Using analogue outboard with Digico SD-series

Hello guys,
a few months ago I was asked to do FOH/sound direction for a series of concerts of orchestra + band + vocals. I got to work on a digico sd8 and it worked out very well. Now I'm getting some more of these gigs and maybe I'd try to bring some of my studio outboard to the gig. Using a RME ADI4 I could use my prism sound orpheus for the inserts.
Are there any pro's and (specifically) cons to this? Most notably in the domain of latency?
I mean, the PA will be delayed to make it sound coherent with the stagesound, and external processing will change this, because of the DA/AD roundtrip latency.

I could also use the built in local analog outs/ins of the digico. How do these sound? Will using these have an adverse effect on the audio? I mean, if I'm using a fatso to tame some shrill strings, but the inputs themselves have the effect that I'm trying to eliminate, it might not work out the way I'd hope.

I'm curious of what you think of this. Thanks for reading.

Hi,

I've done this a lot. I use Digico boards regularly.

In terms of latency, there will be a negligible difference between an orpheus and the local inputs. But if you want absolute lowest latency, stick with the internal I/O. The ADI4 and Orpheus will both add a tiny bit.

The internal I/O sounds great. Very neutral, so I wouldn't be afraid to use it at all. Not to mention its an altogether simpler chain. Simple is good for live tours...

I would certainly go down this route. The latency added won't be a problem for a FOH environment.

Just make sure to compensate latency when using parallel-processing..
No automatic delaycompensation on digico!

thanks guys.
I'm somewhat more confident to give it a go now!

entirely correct!

I prefer to get around this by parallel processing with units that do this in one box. like the elysia xpressor
