 is left disconnected(floating)?

And this can be on either side of the cable...?

Yes, that's right. As long as XLR Pin 3 doesn't connect to anything electrically, it doesn't matter which end is left floating. It is more usual for it to be left unconnected at the XLR end, as then it's most obvious what's happened. If you disconnect it at the RCA end, then anyone looking at the XLR may think it's connected. Electrically, they're the same.

No.....I don't read it that way.
Pin 3 inside the Marchand unit should not be left disconnected under any circumstances. I'm sure Phil has it connected in some fashion. Either to an active line driver or a simple resistor to ground.

We are taking about the XLR to RCA cable.

That's how input looks at my XM9.

To use it for balanced input you just cut the F trace and connect cold (-) to R25 corresponding input.

"standardization", unfortunately, is relative.

Leave open means disconnected, at least to me.

And we're still talking about the cable here yeh, just to confirm?

Yes.

I needed to go active for XLR to rca from my topping dac. Discussed previously using a matchbox but other options exist
