Hello,

Here is a rundown of the equipment I have:
Mixer: Mackie CF20
Power Amplifiers: Crown Ultratech 1010 (x2)
Graphic EQ: Samson E62 1/3 Dual 31 Band Equalizer
20 channel Snake
JBL speakers (not sure model)(x2)
JBL monitors (x2)

I am the worship leader for my local church. Although I know a little bit about mixing & audio engineering, I am a little confused about this issue. I "inherited" the sound system when I became a member of the church. It is obvious that all of the equipment was installed incorrectly...continue reading and I'll explain how I know this.

Note: All of the cables used to connect things have been ran through the ceiling, so I am unable to get a clear picture of the setup. However, as I previously mentioned, the system is wired incorrectly. When I connect the speakers to the "main out's" on the mixer, no audio is outputted to the speakers, regardless of the level of the main mix. However, when I connect the speakers to the "sub out's", there is audio outputted to the speakers.

Therefore, my question is:

What is the proper signal chain to connect all of this equipment? Where does the Graphic EQ fit in the mix? If I wanted to send the signal from the Mackie CF20 into another, smaller mixer (which has a USB port on it to record), what "output" should I use?
