How do i connect focusrite to europowered pmp4000

Question edited for maker.
Question moved from Musical Instruments to correct category.

Running a 1/4" cable has no bearing unless you are trying to run a hundred yards of cable. Check your plugs wiring and connections to the unit. Here is the manual.

Yes you can, but the questions is should I. the answer is no, unless you have the money to new equipment. Why would want to connect another amp? If some tells you can do it ask for a deposit equal to the price of new equipment.

In my opinion, due to the physical appearance of pmp4000 and pmp3000 look the same, it will most likely also have a common circuit and parts list (at least, most).
Usually Behringer (and all the manufacturers), with the same series / sequence, using the same circuit, the difference is the number of channels only. You can compare the parts list on PMP3000 schematic, with your PMP4000.

Hope this helps.

You will need to give more information for a proper reply, which unit you have and what you want to do with it, what into it and what out etc. In principle you can treat it as a pre/post mixer using it's ins from either the aux or group outs of the mixer or conceivably the inserts depending on what you want to do. You could use it in front of the mixer or as an adjunct. Please tell me what you are trying to do.

The PMP has an electronic overload protection. If you overload one or the other of the outputs, it trips the protector and you have to cycle the power off for a bit to reset it. You haven't mentioned what speakers you have. Be aware that the impedance can be no lower than 4 ohms on either channel. In addition, I have seen some particular speakers that have transformer attentuators in them that this amp is NOT happy driving. You could not attach more than two 8 ohm speakers to each of the outputs without tripping the protector.

At two months, exercise your warranty NOW...

Look for numbers on the chip... It appears that in other gear that I can get schematics for Focusrite likes the NE5532 and the NE 5534 chips for op amp service.

I assume you are using condenser mics as you would NOT be using phantom power with any other type connected or other devices plugged in while you have phantom power. It is important to have ALL interconnected equipment, including the computer, powered from the SAME receptacle or power source. Make sure the power supply you are using is SPECIFICALLY for the unit from Focusrite as some supplies have filtering within the wall transformer module and others do not. The power supply MAY be generating magnetic fields... try moving it around and see if hum is affected. The capcitive coupling in a power supply can let in higher frequency components from lamp dimmers. Make sure you have no lamp dimmers anywhere near the equipment.

You would get about 200 Watts RMS per side using 8 ohm speakers. "Not much volume" is very relative. With the two 12 inch speakers you should be able to fill a 600 to 1000 sq ft room nocely.
