Topic: Mixing single and double-wire i/o on HDSPe AES card

Greetings!
I'm about to purchase an HDSPe AES32 card to put in a new 8-core Mac Pro, to serve as a front end for Logic (Mac) and Pyramix (PC via Boot Camp).  I'm a classical recording guy, and have two high-end ADC and DAC boxes, by Crane Song and Genex.  The trouble is that the Crane Song Spider outputs multichannel 192kHz via 4 single-wire XLRs, while my older Genex GX A8 and D8 use 8 XLRs with the double-wide protocol.  It seems to me that, *theoretically,* I could get twelve channels of 192kHz i/o in and out of the HDSPe with my equipment (1-8 using the upper connector, and 9-12 using the eight i/o on the lower connector), but I do not know if this is really possible.  The promo material says that the card will automatically adjust to single/double/quad wire scenarios, but can it automatically adjust to two different protocols at once?  Thank you for your experience!  "Dr. Fred" in Western MA.

Not possible. All ins and all outs have to use the same protocol respectively.

Thanks for replying so quickly.  It's not a deal-breaker; I'll still get the card. ;>)  Trouble is, two Weiss Hydra converters cost more than your card does!  Oh well..  I'll just have to scale back to 8 channels for those situations, or lower the fs if I need the additional channels.
On a second subject--I am assuming that your card will fit in PCIe slot #2, the one adjacent to the "double-sized" slot #1, in which I have only a "normal" graphics card installed.  And that its channel 9-16 daughter card will occupy that unused space between slots 1 and 2, allowing me to still use slot #3 for, say, a small combination FW/eSATA card.  (Slot 4 already has a second graphics card, for monitors 3 and 4.)
Thanks again!

You could use an ADI-192DD to change Double Wire to Single Wire. ADI-4DD does this too, but only up to 96kHz.
