Usually this problem happens due to bulging of filter capacitors in the Power Supply Unit. identify and replace faulty capacitors with higher voltage ratings to fix this problem. Replacement of the capacitors is very easy if you have repair experience or at least soldering experience.

If you use analog outputs and inputs try to clear of it really is your mixer and not one of the inputs. If the inputs are good your mainboard could be a bit dusty or you have a loose contact. If you have a mixer with internal interface your audio stream from your computer might be the problem.

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 .

Probably the on-board voltage regulators. Little square thingies with three feet. LM1508 or LM1509 or so. Measure the voltage on the third foot and see if they are working. Be good.

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.

I Have a GL2400 Allen & Heath Console. The other day we were working out doors at a Festival and all of a Sudden I stopped receing signal to the Console. I tried all chanels and got the same result. I...


I will ask a question: Did you remember to power ALL inteconnected equipment from the SAME and I do meanALL and SAME receptacle or power conditioner module? If you powered your stuff from several receptacles in a large venue, likely ground system bounce has caused damage. I don't know what you mean by "dont get any signal in."... explain that... There are tests to run to isolate the problem but if you got hit with ground bounce transients you could have major damage. That is a big board for an outside venue so you might describe what you had configured from mics, etc. to speakers. ALL professionals know to run power back from where their amps are to the mixer alongside the snake. I will give you points for carrying a spare... ALWAYS a good plan as electronics DO fail and of course at the worst time.

I would like to buy a case for The Allen & Heath ZED-436 is an audio mixer that gives you 32 mono inputs plus 2 dual stereo channels. Which one do you recommend that can fit it well.Please send me...


Cases are being sold on Ebay, new, from several sources, and if you can't find one specifically listed for your unit, contact the sellers as they custom build them. That is a big unit... expect to pay around $150 to $200 for an ATA type case for it.

Here is an example for a Heath/Allen 420. http://cgi.ebay.com/ATA-CASE-ALLEN-HEATH-ZED-420-ZED-420-ZED420-MIXER-/400127078772?pt=LH_DefaultDomain_0&hash=item5d296eb174

I have bought from them before myself and there are others on Ebay so shop around... You can contact the companies and ask for a specific one and DO compare the size to your unit that they specify as all the companies do not accept returns...

Hey tifly415, did you ever fix this problem? My church has the same mixer and last night it did the same thing twice during a congregational meeting. No fan noise, but the meters all peg and we get this horrible descending squeal which gets louder as you pull the faders back in a moment of sheer terror and panic. Power it off and back on and it's ok for a while then it happens again. It's happened to me a few times during rehearsals in the past and it definitely is not mic feedback because no one was near the console or doing anything at the time. It seems to be totally random and unpredictable.

I, too, suspect a power supply problem, but it never seems to happen when my troubleshooting gear is nearby. The only thing unusual yesterday was that the mixer was left on almost all day, so it may have been warmer than usual.

Anyone else have the same problem, or better yet, know of a solution?
