I've done some shows, pop concert, orchestra, symphony, where almost all the subs were nothing more than something to set the top boxes on, On the unused subs I plug in shorting plugs, does that help anything.....at least I feel better that I did it!!

Does a backline bass rig cancel frequencies in the PA?

Nothing really wrong with what you had, the UI24 will do a high pass on the outputs.
You looking for a mixer surface or a rack mount style.
I've done FOH and/or played at a dozen or so places the last few years, and all of them have PA's that are hung. The only place I see PA's ground stacked any more are temporary festival setups. Different worlds…
I have some flyable boxes but not a full big or even a medium flown line array system, for the shows and market I do the ROI would not be there, for that kind of system, if needed I'll rent. Sometimes the best ROI gigs are out of my mini van!!! It all depends.
No, the issue is that people are saying they can hardly hear my bass through FOH so my bass amp on stage isn't competing with the P.A. At the moment my onstage amp is quite low as I was trusting that it was being pushed out through the P.A. but this isn't happening.
I am thinking of raising my bass amp volume on stage to compensate for the sound guy hardly having any of the bass going through FOH.
I understand what you're saying, but you have a FOH person that, assuming you're getting good info, doesn't like bass. And you're gonna give him a bunch of bass that he or she doesn't want, and he or she won't be able to do a thing about it. FOH is a very tough job, and when the band works against what you're trying to achieve….I predict you will have conflict. This probably won't end well.
Is this a place you want to play again in the future? If so, cooperation and negotiation is the route to take. Your tactic is the audio equivalent of launching missiles.
One last question for you folks. Would there be any phasing issues caused by placing the bass amp right next to the sub in the center in front of the stage and monitoring bass through stage monitors. Would the sound couple, conflict, etc?
If the bass is not in the PA then no to phase issues but could be a conflict with the mix as the person FOH has to work around the what the bass amp directly producing in the room.......but with a reasonable PA that has a sub/subs the bass should be in the mix.

if the bass amp was getting a bit of help from the PA and the amp and PA sub were nearly touching, would there be phasing issues?
I had no idea it was this problematic when I first started playing 40 years ago...get big speakers, feed'em lots of juice, rock'n roll.
Yes. But to what extent, or if you would notice, or if you would love it or hate it is an unknown. So it's a gamble that IMHO is not worth the effort to test.
Your bass is coming through the PA in the subs AND the tops because a lot of what you hear from your bass is the upper overtones. So you will have phasing issues with the tops which are at the sides of the stage. You will probably also have phasing issues with the subs because they are mismatched cabs. Putting mismatched cabs together can have unpredictable results. AND even if you try it and it sounds good in one room, there is no way to know that it will also sound good in another room.
