Zuki I have been doing this for 5 years now I find with powered Sprakers they are very true much faster set up go direct from keyboard to powered speakers

qsc K8 set up in 10 min and ready to go

mic i use keyboard xlr hook up on Genos EQ if you need any use keyboard it is realiy a mixer too the nice thing about using Mic set up on keyboard tyou can use voc harm and control you vol very easy no extra cords tables ect with mixer also if you are using IPAD the go thru st inputs and you have control of that too if I am using guitar pedal i use bluetooth from pedal the Ipad

this is all I need

very seldom use mixer only time I do is if I have multiple players then I use mixer

other wise leave it at home and dont look back
