    Behringer xenyx x1204usb mixer

    Hi, I have few questions


    1. few of my pots on mixer are turning so hard, I tried to clean them and spray some DeoxIT Fader spray in it, but it didn't help. Is there any way to put some grease inside that pots whole that is on the side instead of spraing in it ?

    2. Or is it just simpler to replace them all with same ones ? I am not into pots, so am I able to put some better quality ones or it needs to be same one as they were default ?

    Ok corrected list ... (taking it that the 6pin pots are 12mm between the 2X "snap in" securing tabs on the pot bases) that's the most common size:


    B503 = B50K (6pin with midpoint) use for headphones & low, mid, high EQ = https://www.aliexpress.com/item/1005007343612656.html

    B503 = B50K (3pin with midpoint) for FX = https://www.aliexpress.com/item/1005006554255808.html

    AC103 = AC10K (6pin with midpoint) for "balance" = https://www.aliexpress.com/item/1005008338040792.html


    Always click on postage options and choose "Aliexpress standard delivery" and you should receive them within 14 days ... other options can take months...

    These are all from the same trader you might get a cheaper deal by contacting them and asking for consolidated postage ... (Always use Aliexpress standard delivery though)...

      you gotta clean the shaft as well, not only the bottom. I would take it out and stick it in a ultrasonic cleaner with hot water a little bit of IPA and Dawn dish soap. Dont forget to work the pot and flush out all the old crap. This mixture cleans sugar up like nothing. Dry it with 99% IPA then relube the bottom with Deoxit and the shaft with some thick oil that has PTFE properties.
      I am guessing there may be some spillage inside the shaft as it usually is with mixers. I only swap out pots if they are beyond repair physically damaged.
      Problem is I don't know if it is spilled sugary drink or hardened up old grease.

        Hi, there is no spillage whatsoever. Mixer is well serviced by me and there was just problem with faders which I spray with deoxIT and they are fine now, but I wanted to lube pots too and then I spray them too, and after I spray them, few of them are not moving as they used to. Some of them are ok, but some are moving like they need to be replaced. I already order 6 of them to replace. I mean mixer is 12 years old, not all pots are in daily use but some are, those that are not in use are making problems, and I tend to move them weekly just in case...maybe they just need some lubricating but not by spray with some grease. I have PTFE grease, but I would need to desolder them If I get you correctly ?


        Btw
        Pot for headphone is not closing the channel good on 0 I can still hear music like it's on 1, but only on one channel. I tried to clean that pot, but still same, any suggestion for that ?

          These are super cheap components, it's not worth your time to mess about with them. For reliability just replace them with better quality same value pots that fit... 🙂

              Value & taper should be written on the pot? .... if you tell me what they are I'll have a look...

                Hi, there is nothing on the pot no value or anything, sides are empty too. It must be some garbage pot.

                  You need to remove it... the value is usually stamped on bottom... 👍

                    I dissasemble one pot. before, it was replaced in warranty back in the days. It was same pot as the one in the picture above. But that new one that was soldered don't have any marks on it, maybe under but I didn't remove it from board so I can't say.

                    Here are picture of that one, it has some numbers on metal but when I google I can't find anything.

                    But I would like to replace all of them on mixer with better quality ones. They are not the same, some have center, some don't.

                      Here you go.. B503 is the important part of the number + 6 pins.... https://uk.rs-online.com/web/p/poten...B&gclsrc=aw.ds

                        Thanks. But dimension of the plastic handle is not correct. But now I know what to search for so I'll find right one. So that 50 in part number is marking ohms if I'm correct ?

                        I couldn't find this two AC103w and B503w pot. Can you help with this one ?

                        Bourns is good brand ? Someone told me to look for alps potentionmeters but I am not into pots so I don't know if that brand is any good.

                          In what way is the "shaft" wrong? Is it wrong type or too long (just cut to length)?

                          To decode the number :

                          The letter is the taper: B = Linear

                          The number is the value: 503 = 50 followed by 3x zeros =50000

                          The number of pins: 6 = dual gang or dual channel

                          So you are looking for a "Linear 50k dual gang pot"

                          The shaft = splined or D shape & either order correct length or cut to size.

                          Bourns are one of the best common pots, Alps are good too as are Alpha (Taiwan)... NOT the super cheap alpha copies from China.

                          There used to be good supplier in the UK who was familiar with all the different Behringer pots, I can't remember his name but I will post if it comes back to me.... 👍

                            Tnx for explanation.

                            That plastic thing where cap is going in is shorter on your link then mine. I think mine is 23mm not sure now, I will need to measure.

                              The plastic thing is called the "shaft", my link was just an example ... most pots are available in long and short shaft versions.

                              This guy that I couldn't remember earlier was a wealth of knowledge about replacement pots for behringer if you can't find them locally, maybe good for a deal if you want multiple pots: https://www.theaudioguyuk.com/produc...ntre-click/106

                              If it's Panasonic pots he's selling then they are pretty good ...

                                I am from Croatia, VAT from UK will cost me aaaalot, so it's not a good option, maybe ebay or somewhere from EU where I won't have to pay extra VAT.

                                  Try LCSC, TME or AliExpress.

                                    I tried aliexpress, but I could only find original ones, and those cheap ones I don't want on my mixer anymore. I want to put all high quality pots.

                                    Never heard of LCSC. But TME I was ordering from them, they are ok. But I don't understand what check12 was explaining to me in post about caps. I need someone to tell me this one you need and this one you need. On mixer I have few pots with different values PN. They are not all same.

                                      Then you need to list the serial numbers on each pot and also the number of pins... I am not telepathic... 😵💫

                                        Huh? You lost me. What caps? Take each style pot out you need, as you said you need a few different styles. Behringer stuff is all made in China. No point on really doing any upgrade if you ask me. These mixers aren't anything special at all. Just make sure you order a couple more than you need from Ali or whatever, so you got a spare. Make sure you have good solder and solder flux. Don't burn anything because of not using the stuff and Bob is your uncle. Behringer is German design, made with cheap China parts in China. Not worth spending the extra $$$ nor the effort. I fixed a few of these suckers.

                                          I'll do that thill the end of week. Need to disassemble the mixer again.

                                          Sorry my bad. I replaced all caps on PSU and with quality Nichicon and Rubycon low ESR caps, I mixed stuff. He was explaining to me about pots, that part I didn't understand about numbers and values. I would like to replace them all because it's cheaper than buying new mixer. I found some Yamaha with good caps and pots and faders inside, but I don't use my mixer that much, so It would be cheaper to me to just replace all junk stuff inside my behringer and continue to use it until it dies completely
