What is the actual watts per channel @ 8-ohms and 4-ohms on the Behringer PMP3000?

Where do you have the gain control set on the Mic channel ?
If you have no issues with either the speakers or the Mic, and the gain control for the channel you have the Mic plugged into is set at a somewhat "normal" position, you might have a problem with the mixer itself.

Absolute maximum is two of these per side. The speakers are 8 ohm and two on each of the outputs would be 4 ohms which is the minimum allowed for the amplifier. You will get about 400 Watts RMS per side doing this. Please note that the stated 1200 watts for the amp is the PEAK (fakey) values put forth in all the ads we get now. With 4 total B212XL's you should be able to fill an indoor venue of about 10000 square feet with sound at the OSHA limit.

Yes, you can put two 8 ohm speakers daisy chain per side MAX. The Speakon should have ONLY two wires on the +1 and -1 terminals unless you are using bridged mode which is NOT applicable in your configuration of speakers. Also be careful is you use any 1/4 inch speaker plugs in the sytem as the SLEEVE, not the TIP of channel A is the "hot" lead... get this to ground someplace and goodbye amp.

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...

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 !!!

You CANNOT power 4 total 4 ohm speakers from this unit without special configuration. The lowest you can go is 4 ohms per side, which would be one 4 ohm cabinet per side. You would have to do a series parallel arrangement with the resources you have... two Peavey's in series and that combination in parallel with two 15's in series...
This is a VERY unsafe configuration with this mixer. ALSO please read my tip on here in regard to PMP mixer grounding hazard of the A channel when using Speakon to 1/4 inch cables.

Frankly, forget about maximum performance unless you want to risk blowing your mixer...

If I were you, I would put the two 15's in SERIES as 8 ohms on one of the channels and the Peavey's in SERIES as 8 ohms on the other channel.

You would be well to heed this warning as I have repaired a bunch of these units. Be careful of any poor speaker connections as there is an insulation breakdown problem in the power amp circuit board if a speaker becomes intermittent. If something fails DO NOT replace the pwer fuse as you will do more damage.

The answer to your question is NO, there is NOT an internal adjustment.

For many mics the trim is used full clockwise. Some higher output mics I use the trims are run at 3 o'clock which is mostly turned up. This is NORMAL for most mixers. If you don't have enough mic gain relative to other inputs, the fault is balancing the other inputs down and using higher setting on your MAIN slider.

If you use 8 ohm speakers then you can expect to get about 200 Watts of audio per side with this amp. You can get about 400 Watts RMS (600 Watts peak) using 4 ohm speakers.

The efficiency of the speakers makes a lot of difference in the sound level output/

The unit should drive 400 Watts RMS into a 4 ohm load per side.

The amount of sound power you get will VASTLY depend on speaker efficiency. You would likely use at least 15 inch speakers with the unit.

The speakers are 8 ohm so you can probably get near the 400 Watt per side when connected to this mixer. You don't need bridge mode to get this and I would recommend not using it anyway. Whatever you do make sure the speakers don't get disconnected when running at high volumes as you will arc out the amp in the mixer... I know this as I fix them... I have two PMP5000's that I repaired. Lots of work to repair...

The feedback is NOT the fault of the mixer or speakers but instead of something picking up sound from the speakers and sending back to the mixer.

The mic must be well in back of the speakers (say at least 10 feet) to avoid this or you need to use anti-feedback hardware to avoid the problem or highly directional close talking mics. Reverberation off walls can also get back to mics and cause problem. I was able to use a wireless Peavey mic which seemed to disrupt the phase enough to never get into an oscillation even when in front of the speakers.

try connecting speakers to another sound source or if you have access to a ohm meter, check impedance of speakers, should measure 4~8 ohms.
