kp3 using send through control room on mixer

[ReekDaddy]

so i have a behringer 802 mixer and 2x-kp3 i also have k-pro and micro korg. microkorg goes into k-pro which goes into first kp3 then second kp3 using send goes into mixer then out of control room back to kp3 .my problem is getting EQ to sound right when it does and i can sample sounds same level in volume i hit effects and blow out my ears then if i go lower you can barely hear effects and when u sample its so quiet its worthless any suggestions? do i need a seperate equalizer?? please help and thanks for your time
