Help linking two Profire 2626's for 16 outs

Hey everybody, I have recently done huge upgrades to my studio and I am looking to have 16 ins/outs at once. I have two Profire 2626's that I connected to my Mac. The issue is, the extra 8 outputs are not recognized by either Pro Tools or Adobe Audition.

I am able to record through the added 8 inputs, but the added 8 outputs just don't show up anywhere. This is killing me as the reason I got these was to link them for 16 outs to my mixing board. Any ideas/solutions/experiences with this?


Thanks!!!

You have to use first Profire unit as a primary interface, which will be connected via Firewire to your Mac.
Second (expansion) unit will operate in standalone mode (without Firewire connection) and will be connected to the primary via ADAT I/Os.

To do that, you'll to setup the expansion unit first. This is one time operation. Disconnect primary unit from the computer and connect just this expansion one.
Open ProFire Control panel and look to settings tab, there is a section for standalone mode settings. There you can set its operating mode to A/D – D/A, set its sync source to ADAT (so it will then take synchronization from first unit) and finally set mode for optical port B to ADAT.
If you then power-off and disconnect this expansion unit from computer, those settings will be remembered and the unit will be working as a standalone converter/preamp with ADAT I/O.

Then connect optical cables between primary and secondary unit.. two will be enough for working in rates <48k and four will be necessary to use for full channel count using S/MUX at higher rates (each cable will carry 4 channels at 88.2/96k.. you'll need 8 in and 8 out, that's why you'll need 4 cables).

Finally connect the primary unit to the computer via Firewire and navigate to the same settings tab at Control panel. There are hosted mode options at the top of UI.. there you have to select ADAT mode for optical port B. And sync source as internal (expansion unit will be following that via ADAT connections).

That's it.. analog inputs from expansion unit should be accessible as an ADAT channels and you should see them on Control panel screen with meters.
To access its analog outputs from DAW, you'll need to navigate to routing tab there, where you'd select appropriate SW return channels as a sources for ADAT outputs.

There is also option to aggregate two Firewire interfaces at OS X level, but this ADAT standalone solution is better and more reliable IMO/IME. If you set that right, all audio streaming will be handled by the single primary unit, you can use one common monitoring mix and there won't be any syncing issues.

Pretty sure you can't run Optical B as ADAT in standalone mode, except under SMUX conditions.

Like...99%.

S/MUX is exactly why I mentioned it and explained, why is it useful for running of higher sample rates..
If both optical ports will be used just for interconnection of two ProFires, then it would make sense to me to connect all ports and set them to ADAT mode.

Wow, this was great! I got all sixteen outputs working now.

Thank you all for the help!!

I agree completely, and with the OP functional and happy, I hesitate to even get into this, but...

"In Standalone Mode, Optical Port B can only be set to ADAT when the interface is operating at SR 88.2 to 196."

(From the manual)

What makes sense to both you and I, simply isn't allowed at 44.1 or 48. At those SRs, in SA Mode, you don't get 2 ADAT ports, you only get 1 ADAT, and 1 optical SPDIF.

I don't think this would stop you very long...me either, but...it could have been a prob for the OP, so I mentioned it. He's past it, so it's moot now.
