Re: Allen&Heath XONE92 DJ mixer repair
Hello everyone, just a quick question before I proceed with the pot replacement:
For HiFi gear, is solder with 60% Lead/40% Tin content suitable, or should I hold off on the replacement until I get a more suitable solder of Silver/Copper/Zinc ?

Re: Allen&Heath XONE92 DJ mixer repair
It effects both pots. There is a slight differences between where these ''frequency bleed'' spots are, but it makes sense since they are the most used pots on the entire mixer. I'm guessing one must have stopped working, and then the other one got all the use transferred to it... which is a lot, since this particular mixer is close to 16 years old.
Fully analog ofc.
The pots do seem as if the previous owner attempted at spraying them, since they seemed to be a little ''oily'', and a big dust ball on each of them.......Leave a comment:

Let's say I am applying the HPF. For the first 20deg of rotation, it will work as intended, removing the lows. For the next few degrees of rotation, it will remove even more lows. Then, all of a sudden there is a spot, where all the lows suddenly come back in. If you rotate the pot a little more, they go away as intended.
It's the same when applying the LPF, where at certain spots of rotation the highs will bleed through. I'm assuming it's a faulty pot.
The spots, where the wrong frequencies bleed through, are...Last edited by JohnsonJ; 01-01-2021, 11:18 AM.Leave a comment:

Just an update for anyone reading this post in the future: recapping the PSU did not fix my filter issues, it seems the potentiometers need to be replaced. Will update as soon as I receive and install them.
Voltages were 14.91V and 15.03V, so I would say the repair, although not fixing my filter issues, improved the PSU itself. I used Panasonic FR and Nichicon caps.Leave a comment:

Re: Allen&Heath XONE92 DJ mixer repair
Thank you very much redwire! I will go with Panasonic FR, and I've decided I will be recapping everything.
I will post na update here once it's all done :-)Leave a comment:

The physical height limit is 35mm, so probably 30mm would be the max to allow 5mm of air passage. I think they get too hot, since by design the protective case in the PSU is very small.
For the 120uF, 63V, 105°C, which impedance would you suggest? All I can find on the original part is, that it is ''low impedance''. No specific values given. Is it safer to choose a higher impedance cap than a lower?
I'll submit an order as soon as I know which impedance you suggest I go with, and will post here once it's all soldered...Leave a comment:

Re: Allen&Heath XONE92 DJ mixer repair
Ok, I'll just be replacing C64, C65, C66, C67 (all 4 the same), and C61 and C62. So this removes the issue of finding 3 replacements, just need 2 different types now.
I'm not so sure in using higher voltage rated caps, a quick google search says it might cause problems as you stated above? I definitely want to keep to as close original specs as possible.
I guess what I'm wondering is, if the choice for C64-C67 is fine, if it has a 0.1A less ripple rating?

Re: Allen&Heath XONE92 DJ mixer repair
Thank you very much. That's what I primarily intended to do, but in the old thread (I think 10 years?) it was recommended exactly the opposite, to change all of them.
I'm not sure if it's a ''problem'', but, I noticed that C61 is not the same as C62 and C60. I think it was replaced in the past. That's why I would at least replace those as well.
So would the C64-C67 replacement I linked above be suitable? Even tho it has 0.1 A less ripple rating?
Thanks for the help!Leave a comment:

Re: Allen&Heath XONE92 DJ mixer repair
PS. I forgot to ask about picture number 6. I'm not sure what that part is called, but it seems to have some corrosion there? I'm not sure what that stuff is. Should I try cleaning it?Leave a comment:

Allen&Heath XONE92 DJ mixer repair
Hello everyone.
I'm having issues with my DJ mixer, and after taking it apart and checking everything out, it seems that I need to replace 2 rotary potentiometers for the filter, and that the PSU has some caps burned. Hopefully these 2 fixes will solve my issues.
The potentiometers I will just replace (hopefully the repairman I spoke with will indeed send me the spares, in case he doesn't, I'll update here if we can find a suitable replacement), but for the PSU caps I'd kindly ask you forum members, if anyone could help guide me in the right direction. I'm having difficulty...Last edited by JohnsonJ; 12-12-2020, 12:01 PM. -
Re: New Members - please post your introductions here
Hello everyone, I joined the forum in hopes of figuring out how to fix my xone 92 from 2005. So far, I seem to have found the issue, the only thing left is to ask what I can substitute my components with.Leave a comment:
