I'm a noob when it comes to live sound gear.
You got the idea... Running live sound is a careful balancing act between system sound and EQ for gain before feedback. If you cut too many frequencies, it won't feed back, but it also might not sound very good. When you boost the bands, feel how fast it feeds back. If you hit a frequency and it rings hard instantly, you need to cut a lot. If a frequency takes awhile to start to ring, leave it be...

Do this and you'll get a lot more gain before feedback in your system.
