I was about to say "yes, delay on mains and the Aux outputs. That's what the spec says.
Then I thought, I'll power the thing up and check.
And I couldn't find the setting! Took me a few mins to get there ...
I had sort of assumed that it would be on the "Processing > Output" pages - that' where you find the Parametric/Graphic, the auto-feedback processor, the EQ and limiter for each output channel. But the delay is on the "Config>Output" page - which is also where to set whether the output is pre or post fade etc.
The one awkward thing about using the aux outputs for delays is that if you want it to be a delayed replica of FOH, you'd need to set the aux channels to be post-fade, then set all the aux faders at 0dB. However, the main L/R fader will not impact that aux; you may want a single fader controlling your main levels and the delays.
The unit at present does not have DCA groups, which would give you this functionality - it's one of the most requested features on the A&H forum. The other one that's regularly requested is mute groups. Both rumoured to be "in the pipeline for a future firmware release" - at present both can be implemented via MixingStation, but not with the A&H native tools.
First impressions of the unit are very positive, but not used it in a real world gig yet.
