RCA to XLR Cable ("pseudo-balanced") to buy ?

[kongwee]

I would say you may face problems. Most of what I read in that Hypex stuff looked like baloney to me. In most use cases wiring pins 2 and 3 to the RCA plug will work fine. If you have ground loop hum the 100% solution is a quality isolation transformer. Standard mic cables have pin one connected st both ends because A: It is the safety ground for a dynamic microphone and B: It is the return for the phantom power for a condenser mic.

If they think those wiring schemes give all the advantages of a balanced input with an unbalanced source then they don’t know how balanced interconnects work.

Not just Hypex but a lot of manufacturer suggest such stuffs too. That why you can get pre make and DIY on these stuff. Under you see similar thread tabs, you see such problem is very common in ASR. Also you will get 6dB losses, by graph it isn't an issue so Hypex has such a low SINAD. If you get used to hear Hypex in balanced mode, you will notice a less detail presentation with such adapter. Plus possible to induce noise not just ground loop.

If it is not primary source of listening, you can just bet on it.

My experience with this model is that the RCA jacks are very tight and the cable is pretty stiff.

The thing that convinced me to use the recommended cable was reading on a pro audio site that the proper cable results in up to a 30db lower noise floor.

The fellow at Buckeye who sales Hypex, and Purifi suggest the Monoprice RCA to XLR cables.

I've used this with various amps, but I haven't used them with Hypex.
They do not have the capacitor and resistor on Pin 1 shown in the Hypex datasheet. They do mention that with most gear it can be shorted. I don't know if anyone makes a ready made cable with that.

Worlds Best cable makes one with better components. Cost is twice as much.

I have both brands in XLR though only the Monoprice in RCA to XLR. Never had trouble with either one. The WBC is more supple and thinner with the Monoprice being thick and a bit stiff.

Redco Audio does fine work.

The design begins with a rugged flanged enclosure that comes standard with gold plated XLR inputs and RCAs plus a removable screw-down barrier strip for easy installation in NEMA enclosures and 19” racks. Plug and play easy to use, this passive interface does not require any power to work...

this is the bees knees. at least one of them.

Could one recommend such cable offering in Europe? All listings mentioned have extremely high shipping costs, thank you.

I use cordial cables only - high quality, low price. e.g.: https://www.thomann.de/de/cordial_cfu_3_mc.htm

Thank you, just to reafirm is this Cordial cable is up to hypex recommendation?

Don't know, but I use it with my Purifi without issues.

If you convert balance or single end in non active way, you will face problem. These are already threads popping out regard to the same issue..

Unbalanced outputs usually drive balanced inputs just fine. It's balanced outputs to unbalanced inputs that's more problematic.

Probably I didn´t got it:

Shield of RCA to Pin 3 (black) and Pin 1 (grey) of XLR is shown in the Cordial Picture, as well the Hypex Picture. What´s the difference?

I have a pair of WBC (World's Best Cables) I got on Amazon. Happy with them and no hum or apparent wiring issues. Dumb name I know, but they're reasonably priced and seem well-made.

WBC RCA to XLR cable are well made, and cables are flexible enough to manage easily.
Monoprice cables are quite thick, work just fine, but a bit ridgid.
