Behringer Pmp3000 16 Channel Audio Mixer Questions & Answers
How to I use 2 additional qsc 500 watt power amps to push 6 jbl225x (4) ohm cabinets. I am running unbalanced stereo.
Thanks,
William
You don't say which QSC Amp. Assuming it is one that can only drive down to 4 ohms you are going to have to run a pair of the jbls in series for each channel of one amp (making the impedance 8 ohms for the pair) and run the other pair from the channels of the other amp. Running unbalanced is not a problem except for interference but you don't say what the source is. If you have more than one output (aux or sub bus for example or poss even a monitor output if you're not using it) it may be beneficial to take one amp from there as you will have some control over the relative levels from the mixer. Otherwise you'll just have to parallel the amps.

How do you connect tape deck to pmp 4000
Hi, use the RCA/Phono connections for the Tape In & Out. The level will be set by the Master/Main fader. If that is not so convenient (& assuming it's a PMP4000?) there should be a "Main 2" output & connections with the level controlled separately to Main 1 via a Knob / Rotary control over to the right above the "Mono" fader... Hope that helps... Good Luck!

No audio from main speakon outputs A and B
Hi, I think in most amps switching to bridge mode simply means the amp supplies its total power through the left channel only. It's the best way to use all of your amp's power but nothing comes out of the right channel. Having speakers connected to both channels would simply mean that only the Left channel works, it would not blow it. Some amps have the speakers wired to binding posts and this varies according to whether you want mono, stereo or bridged. I can't help with the power board sorry

How to hook up passive monitors to a powered board
As opposed to front of house? If you want separate amplification of a monitor system then use either the aux send channels or sub-channel outputs or control room outputs (but check these are not amplified already) connected to a separate amplifier to power your passive monitors

My behringer pmp3000 doesn't seem to have much
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.

HOW DO I HOOK UP PASSIVE MONITORS TO BEHRINGER PMP4000
If you are using the amp in stereo mode, then you will require a separate amp for the monitors and the input of that amp are taken using BALANCED TRS cables from the monitor jacks. If you are using the amp as MONO and monitor, then connect NO MORE than two 8 ohm speakers to the Speakon plug on the back labeled for use as monitor. Refer to your user manual... they have detailed photos of the connections. If you lost your manual, you can download another from the Behringer site. There are settings you need to do to configure the unit after connecting your speakers. The small slide switch has to be set to the center position for Main/Mon. Make sure it is centered as many people have had it slightlyu off and the system will NOT pass audio. You need to set each channel "monitor 1" level control to send the monitor signal to the MONITOR mixing bus. You will then use the MONITOR 1 slider to control the amount sent to the monitor. Be VERY careful of grounding the sleeve of 1/4 inch jacks that originate at the Speakon power amp outputs as the SLEEVE of channel A is the HOT side and you can blow the power amp for the channel... it is EXPENSIVE to repair.

Intermitant problem , now working fine ,
Check that speakers are NOT less than 4 ohms. Swap speakers and verify problem stays on same channel. If it mives with the speaker you are going to be replacing the speaker. There is an electronic fuse that senses excessive current and locks the channel off until you cycle the power off and on. Also there are some older speakers with built in volume controls that this amplifier does not like.

What is the actual watts per channel @ 8-ohms and 4-ohms on the Behringer PMP3000?
Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board.
This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side.
You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine.
For the record.....you could run one speaker per side no problem....just lower power output.
