Reply to can someone suggest a live sound mixer?

I really appreciate some help. Sorry for the long post.

I am looking for a mixer with multiple outputs, one being dedicated sub output.

I did some reading and research and I believe I just want to kill myself now...

For simplicity, lets just say that I have four amps (don't really need to go in to the speakers)

two amps for full range (these amps do have line out)
one amp for midbass / highs (no line out)
one amp for subwoofer (no line out)

I got everything together now, but I would like to improve on it.

The two things I don't like are:

1. RCA cables are used for the source (then, TRS and XLR from amps one and two to amps three and four)
2. No electronic crossover.

I would like to have a mixer that has multiple outputs, preferrably all TRS / XLR, and at least one dedicated sub out or the ability to do an active crossover.

Does this make sense?

So, the outputs would be something like this:

(XLR or TRS)
one stereo or two mono full range
one stereo or two mono high pass
one mono sub

TIA!
