Lynx Aurora summing Audio Interfaces

Lynx Aurora summing

Hi Slutz,

I'm looking into the aurora 16. I see the in's N Out's are done via D-sub connectors. What are most people using to sum the 16 outputs down to a stereo pair. Are a lot of folk just assigning the 2bus from their DAW to two of the 16 outputs and connecting to monitors?

mmm. I am familiar with such a device, only I run a mobile studio and am looking for something a little more portable/

Never used this but it seemed interesting if you have dsubs. Perhaps ask about a 16 channel version?

You could run to a Folcrom and sum in the analog domain [only 1 RU - 16 inputs]

Totally depends.

Some are using mixers.

some are using summing amps.

Some (like us) use the extra IO as hardware inserts and sum ITB.

Some just have them for the inputs and mix totally ITB.

If you connect a pair of outs to your monitors, you'll generally want to put a monitor controller in the way.

The Folcrom looks interesting. I think I'll utilize 2 outputs for a stereo pair and just get some sort of controller. 8 outs for headphone mixes and 6 spare.

Yeah, he'll do a 16 channel version. Great concept, great price. Just put all the resistors in the cable itself. Genius. Lovin' mine.

I run my Aurora 16 into an SSL X-Desk. 16 channels of lovely clean summing, talkback, monitor switching and fx sends/inserts and sounds great.

I love it.

Currently using a Folcrom do to the added channel control.
Prior to that I built a transformer coupled summing panel mounted behind my racks. (thats now currently listed in the GS classifieds)
Unless you have external hardware to interface with, stay ITB.

My question to you guys summing all 16 chs of the Aurora with the Folcrom is what are you using for a 2ch dac for monitoring and how are you piggy backing / breaking out the Dsub for the 2 ch dac with the aurora lynx / lynx AES card? If your Dsubs are all going to the Folcrom.

The only way I can see to do it is to go to a patchbay and only sum 14 chs.

Did you check out the Passive Summing Network that was referenced above? That guy makes the cables to order. I bet he could do you a cable that sums 14 channels and sends the other two to an output cable. I mean, as long as you're getting in and wiring up a D-sub, no brainer.

The basic signal flow i use is this. But I have a dedicated D/A for monitoring.

Lynx Aurora 16 into Neve 8816

I use Lynx Aurora 16 into a Neve 8816 summing mixer and I'm happy with it.
One of these days I may get into designing our own summing mixer but as of now the market for it is much more limited than the one for preamps.

Your dedicated monitoring DAC has analog ins? or..

What card(s) do you have in your computer and what digital signal feeds you dedicated D/A for monitoring.

For example, with the lynx AES card, which has no extra digital outs, as I understand it, you would either take all 16 to a patchbay, or build a specialty Dsub with one AES pigtailed off to feed you monitoring DAC. Which would waste 2 chs of the aurora DA

I have a DA10 and am trying to figure how to incorporate it with a aurora16 and lynx AES, to have all 16 chs for available for summing/mixing.

How have you all managed this? Thanks.

There are multiple solutions to use all 16 channels for summing. But you need to answer a few questions 1st.
  • Do you need a monitor pair that bypasses your summing setup? Or would always monitoring thru your summed output be adequate?
  • What is your summing solution?
  • do you have a monitor controller?

I am using two Auroras (16 and 8) and I am summing the signals on a Speck Electronics console.

The Auroras are connected to the computer via an RME HDSPe MADI card and an LT-MADI extension board mounted in the Aurora 16.

The 8-channel Aurora is connected to the 16-channel Aurora with an AES snake (DSUB-to-DSUB), and I have also connected some channels of Lavry Blue converters (for instance for monitoring) to the Aurora 16 with a second AES snake.

bump!

2 rhythminmind:

hello, would you be so kind to comment on my setup pls!

if i have an aurora 16 for 16 outs going into a neve 8816 at a time and then it comes into Lavry 2 channel AD is this the right option for monitoring? what are the 1/2 ad inputs in your scheme?

I'm also curious... what if I add Api a2d to get 18 channels at a time what is the best way to sum 18 channels into a 16 channel summing mixer?

ty!

I'm in the same situation. Since I run all of my summing through the dangerous unit anyhow, I just hang my monitoring controller off of the monitoring output of the summing amp. Eventually I'd like to get a dedicated stereo D/A, but thats not really in the budget for the moment.

I don't really see an issue with the way I do things now. Might as well adjust for the complete signal path rather than have it be an after thought.

The Dangerous DBox is a great solution for smaller summing setups. It has the 8 channels of summing (on a dsub as well for easy connection), as well as 2 stereo D/A converters that accept SPDIF or AES signal. If you use an Aurora 8, or similar interface, send the 1-8 analog outputs into the DBox for summing, sum out of the Dbox into Aurora ins for printing, then send the summed mix's output back out the AES/EBU IO of the Aurora to a Dsub to XLR AES Digital Snake (Yamaha pinout for the Aurora.) Connect one of the XLR-Males on the AES snake to the "DAW" input of the DBox. Now you can monitor the summed mix pre conversion in the analog world, or post A/D conversion but using the Dangerous D/A which is incredibly clean and transparent!

Aurora 8 and Rosetta 800 here...
Rosetta 800 (8 Analog Outs-Dsub25 Out) and Aurora 8 (8 Analog Outs-Dsub25 Out) > Patchbay > 12/14 channels to Folcrom and 2/4 stay analog to HW inserts.
Folcrom (Out) > GR MP-500nv or HCL Affinity > Patchbay > Aurora 8 (Dsub25 In) > Protools (Printing Mix) > Protools Out - Monitor (Aurora 8 Digital Out) > Mytek 96 DAC (AES In) > M-Patch2 > Genelec 8040 & Auratone (mono).
Next step will be a RND Portico II and a Kush Clariphonic after the PRE and before the way into Protools (printing).

Jared, what if...
I have an Aurora 16 (connected via AES16e card), a folcrom (16 ch), and I add a Dangerous D'Box or Source? How could I get digital signal (the mix post final AD i.e. after an ITB master channel) back to the Dangerous? The AES I/O on the A16 is already completely in use sending the 16 channels out to the Folcrom... Is there a way to get SPDIF/AES to the Dangerous other than buying a 2nd AES16e? (which would be a ridiculous expense for 2 ch)
