Hi
i connect my kemper to my QU-16 via the main outs (for my IEMs space feature on here aswell) and then for the front of house I go monitor out. This way I can EQ the front of house sound and separately EQ my IEM sound. You could try this way. I'm very happy with how this works for me
Yes a good solution but with the disadvantage that your foh signal is only mono. And for a better finetuning a eq like the studio eq would be better.
You could use a stereo splitter from the headphone jack to your mixer and reserve the main outputs for the FOH. This would enable you to have space only on headphones and the normal signal for FOH. You could also EQ on the mixer.
You could use monitor out and direct out if you want stereo though FOH. The QU-16 has a very good EQ for fine tuning, I've not used the X32 but I would have thought the EQ on there would have been capable for fine tuning, is that not true?
I could use monitor out and direct/main out but they use the same output eq. If I would for example reduce some highs in the monitormix this would influence the main mix and vice versa.
If I get the complete in ear-signal including my guitar from the mixer it is possible to finetune the monitor with the eq of the mixer but then the latency is higher.
I dont get any latency from the desk when i use the QU-16 and feed to my IEM, the x32 must introduce this?
Each digital mixer like each digital unit has a slight latency and they are aditive. So if for example the kemper has 3ms and the digital mixer has also 3ms you will get 6 ms and this can you feel.
In my world I ran the guitar signal straight from the kemper to the inear transmitter and the monitor signal that comes from the mixer will be added ("aux in to headphone")
I would be be interested to see the spec sheets on the latency for both the x32 and QU-16, because I feel no latency at all with my set up
Yeah I would because I think the KPA latency is lower than 3ms around 2.5 I think I can't remember off hand. So all together around 3.7ms and I can't detect that when I playing 
You are right, normally such a low latency is not detectable. We will see ...
Could you please describe how you use your inear monitoring. Do you have different eq settings in the mixer ?
Yep the monitor out is EQ'd for our yamaha PA so EQ'd from the desk and then the stereo mains is EQ'd for my IEM's again EQ'd from the desk
Ok I´ve checked it and the latency feel from the x32 is different if you use the headphone out or the aux out !
So I use the aux out and everything is fine.
Thank you Raoul23 for your help
Excellent!!! Glad I could help, Now get rocking
So if for example the kemper has 3ms and the digital mixer has also 3ms you will get 6 ms and this can you feel.
6ms is borderline of what anybody is able to sense. Sound travels at about 1ms/ft (3ms/m) so 6ms is like standing 2m further away from an amp/speaker than you normally do.
I'm running my IEMs from the monitor-outs on a X32 at smaller events where I mix from the stage and have to balance the FOH mix myself. With a sound-man involved I run the IEMs from a separate pair of outputs on the X32 that I can EQ and mix myself. Latency is no issue with any of these alternatives. The main pitfall with latency is if you mix two signals with different latency. Only a couple ms difference may give quite nasty phase-shift issues, particularly with a signal that involve stereo effects.
I guess the matter is more complex than this.
I don't trust the "x ms = Y m" equation. There's a brain in between
If the source is placed 10 m far from me and I perceive a delay in the sound, I am able to integrate all the info I'm receiving and to get a coherent feeling. If a cab is 1 m far from me with the same acoustic delay, the info the environment is sending me are not coherent with the delay I perceive, and I find the latency more critical.

You mean the brain adds to the latency? Well...
I agree that perception may be different, moreso initially but I also want to say that these few msecs could then easily be compensated by the brain with a 'getting used to parameter' (i.e. it would take a little while).
My brain latency is awful. Especially in the mornings
