A speaker cable was stepped on and came out of amp. Then, immediately put back in. There was smoke. Now it wont power on. Can this be fixed? How?

Yes, it can be repaired. Likely at least the output transistors are fried, possibly the drivers are too. Possible other components like resistors gone, too. Needs somebody that knows amps.

If the problem still exists after trying multiple cables and speakers then the problem is either the jack itself or the amplifier in the unit. This should easily be fixed by an authorized service center.

Plug the guitar on the "power amp in" jack near the "presence" knob.
If you get sound, you have a problem on the preamp. If not, it´s probably on the power amp section.

Its a good start...

Compare the power inout voltage listed on the BACK of the speaker and compare that to your current power supply. You have not told us wheree you are or what your power there is... or the voltage listed on the back of your speakers. Giv us this info so we can better help you. These are expensive speakers to get things wrong...

Without more information of your speakers and amps we can't really help you. The Mackie board puts out line-level signals and that should drive any connected amp or powered speaker to the full capability. Make sure you are using BALANCED interconnect lines either XLR or TRS cables. Use of TS unbalanced cables costs you 6 DB and also noise pickup. Make sure ALL your gear, amps, speakers etc are powered from a SINGLE receptacle or power conditioning module. Normally you will use the AUX outputs of the mixer by way of TRS cables or balanced lines in a snake to power amplifiers onstage which then connect to the stage monitors. If you have powered monitors the returns of the aux to the stage go to the powered monitors. A heavy duty extension cord brings power back from thee stage power to the mixer.

Yes, in bridge mode you will wire ONE Speakon that will have the two speaker wires connected to pins "1+" and "2+". You do NOT need the manual to do this, the info is right on the back of the PMP6000 itself. You will plug that Speakon into channel "B".

PLEASE note that you CANNOT go below 8 ohm speaker impedance. If your speakers are 4 ohm you MUST connect two in SERIES which requires special cables and the speakers MUST be identical. You can connect TWO 16 ohm speakers in parallel by daisy chaining, however 16 ohm speakers are NOT very common. With 8 ohm speakers you can connect EXACTLY one in bridged mode UNLESS you connect four of them in series-parallel which requires special cables and great care. Believe me you do NOT want to have an accident with this amp as repairing is extensive.

Lastly, put the speaker configuration switch down to the bridged mode.

This is how bridged mode works: Sliding the switch down basically configures the two power amps in monaural and one amp is inverted so there outputs are out of phase by 180 degrees effectively doubling the voltage.

Remember that BOTH wires in bridged mode are HOT and grounding one while amp is on will likely blow out one side or more.

Cease using the mixer until it is repaired. One or both of the amps have blown. Further use MAY result in power supply damage. 1 to 6 switching power transistors will have blown and often a Zener diode or two. If the metering resistors smoked, there will be two small surface mounted transistors per channel blown wide open as well. These are all in the HCA2400 amplifier module.

ok, first thing will be the effects processor. look for the "aux sends" output jacks near the bottom center of the rear panel. run a 1/4 inch instrument cable from "aux send" 3 out into the input on the vocal processor, and run another from aux 4, if the effects processor has 2 inputs. then, from the vocal processors output, run 1/4 inch cables back into the "stereo returns" on the mixer, (located on the rear panel on the bottom, extreme left) 2 outputs per input, since its making stereo effects. so, if you ran just send 3 into the processor, you should have a left and right return instrument cables into the mixer for "stereo return" 3 (left and right). if your processor has 2 imputs, and you are using both "aux send" 3 and 4, then you will have to have a pair of cables going to each "stereo return" for 3 & 4. -to apply effects to a microphone(s), you would adjust the individual aux send levels for each channel you want to have effects, and you would have to ensure that the master aux sends and returns are also turned up..

ok, the snake is simple, each xlr (3 prong mic) connector on the snake is labeled, so, just plug each xlr jack into the corresponding channel on the board, and plug the first 2 1/4 inch ends of the snake into the "C/R out balanced" outputs on the board, located on the rear panel, up and to the left a bit.

at the stage end of the snake, ues a 1/4 inch instrument cable to copnnect the first 2 1/4 inch jacks on the snake to the left and right inputs of the crossover. then, from the crossover, connect the sub power amp to the "low" stereo outputs of the crossover with instrument cables, and connect the main speakers amp to the "high" stereo outputs of the crossover with instrument cables. if its an adjustable corssover, you will want to have it crossed over somewhere about 80-120 hz to allow only the lowest frequencies to the subs.

now, from the amps to the speakers, we ane going to have to use heavier 12-14 gague SPEAKER CABLES, instead of light gague instrument cables. hook the subs up to the stereo speaker outs of the sub amp with speaker cables, and do the same for the main speakers.

There are many things, including hardware failure to cause this.

Make sure that the PFL buttons are ALL up. The LED indicators on the right are shared with solo channel and main output.

REMEMBER that the MAIN 1/4 inch jacks are TRS balanced and plugging a mono cable into these OR st the other end plugging into a MONO will short out the balanced line drivers. Since this also goes to the power amp, that can ground out the signal to the amps. All the other 1/4 inch jacks are pseudo balanced and mono plugs will not cause a problem other than possible hum or noise levels.

Do you get anything out of the PHONES jack?

Note that the standby switch must be UP in the upper right corner... it kills the first 12 channels. ALso with two speakers make sure the MAIN slide switch is in the MAIN A MAIN B upper position.

Start with all your PAN controls at 12 o'clock.

I have repaired two of these units and a PMP3000. Great caution: NEVER pull or insert speaker cables while unit is on. Great damage can be done. IF the fuse blows do NOT replace it!!! Get serviced immediately as replacing the fuse will likely do more damage. The worst damaged one required replacing around a dozen transistors and other components.

The power amps in these have a habit of arcing out... NEVER store in a high humidity area!!!

Try a set of stereo headphones plugged into the L and R MAIN out 1/4 inch jack... If you have audio there your power amps have failed or the +/- 85 volt supply has smoked.

A VERY common problem working on amps is to miss putting a cable on. Sometimes a small cable "hides" and we forget to put it back on OR it has gotten pulled off and we didn't notice... AND sometimes theyhave wires going through a hole in the cabinet to connect to a speaker and the wires get pulled a little and pull off the speaker where we can't see them... what a pain... these things aren't made for easy service.

When handling the chassis to assemble it is EASIER to lay the cabinet on its side to control the heavy amp.
