After a gig, I accidentally plugged my monitor sends 1 and 2 on my PMP5000 to the outputs of an external power amp, and powered it up.... I realized my mistake, plugged it in correctly, and now the monitor 2 send is dead, and monitor one is very weak. Also the 2 effects channels are dead....what did I do? and how do I fix it?

I'd need to know what mixer you have, to know if there is a [line out] connection socket and an [internal amp in] connection socket.

"each with own poweramp" I presume means the ep1500's and NOT that the speakers are active (ie containing amps)

***If any of your speakers are active, ask the question again, with more detail.***

So if all your speakers are passive, I offer the following.

I assume there is [effect send] and [effect return] on the mixer

effect send>quadraverb>effect return

mixer line out > eq > compressor > sonic maximizer > crossover

sub output of crossover> amp > sub
high output of crossover to mixer's internal amp input
mixer's speaker output > main speakers

monitor output > other side of eq (>other side of compressor if desired, but use sparingly ) > other side of sonic max if it is true stereo , otherwise skip > amp > monitors

If your mixer doesn't have an input to its internal amp, we are "back to the drawing board"
With questions like this it pays to give as much detail as possible; model and make of each component etc
I have done my best with the the info you have provided.
Don't feed amp outputs into powered speakers

Yes, you can use both the main1 and main2. They are independently driven and please note that they are PSUEDO balanced drives... that is the cold side of the balanced line is NOT driven as a complement, but is merely returned to signal ground by a 120 ohm resistor. This CAN cause hum problems or noise pickup depending on the connected equipment and ground loops. Best to run this into amps/speakers thaat have TRUE balanced inputs and also keep the power source the same for all devices.

Yes, you blew out components associated with the monitor sends. There are several components including an RF bypass to ground and the driver IC, IC8 and a decoupling electrolytic cap. The repair is going to be extensive as it is likely you will have to remove ALL the panel knobs and screws to free up the circuit board for repair. I have worked on several mixers and have three of the PMP5000's myself and dread removing the main board. I am going to suggest something you might consider: Many of the PMP's fail either in their power supply or one of the amps. Due to the repair cost I would consider getting a scrap PMP with this problem and swapping out the panelboard for yours. Often you can get one with blown supply or power amp for around $200 and I suspect a repair shop is going to charge at least that to repair your unit... Then you will have a spare parts bucket as well.

Very strange behavior. Knowing the electronics within the unit, I see no reason that moving the main volume could restore operation. i tend to think that is a coincidence. Possibility the vibration of moving the control caused it to operate again. Do read the tip about PMP mixers I posted on Fixya about the hazard of channel A output if you use Speakon to 1/4 inch cables or adapters. If this happens again, try headphones and see if the signal still comes through them. There is an electronic fuse that can kill output IF the output current gets too high, but for that one you have toturn power off for some time for it to reset. Since you did not turn power off per your posting, that possibility is ruled out. Normally the sliders will NOT fail midstream and would be restored with any slight movement.

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 !!!

Make sure the appropriate channel rotary knob MON1 knob is turned up for the channels you want into MON1. ALSO test other channels if they can be sent to MON1. The MON jacks are TRS with the tip as the hot and the sleeve as resistor to ground.

Hopefully you have used good practice and have ALWAYS powered whatever you are driving from the MON1 out from the same receptacle as the PMP5000. If not, ground bounce MAY have destroyed the driver in thee PMP5000. They USUALLY don't tell you these things in the user manuals, so it is up to us electricaal engineers to educate.

FIRST plug in a set of headphones and see if sound comes out (it will only be one side and fairly low volume, usually the left). If it does, then cabling and whatever amp you have for the MON1 has a problem. I have schematics and can help you troubleshoot a bit.

Also PLEASE read the tip I have posted on here about a grounding hazard of the A channel when using Speakon to 1/4 inch cables.

It is NOT clear what configuration you have set up and what you consider the MONO output is, whether it is the power amp MONO side output or the line level MONO 1/4 inch jack on the top of the unit (this jack is NOT speaker output). If you can run normal stereo speakers using both sides of the power amp in the AB mode, the problems you are having is pilot error.

REMEMBER the main out 1/4 inch jacks are BALANCED TRS jacks... DO NOT put mono plugs into these.

A WARNING: If you use Speakon to 1/4 inch speaker cables, remember that the BARREL of side A is HOT, not the tip!!! You can fry the amp if you inadvertently ground that barrel someplace. (Side B has the barrel grounded) This information is NOT readily available in the manual and results in many a blown amp. They do this to implement the "Bridged" mode easily.

I have schematics and can unravel most any problem you are having.

Do you mean the SPEAKER mono output or the top mounted 1/4 inch jacks?

The A side power amp is used to drive monitor speakers and the B side the mains.

All other connnections of speakers require amplifier OR powered/active speakers.

Without knowing how you have your monitors configured it is hard to analyze what you have posted.

In brief, SW3 on the schematic that selects MAIN L and MAIN R in the upper position, MAIN and MONITOR in the middle, and bridged in the lower is used to configure the internal amps.

In the upper position, the amp power outputs come from the mixed stereo bus and are simultaneously controlled as a stereo signal by the MAIN slider.

In the middle position MAIN and MONITOR, the left amp receives the signal from the mix bus and is controlled by the MAIN slider. The MONITOR output from the other side of the power amp is controlled ONLY by possibly the "MONO" slider.

The schematics are hard to decode and what is needed is a signal flow diagram.

For my uses, I don't try to use splitting the power amps between mains and monitor but prefer to use the mains together with SW3 in the upper position (Note your 27 may be refering to the user manual designation for same switch). I then use another small amp from the 1/4 inch MONITOR jacks whcih are under control of the MONITOR sliders.
Please note that the MIX for these two MONITOR channels is controlled by the MON1 and MON2 knobs for each channel.

Assuming you are using BOTH power channels for your main speakers, you MUST use external, additional, amplifiers for the monitors. There are ONLY two power amps in the PMP5000.

The other option is to run mono for the mains and use the second power amp (comes out on the Speakon connectors) to drive the monitors. For this, the little slide switch has to be on the middle position.

Doing this, you have to adjust the monitor volume controls for each strip.
