PMP Mixers hazard - Behringer Europower Pmp5000 Powered Mixer Pmp5000

Your PMP what? Is this a Behringer?... and if so what model?... If it won't power up, for goodness sakes do NOT replace a blown fuse as additional damage usually results. Get it serviced... if under warranty, then exercise the warranty. If it is a BEhringer, then also read my tip on Fixya tips regarding PMP mixers and a hazard of using 1/4 inch plug speaker cables or adapters.

What is up is one of the two power amps is blown... I know this problem... It is USUALLY the rearmost channel which goes to the left Speakon faacing the back. Weak insulation between layers of the multilayer circuit board arcs and fries three transistors and a diode and sometimes a few more components. It takes a lot of skill to restore the module and is beyond most repair shops. A whole new module costs about $155 from Full Compass. The amp is an HCA2400 module, but you MAY need the Behringer part number to order it from Full Compass. Also please read my tip on Fixya for PMP mixers regarding the hazard when using 1/4 inch plugs from the Speakon connectors... the Channel A sleeve is the "hot", not the tip and if you ground the sleeve, goodbye channel A...

Using TRS balanced cables, come from the main outputs L and R on the top of the panel to your external amps. ALSO read my tip on Fixya about hazard of channel A on PMP mixers.

The speakers would receive about 250 watts max each from the PMP3000 since they are 8 ohms.
That is quite a bit and should fill a 1000 square foot venue with plenty of sound. The type of program material will affect what sound level you can get to. I would recommend you procure a sound meter and measure the sound level. You should be able to get 90 to 95 DB out of these easily. I use a PMP 3000 with two Peavey 15 inch with horn cabinets and can get 98 DB in a 30 by 40 foot room easily. You need to respect the OSHA sound level limits and a sound meter will help you comply. The 12 inch speakers would probably be too small if you are running a lot of bass through them. Please read my tip on Fixya regarding a hazard of the PMP mixers. Essentially, when using 1/4 inch adapters or plugs from the speakon connections of the PMP's, channel A sleeve or barrel is the hot whereas the tip of channel B is the hot. This is not documented in the user manual and if you inadvertenly ground the sleeve of channel A you will likely blow the amp.

The amp module has likely blown. Repairs can be exetensive within the module. Try cycling the power as there is an overcurrent sensing in the amps that locks the switching signal off. Let the unit remain off for several minutes and retry it. This all assumes it has worked before and the cables are good. Also please read my tip on here about PMP mixers regarding a hazard on the A output when using Speakon to 1/4 inch cables. The A output s;leeve of a 1/4 inch jack is the HOT, NOT the tip of the plug, unlike the B output.

Assuming your PAN controls are all at 12 o'clock, it looks like you have popped one side of the power amp. Please read my tip on here about the HAZARD on the "A" channel of PMP powered mixers. Essentailly, if you use Speakon to 1/4 inch cables or adapters the BARREL or the SLEEVE of channel "A" connector is the HOT side of the speaker and touch ground with it and goodbye Channel A side amp. They don't tell you about this in the manual. The tip of the plug is e cold side of the amp output UNLIKE channel B where the tip is the hot side. They do this to make it easy to implement "bridged mode".

Reepair of thes amps takes skill. This likely has the DPA300 module in it and you will find one side fried switching transistors and often a Zener diode. Sometimes the circuit board will have arced and be damaged.

There really ISN'T and "advanced" manual... Everything you need to know is in the user manual that comes with it... Service manual with schematics will not give you much you can use unless you are into electronics detail.

PLEASE read my tip about Behringer PMP mixers on here regarding a hazard if you use Speakon to 1/4 inch cables or adapters. Essentially, the sleeve, NOT the tip is the HOT lead for a speaker on channel A. Ground it inadvertently and goodbye channel A amp.

Be VERY careful of speaker leads with this amp as it is easy to pop a channel IF a speaker comes loose or shorts. Loop cables through the handlesto avoid cables being yanked out or breaking plugs.

The passive speakers connect to the main outputs using Speakon connectors on the back.

You will use Balanced connections (TRS) to the main L and R connections on top to the active speakers. Daisy chain 3 active on each of the L and R top connectors.

You can download a user manual if you don't have one.

ALSO PLEASE read my tip regarding a hazard when using Speakon to 1/4 inch speaker cables on channel "A" in the FIXYA tips for PMP mixers. The barrel of the channel A 1/4 inch is the HOT side of the signal to the speaker instead of the tip.

Assuming they are ALL mains and not for monitors connect this way:

Connect the passive to the A and B powered outputs. Please read my tip on Fixya regarding hazard of grounding speaker leads on channel A of PMP mixers.

Connect each pair of active speakers to the Main L and R 1/4 inch jacks using TRS balanced cables. Power these speakers from the SAME receptacle or source, even if it means running an extension cord to your mixer from where the actives are plugged in. FAILURE to do this creates a hazard of ground loops and ground bounce that can damage equipment. The Main L and R 1/4 inch jackls can drive more than one active speaker... these are line level signals. Make sure to use TRS balanced cables for this.

First thing is to read my tip regarding a speaker polarity hazard of the PMP mixers.

Second thing is to VERIFY speaker cables are properly connected.

If you are using in stereo mode set the slider switch to MAIN L/Main R.

describing all possible configurations is not possible on here, but read your manual with this. If you don't have a manual, download one for free.
