96 I/O with Aurora 16

[pie55]

Hello,
I'm going to buy a 96 I/O and use it in my hd2 system.
I currently have a Aurora 16 converter.
My question is do I plug the 96 into the expansion port of the Aurora or do I connect it to the HD process card?
Thanks

Either or will work. I think if you plug your 96i/o into the process card you can run the Aurora in 32 channel mode (16 analog, 16 aes) That is the only advantage. Disadvantage is that you then need a longer digilink cable to get to the 96 i/o as opposed to the 30cm one that you can piggy back them together.

Ghengis is correct. I'd suggest plugging each interface straight to its own card, and utilize your Aurora in 32 channel routing mode.

Using the Aurora in advanced routing mode will keep Pro Tools' delay compensation on channels 9-16 correct.

I'm a little confused. I'm using an Aurora 16. Do you mean channels 17-24 to do with the delay compensation?

Sorry for any confusion. I'm just suggesting that each interface be connected to it's own HD card. Doing it this way, the Aurora can be used in 32 channel mode (and it will show up in Pro Tools as two Digi 192 interfaces and will be sample accurate to the 192s converter latency).

If you were to connect the 96 i/o and the Aurora to one HD card, and use the Aurora in 16 channel mode, there is something you should realize about i/o 9-16 on the Aurora. Pro Tools will not be able to properly compensate for the latency on 9-16.

Below copied from page 9 of the Lynx LT-HD Manual:
"Since ProTools will only display 16 analog inputs and

8 analog outputs (this is a limitation of the 192 I/O that the Aurora mimics), the Aurora has been
programmed so that Analog Outputs 9-16 are mirrored by Digital Outputs 1-8 when in 16-

channel mode."
