I will be using the following for an average size bar, maybe 200 people tops. I have a behringer pmp3000, a 600 watt crown amp, a 600 watt carvin amp, 4 monitors and 2 peavey international seies III speakers.
my problem is in finding a best hook up for this. Some people tell me that the powered mixer will not power as much as the crown will and that I should use the crown for the mains. question is this, how do I use the mixer amp to power the monitors and how will the controls on the board work.
I would love to use the board to power the mains because the controls will be used for what they are marked as, but if I change things I am afraid I will have to re-lable knobs and fader controls and I do not want to lose the two different monitor sends.
According to the specs on your Behringer you are getting 600 watts per channel. That is all you would get from your power amps if you use both of them. The mixer should be enough for what you intend. You can use you monitor send and run monitors through either power amp and have plenty of monitor. So my answer is stick with the board.

Good luck......Behringer does not release schematics....you will have to do it without them unfortunately.....unless you can find somebody who has them...Check for a forum on the net for Behringer equipment...you might be lucky to find something there.
Well... you probably won't like this, but here is some info: In bridged mode, a different Speakon to speaker cable is required from only the B... it is wired differently and you can only use one of the plugs. The speaker or speaker system CANNOT be less than 8 ohms in bridged mode... this precludes using speakers in parallel or multiple speakers that are less than 16 ohm impedance... such speakers are NOT commonly available as most are either 4 or 8 ohm. There is a slide switch for bridged mode on the face of the mixer. Next thing you won't like... The 1200 Watts specification is PEAK power, NOT RMS... You can get 400 watts RMS per side USING 4 ohm speakers. If you use 8 ohm speakers, each of those will get 200 watts. I use this mixer myself and ALSO repair them. The voltage swing at the outputs is about +/-60 volts MAX (peak). This is about 40 volts RMS by the time the circuit LOSSES are taken into account. Across a 4 ohm speaker you get 10 amps times the 40 volts or 400 watts. Across an 8 ohm you get 5 amps or 200 watts. The voltage rails in the switching amp are +/-70 volts DC so these are reasonable values. Bridged mode just uses both sides of the amp driven in opposite directions for higher voltage out BUT you have to use no less than a single 8 ohm speaker so there is NO advantage to bridged mode power wise. IF YOU NEED more power, use extra speakers from an additonal amp driven by the 1/4 TRS mains output jacks OR use additonal POWERED speakers driven from the same jacks. Please read my tip about the hazard regarding the SLEEVE of the cahnnel A cable when using Speakon to 1/4 plug cables being the HOT and the tip being the cold for channel A. Ground the sleeve accidentally and goodbye channel A amp...
I am not sure how you are measuring the power output to verify it is less than 200 watts. With a true RMS voltmeter you should see 28.28 volts RMS across a net speaker load of 4 ohms. If you use only one 8 ohm speaker, you will get 120 watts. If you are getting the 28 volts there is nothing wrong with the amp. You MAY have blown the speakers OR not generating much bass due to processing in an EQ. I assume you are using at least 15 inch speakers if you want to feel bass. Look up your speakers specs... you will need speakers capable of 32 Hz to feel much. With this amp your speakers should have aa total rating not less than 400 to 600 peak watts or around 300 watts RMScontinuous power rating. Using a lot of high end EQ will keep the amp busy at the high end and reduce the power available at the bass end.
The JBL EON 305's are 8 ohm speakers. The PMP5000 wi;; produce 400 Watts per side into a 4 ohm load (600 Watts peak). Into your 8 ohm speakers, the peak current will be halved while the voltage remains the same so you ACTUAL power per side is 200 Watts. It is hard to know how much you expect to get out of the amp. This power would fill a venue of at least 2000 sq ft. If you need more sound, try borrowing another 8 ohm speaker for each side and parallel them with the EON's as a test. That will double the power and add 3 Db more of sound. Your main slider should be around unity typically. This amp is a class D switching type (very efficient) and runs on +/- 70 volt rails. giving about 45 volts RMS output. At 4 ohms, this is just over 10 amps giving 450 Watts... at 8 ohms this is around 5 amps or 225 Watts.
Please read my tip on Fixya about the ground hazard of channel A when using 1/4 inch cables out of the PMP units... essentially the BARREL of the connector from channel "A" is the HOT,... NOT the tip of the PLUG. Ground the barrel IN ANY WAY AND YOU FRY CHANNEL "A" AMP !!!
