Kustom Profile system one - hints and tips

I have just bought a new Kustom Profile System One - 100 watt P.A. system. I am interested to hear from someone who has experience in initial set up re adjusting the controls to get the best sound for female vocal and acoustic electric guitar. The manual provided only gives basic instructions and leaves it up to the individual to try and work it out. Their web site was of no help for me. I am wanting to get a more mellow,and rounder sound for my voice.
