Aurora 16 + Pro Tools HD native set up question

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have six Aurora 16's currently in use on 2 Mac Pro's (also a couple of 8's running on mobile rigs)
Each Mac Pro system is connected with a single LT-FW card and 2 LT-USB cards
I need the LT-FW card as along with it's 16 analog I/O's I also connect a Cranesong HEDD/BURL B2/Lavry Gold AD/DA and a a couple of Bricasti M7's via AES

Everything works fine and is 100% stable (I'm using an aggregate device to run in Cubase and PT)
I clock all the convertors via WC using a Apogee Big Ben

I've decided to change one of the Mac's over to a PT HD Native system and wanted to check what I need to do that correctly

I only want to use 3 of the Aurora 16's and am hoping to get the most I/O's possible

The PT Native PCIe card has the Primary and Secondary ports 
If I get 3 x LT-HD cards what is the best way to link the Aurora's to it and what track count options will I have?

I only really need 8 AES channels as I can use the Bricasti's as analog on my console rather than having them as hardware inserts in Cubase/PT

The reason I'm a bit confused is that the Sound on Sound review suggests I get 32 channels (16 analog & 16 digital) per card
'...use an Aurora 16 with the same card, and you'll have access to 16 great-sounding analogue and 16 digital channels — so 32 channels of I/O in total — in a single 1U box...'

But the LYNX website says 
'...16-channel mode provides one instance of the 16 x 16 analog in and out model...'

Also will I still be able to use the 3 connected Aurora's in cubase via an aggregate device or is this not possible when connected via LT-HD cards

Thanks very much for any help you can offer

	Well, you are right the Auroras can be run in 32 channel mode (16 analog + 16 digital) or in 16 channel mode (all analog). In your case, you could run the three Auroras like this: Port 1 of HD Native connected to the Aurora16 in 32 channel mode Port 2 of the HD Native connected to the other two Aurora 16s, both in 16 channel mode. You can daisy chain these by going out of the expansion port of the first into the primary port of the 2nd. I believe that an HD Native only presents 32 channels to a regular Core Audio app like Cubase, but I'm not positive about this. Avid would have details I'm sure.

	Thanks Paul I'll try and find out about HD Native only showing 32 channels to Core audio apps I'm keeping the LT-W & LT-USB's anyway so worse case scenario I can put them back in for a cubase session

	I just checked the Sound on Sound review again and it clearly states that you get the full 64 I/O when using as a core audio device Not sure how I missed that before but thought I'd post it in this thread in case anyone else wanted to know
