Dual BNC (confirmed to AES3 standard) Digital Out PCI Card

[peterlim8]

Is there such a product? If yes, please recommend. TIA

 

To install onto a desktop and output 384 from each BNC out.

You can find various interfaces with multiple AES/EBU (XLR) outputs, but coaxial in such is not so usual and BNC even less so.

 

Your request sounds like mixing professional AES interface (over 110 ohm differential) and consumer S/PDIF (over 75 ohm coaxial).

Lynx AES16e + CBL-AES1604 , RME HDSPe AES, or Marian Seraph D4

 

and use AES3 to AES3id impedance conversion transformers : Canare BCJ-XJ-TRC or Neutrik NADITBNC-F

 

note: AES3id is not conpatible to S/PDIF coax

 

[yamamoto2002]

It seems canare BCJ-XJ-A10TRC is better than BCJ-XJ-TRC for this application.

While AES3 over coax is not the same as S/PDIF, it's covered in:

AES03-4-2009  (reaffirmed 2019) Annex D (normative) Coaxial transmission

[Miska]

Usually transmitters and receivers are compatible with both AES and S/PDIF, just some status bits are different.

 

But AES over coaxial is unusual, and dual-wire AES over coaxial is especially unusual, so not many interfaces have it built-in, especially with BNC connectors. If they have, they usually have RCA connectors and you can then select either S/PDIF or AES data.

Lots of info onAES3 from the old Rane library:

OT description is vague but I thought about there may be a dual AES3id BNC input DAC  that is similar to dual AES/EBU (XLR) DoP DSD128 input which dCS Vivaldi or Aqua Acoustic Linq has, exists somewhere in the world ?

 

If DAC input is dual AES XLR, no conversion is necessary because typical multi AES/EBU output PCIe cards output AES3 XLR.

[Miska]

I think some Chord DACs have dual-BNC S/PDIF input.... But that's pretty much only thing I can think of.

 

dCS, AFAIK, uses standard dual AES XLR.
