Ok, I have a peavey mentor and a dbx 231 dual equalizer. Right now I am using one channel to the mains and one channel to the monitor. Can I use the mentor the same way channel 1 for the mains and channel 2 for the monitors? Or do I use the eq and mentor for the mains and use the mixer onboard 7 band eq for the monitors? Just want to us it to its full potential.
