SPDIF output to AES/EBU input

[Getgaff]

As per title, is this possible?

Some context: I've recently acquired a Auralic Altair which, amongst others, has a AES/EBU input:



I no longer own a digital source with a AES/EBU output and in order to maximise my options, I'd like to use any SPDIF digital source and plug it into the AES/EBU input. I've not been able to find a definitive answer and have tried one of these, but it doesn't appear to work:

EDIT: I am concerned the Neutrik device I purchased from eBay might be faulty, but can't be 100% certain.

Am I on a hiding to nothing?

S/PDIF is 75ohm impedence.
AES3/EBU is 110ohm impedence.
It's not just a simple case of physical adapters.

The Neutrik device appears to offer a 75ohm input and with a 110ohm output. Have I misinterpreted the specs?

I use those Neutrik adaptors at work all the time with no problems. Despite the impedance mismatch, a phono to XLR cable usually works.

Thanks.

That's why I believe the Neutrik device I've purchased is faulty. There's physical evidence suggesting it's been opened. I need to test it before seeking a refund from the seller.

Canare produce something similar, albeit expensive:

I'm uncertain if I can use a (cheaper option) RCA to XLR cable or the more expensive adapter.

I could pop one in the post for you to borrow?

[Getgaff]

Wow! That would be great, thanks. I'll PM you my details.

If you click on 'Drawing' in http://www.neutrik.com/en/accessorie...rs/naditbnc-mx, you will see the Neutrik adapter in question does indeed contain a matching transformer.

By the way Gareth, whereabouts in Chelmsford are you? I live in Great Baddow.

Opposite corner to you, Newlands Spring area. Or Broomfield if I want to sound posh; Melbourne if I don't

I don't think that you can do what you are trying to do as the signal is different for S/PDIF for coax and AES. It isn't as simple as matching impedance like it is with analogue signals.
