Remove jumper from minus to chassis at euroblock. Connect shield to black wire at RCA end. This will make chassis currents flow in separate conductor(shield in this case). and not in the signal ground.

Yes I posted in another of your threads about this, that I have knowledge about the internal workings/topology of Xilica's output circuits. I know that Xilica's output circuit is only a balanced impedance, there is no active signal on the minus output only signal ground through an impedance that matches it to the plus output impedance. Therefore we can connect it directly to the ground of the unbalanced equipment at the RCA connector. Thus far I have only used my Xilica with balanced inputs. But have No Fear, it will work.

A lot of Presonus's diagrams are direct copies from Mr Whitlock(see AES seminar linked above). What confusion are you still having about connecting the Xilica outs to the amps RCA inputs?

Exactly the same thing? Well not exactly. They are NOT the same. An ohm meter will tell you they are the same, but they are not. You must think in terms of where the currents will flow.

You must think in terms of where the chassis currents and signal currents will flow. These two arrangements are NOT the same. The diagram does not explicitly show that the black wire is a shield. In the 3 conductor cable the chassis current on pin 1 of the XLR will flow on a separate conductor(the shield) all the way down the cable until it gets to the RCA connector where it will tie to the chassis of the unbalanced equipment. The signal ground current on pin 3 of the XLR will flow through the blue wire of the twisted pair until it gets to the RCA connector where it connects to the same point as the shield, because in unbalanced equipment the signal ground and chassis ground are the same point. In the 2 conductor cable with pins 1 and 3 of the XLR jumpered together the chassis and signal ground currents flow in the same conductor(most likely a shield). This can cause Common Impedance Coupling(CIC). The 2 conductor arrangement is used all the time but is not optimal. Someone may use it satisfactorily for years and then they add a component to their system or just move their system and start having problems because the chassis ground current couples a signal onto the signal ground and the unbalanced equipment has no mechanism to discriminate between wanted and unwanted signals.

Ow. Hurts just to think about it. I hope you are feeling better.

Be nice. We know your wife. And we like her.

If the RCA end is wired properly you're good to go. But I thought you said the RCA to XLR is only 2 conductor. Is it 2 conductor PLUS shield?

Yes. Or order some of these in the length needed. Lop off (or un solder)the XLR end. Use the resulting bare wires into the phoenix connectors: https://www.monoprice.com/product?c_id=115&cp_id=11509&cs_id=1150902&p_id=4777&seq=1&format=2 You will see from their wiring diagram the proper way to wire RCA connector to a balanced cable

Advance to the rear.

https://www.monoprice.com/product?p_id=5279 Get one of these in the wire gauge and length of your choice. The ground prong won't attach to anything anyway. Should still work.

The output of the Xilica is balanced impedance but there is NO SIGNAL on the minus output. It is just ground through an impedance that is equal to the plus output. Does your cable have 2 conductors or 3? The best way to wire this type of output to an unbalanced input (RCA) is using a 3 conductor cable (a twisted pair with a shield). The minus conductor of the twisted pair would then be connected at to the shield AT THE RCA connector along with the shield. This allows the inter chassis current to flow through the shield and not the signal conductor.

I be thinkin' yours is much better than Duff's.

AC and argon insulated windows in a garage? This man spends some serious time in his garage Come to think of it I am contemplating moving the pellet stove I just removed from the corner in the basement where one of my Jubes resides to my garage.

Are you sure you and some of your beer can't make it to Hope next year?(Selfish unabashed request)

Mmmmmm....Beer

I do use berinher 3 way active crossover. Xlr. I think something got lost in translation

Just killed a good sized scorpion in the master bath bathtub. When I get to heaven I will ask the Lord how this happens.

And nails to match I like.

Off to the ocean today, escaping the heat. An old friend who moved to Indiana long ago is out here visiting his family. He has asked me to go sailing in his BIL's sailboat. Wish this old landlubber luck.

Wait......no wait....is this a joke? Don't be rude, never ask a lady her age...… ……."I feel like I owe it to someone"...…. BTW..There are a few other gems on that record IMHO. If'n you've never heard the whole record.

+1 on the 63/37 advice. And the "don't use lead free". Lead free solder joints look like crap even when they're good half the time. I mean it is really hard to get a pretty, shiny lead free solder joint. Get a "soldapullt" for unsoldering the inevitable mistake: https://www.amazon.com/s/?ie=UTF8&keywords=soldapullt+ds017&tag=googhydr-20&index=aps&hvadid=153668187043&hvpos=1t1&hvnetw=g&hvrand=3100941254851300013&hvpone=&hvptwo=&hvqmt=b&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1014327&hvtargid=kwd-2861258690&ref=pd_sl_4brhiyo5sc_b

Cool. Thanks for that. I wish I would have found you guys and this forum a decade earlier.
