Allen & heath xone 42 fader problem channel 1

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.

You've pressed the "solo" button by accident.

If you pull the knobs off, you will find lock nuts under them. You could tighten them up. See if the knobs have set screws on them to lock them in place before pulling them off. On Allen & Heath, I don't think they do but, just in case.

If one of the channels on your Allen & Heath XONE:42 mixer is not functioning properly, it is likely due to a problem with the channel's internal components or electronics. To repair a blown left channel, you will need to disassemble the mixer and locate the source of the problem.

Here are the general steps you can follow to troubleshoot and repair a blown channel on your Allen & Heath XONE:42 mixer:

Disconnect the mixer from any power sources and remove any cables or accessories that are connected to it.

Carefully disassemble the mixer, following the instructions in the user manual or a service manual if available.

Once you have access to the internal components of the mixer, carefully inspect the left channel for any visible damage or problems.

If you find any damaged or faulty components, you will need to replace them. You may be able to find replacement parts online or through a specialist DJ equipment retailer.

If you are not comfortable with disassembling and repairing the mixer yourself, you may want to consider taking it to a professional repair service. A technician will be able to diagnose the problem and repair the mixer for you.

Keep in mind that repairing electronic equipment can be complex and requires specialized knowledge and tools. If you are not familiar with electronics repair, it is recommended to seek the assistance of a professional.

Hi,

based on page 33 of your products phantom power is not supported by the xone 92, so it would not be recommended to connect a microphone that depends on such power.

Thank you.

Does the left meter do the same thing? If the meter matches the right one, I would suspect the volume potentiometer on the powered speaker. Try exercising the volume knob. There might be some oxidizing on the potentiometer.

NEVER, NEVER put contact cleaner into the faders!!! It removes the lube and the faders will be damaged in short order. Try using CRC226 available at Home Depot in the electrical dept. Use ONLY the CRC226 as there are other CRC products that are not applicable. Squirt some in the center of the slots... not too much and work the sliders... if they improve try a little more... If they are still bad, replace the sliders... it is a MISERABLE job involing removing mass number of knobs, screws, etc... and then getting/finding the replacement fader control. Usually I get them from Digikey.com or Mouser.com and sometimes the actuator tab has to be trimmed to length with tin snips so knob will be at right height. The fader must have the same resistance and TAPER as the original as well as mounting tabs.

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 .

You may need to trace the circuit and locate the loose connection. The service manual is available for free with Manualslib com. You may download it .

There can be any number of reasons for this problem - solve it diagnostically by starting with something that you know is working and work through systematically to the other end.

1. Test a microphone on a separate amp to make sure it works okay. Check amp and speakers working. Check that all output cables from mixer to amp are working by testing separately.
2. Plug microphone into a channel on mixer. Also plug in headphones and turn headphone volume control up.
3. Make sure input sensitivity knob is turned up a bit (say half way) and main output faders (yellow) are up.
4. Check that channel is turned on (little button just above the channel fader- needs to be pressed down)
5. press pfl (pre-fade listen) button (next to button to switch channel on)- do you get any sound on main output or headphones or any indicator lights on mixer to show signal is getting that far (eitehr the individual channel metering lights or the main ones in the central section)?
6. turn off pfl - make sure channel fader (slider) is up - normal position is ) - about 3/4 of way up. Check lights again on individual channel and main output section - any signs?
7. Is the sub mix button for the channel pressed down - in which case you will need to bring sub mix (red) output faders up as well as main faders.
8. If you have got signs of signal on the individual channel but not main see if the channel has been routed somewhere odd (like a subgroup of channels).
9. Plug a working amp and speakers into one of the auxiliary outputs and use the relevant auxiliary send knob (on each channel just above the faders and pfl switches) to pan some signal to that auxiliary out - do you get anything? There is also a headphone socket for listening to the auxiliary channels (with a selector switch /knob to determine which one - make sure it is in the right position) try listening to the auxiliary output with headphones - anything? If yes the problem lies in the main output section.
10. Check that there is not a jack plug in the insert socket (to route signal through an external effects unit) without a matching return jack being plugged in - if appropriate is relevant effects unit switched on and correctly set up - if unsure remove the insert plug to take it out of the system.
11. Make sure any mute buttons are not switched in on main outputs.
