Just cut off the XLR and resolder the wires as follows:-
Tip of jack to inner of RCA
Ring of Jack left unconnected.
Sleeve of Jack to ground of RCA.
However, this will only work if the jack is an output, i.e. RCA is an input, based on the XLR being male.
It will also only work if the jack output is electronically (or transformer) balanced centre-tapped. If fully floating (either electronically or transformer) then connect the jack ring to RCA ground.
If the RCA is an output, then connect the ring of jack to ground.

Nope... The JBL speakers can only accept unbalanced connection to their 6.35mm TRS Jack... So I'm trying to connect my dac's RCA to JBL's TRS...So, you're going from the RCA outputs of your DAC to the XLR inputs of your 'speakers.
Therefore cut off the jack, and wire as per above, as follows:
XLR pin 1 to RCA ground
XLR pin 2 to RCA inner
XLR pin 3 to RCA ground.
That should work perfectly.
If you don't have a multimeter to check what terminal of the XLR goes to what colour wire, I suggest you open up the XLR (just unscrew the cable grip and slide the inner out), that will show you what the cable colours are, and which colour goes to what terminal.

Those two drawings are exactly the same electrically. The first one assumes that the cable is balanced, as you have, and the second assumes the cable is unbalanced. Electrically, there's no difference.Nope... The JBL speakers can only accept unbalanced connection to their 6.35mm TRS Jack... So I'm trying to connect my dac's RCA to JBL's TRS...
Should I follow up this diagram? ↓

(TRS tip to RCA tip / TRS ring and sleeve to RCA sleeve?)
Thanks for clarifying... I want to use the JBL's TRS input because JBL 305 manual telling this ↓Those two drawings are exactly the same electrically. The first one assumes that the cable is balanced, as you have, and the second assumes the cable is unbalanced. Electrically, there's no difference.
As to the JBL 'speakers only accepting an unbalanced connection to the TRS jack, that's just wrong, as it has no way of knowing whether the XLR is being fed from a balanced or unbalanced source. However, if you want to use the TRS input, then connect as follows:-
Remove the XLR, and connect:-
TRS sleeve to RCA ground
TRS ring to RCA ground
TRS tip to RCA centre

So then you need this maybe?It would not work... I've two of JBL 305p monitors...
Exactly this. There's nothing that says that the XLR input can't support an unbalanced source. It's just that jacks are available as TRS (balanced mono or unbalanced stereo ) and TS (mono unbalanced) so whichever you plug into the TRS input will work. An XLR used unbalanced as you want to do has to be wired as I've specified above.Thanks for clarifying... I want to use the JBL's TRS input because JBL 305 manual telling this ↓

So I can go with JBL's XLR regardless balanced/ unbalanced?Exactly this. There's nothing that says that the XLR input can't support an unbalanced source.

Yes. The XLR input will accept both balanced and unbalanced connections.So I can go with JBL's XLR regardless balanced/ unbalanced?

connect:-
TRS sleeve to RCA ground
TRS ring to RCA ground
TRS tip to RCA centre
I do the opposite. I ground everything and only start disconnecting signal grounds if I get hum, which is rare. In fact, if I get hum then I use a transformer isolator to prove the point before starting to mess around with lifting screens.Yes. The JBL 305P TRS and XLR inputs supports both unbalanced and balanced connections, as is typically the case.
That said…
I would not do this. I would leave the TRS sleeve (or XLR pin 1), i.e. the shield, disconnected from the RCA ground (i.e. left floating). Otherwise you're very likely to get ground loop issues. See in particular the Rane interconnection note (probably the best reference on this topic), in particular solutions 17 and 18.

If TS shield connects to RCA shield (see RANE 19) then why not TRS shield connects to RCA shield (RANE 18)?
