I get a static buzzing noise out both speakers. it stops if I hold the plug cable or master out cables? turntable wires are grounded. help!


If this is stopping when you grab a connector then you have a bad solder on the connector. a short or break in the wire or a ground is bad.

Left speaker not working, system crackles if left side is active, alright when left side shut down.


Get a meter and check the resistance on the speaker. Looks like a speaker may be blown but with the description of the crackle noise from the slide controls you might have a bad pot in the unit or the pot has come loose from the board. This could explain why the speaker blew out

Allen & heath xone 42 fader problem channel 1


Hello,

Carbon track on fader 1 is open because of wear or just broken, if you are getting sound then the ground carbon track is out but certainly the problem lies in the pot.

How do I fix a blown op amp on fender hot rod deville 2x12?


Unless the person that analyzed this problem used an oscilloscope and did detailed troubleshooting, I would NOT jump to the conclusion that aan op amp was blown BASED upon my looking at the schematic of the unit. There are MANY components involved with the overdrive channel, including relays and other transistors and components. The most probable caause would be that 1/2 of the V2 vacuum tube is burnt out. Test by swapping V1 with V2. If NOTHING works, then replace the tube that is NOW in V1 as the second section of it has a burnt out heater. Also a bad potentiometer for the OD channel would be a suspect. A VERY common problem is broken solder at pot terminals. Try plugging a set of headphones into the preamp output. See if you can hear sounds in bothe OD and clean channels. Note you will only hear sound in the LEFT headphone as the preamp out is MONO. MOST of the three op amp chips would NOT kill the OD signal if they were bad.

One side of my europower pmp 5000 is out, the other is fine.....what up?


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...

Hi I got PMP3000 and all of a sudden in the program smoke came out of the unit and I unplugged the Mixer...I have given it to repair and they saying the Main power SMPS has blown out..they charging too...


Sorry... you likely have one of the power amp channels bad as well. One does NOT replace the power supply, instead repair it. You need a competent repair shop. I can tell you what parts are blown on the supply. They cost about $30 max for parts to repair the power supply. There usually is about $15 of parts blown on the amp that caused the problem and significant labor to repair the amp portion. If the smoke was dark or heavy, it was likely from the 0.03 ohm metering resistor on the bottom of the amp circuit board that caused the original problem. If one replaces the power supply and turns power on they will find one side of the amp doesn't work and MAY blow the power supply again immediately. I have repaired several of these units and have walked others through the repair sequence as well. You can contact me directly by email for more info if you need it. Unless you can find a competent repair shop that replaces components, including work on surface mounted boards, the cost of the module parts AND availability will preclude repair. The amp module is another $155 after the power supply is repaired if a channel is bad and one chooses to replace rather than repair.

I have an allen and heath Xone 22 Mixer. Its great, except due to the lack of a power switch I pulled the ac adapter/power cord out too many times and now it has a really bad, loose connection. It works,...


Usually the connector that is board mounted is the problem. I would OPEN the unit as there may just be broken solder at the connector inside. If the connector requires replacement, find one at Digikey.com by searching for "power connector coaxial".

Hint: In the future install one of those little lamp switches that are in a little plastic box with knurled knob sticking out the sides. ONLY break ONE wire from the adapter to avoid getting the connections reversed. Since the wires are smaller than lamp cord, tack solder the wires to the piercing points of the switch .

Mic channels 2 and 3 don't work no sound. mic channels 1 and 4 work okay as well as inputs 5-12. how can i fix this??


There is an internal f ailure and the unit will require servicing. To get by until you can get it fixed, you can get line transformers that will allow the mics to be used on the higher channels.

If you have inadvertently plugged a source into the :insert" jacks of these bad channels by mistake, that may have blown the input op-amps.

A lot of dis-assembly of the board must be done to get to the parts to repair.

Another possibility is if the sliders have gone bad... SAME prognosis for repair.
