Topic: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hello,
I posted yesterday about a faulty potmeter problem on my Konnekt 48, which has only started happening recently. Basically pot 1 is very quiet, and impossible to turn up. I bought the interface in January, 2nd hand, but have now registered it in my name (I guess the registration went through because the original owner didn't do it).

The service centre in the UK said I would need to have the original purchase receipt from the original owner in order for them to look into it. Also it would take 10 - 14 days for the job in total! Luckily the original owner was very helpful so I've contacted him and hopefully he'll be able to get the receipt to me.

I couldn't reply to the sticky post because it is now a closed topic, but I wanted to clarify the statement on there:


"We have decided that we will change all faulty potmeters under warranty, no matter when they were bought"


I thought this was pretty clear, but I quoted this to the service centre and he wasn't sure if that meant the unit still had to be under warranty in order to qualify?? I.e. does it mean "we will replace faulty potmeters BUT ONLY IF the unit is still under warranty"?? I'm not sure if my unit is still under warranty, until I find out when the original date of purchase is. Can anyone clarify if they are replacing any units/pots, or just the ones which are still under warranty? I'm surprised the service centre couldn't tell me more about this over the phone, given that they must have seen the problem before!!

Anyway the other thing I was told by the service guy was that the serial number is early, so he was doubtful if it would qualify as "the problem would have shown up very soon after the unit was sold". It just sounds like they're making excuses before I've even sent the unit in, because I know for a fact this problem was NOT there when I first got the unit, it's only started happening in the last few days. The problem I am having is that I am not getting any gain on pot 1, even though it sounds clean it is very quiet, and turning it from right down low to max hardly makes any difference. Can anybody also confirm if this would come under the faulty potmeter problem? It is clearly not right, although I'm not hearing any crackling or anything like that.

Any info would be greatly appreciated, otherwise I'm in the situation where I have to send it in for 10-14 days with no certainty how much I'm gonna have to pay to have this problem corrected. I'm starting to wish that I'd just paid a bit more and went for an Apogee Ensemble now, which is what I was originally planning to do. I'm hoping that TC Electronic can convince me this is not the case and I can in fact get this fixed without major headaches!

Hello

I suggest that you call Sales department at TC Electronic and explain your situation.  If they agree to help you even though your unit is out of warranty, they will send an e-mail to your local TC service centre, and then you will have to contact your local TC service centre and send a copy of your e-mail to the Sales representative with whom you were on the phone.  This might or might not work OK for you, but I had very good experience myself in solving exact same problem with my Konnekt 24D.  One of the input pots didn't give enough gain and my unit was also out of warranty, like yours, but TC have decided to help me for free.  As explained, I had to call TC Sales department in Denmark, and then they had to contact my local service centre and then the local service centre accepted my unit and fixed it free of charge.

Hope it helps,

Andrejs

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi locojohn, thanks for letting me know, I think I will call Denmark tomorrow and explain the situation. I hope I will receive the same level of service which you did! Otherwise it's really bad news for me, as I don't really have much budget left for these sort of repairs, especially when it's a known issue with a very basic function of this kind of interface.

In any case I will post back to let you know what happens.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Just an update to this topic, I'm currently using a workaround for the preamp not working, because I also have an apogee duet and I'm not doing projects which require lots of inputs at the moment. It's just very annoying and frustrating to have 2 main inputs on my main interface busted!

I've spoken to TC Electronic who were very helpful, but I'm still waiting for the original owner to find the receipt, which he thinks he still has but are in storage. It sounds like it should be covered through TC and the official repair centre if I can find the receipt. However it sounds like a complete PITA if I can't get hold of it. I'm glad I actually called TC in Denmark because they were very nice about it, however the official repair centre themselves (Panic Music in Cambridge) were very negative and dismissive when I spoke to them on the phone, coming up with multiple reasons why it "might" not be covered. They also said if I can't find the receipt it seemed I'd have to leave the unit with them for at least 2 weeks before they could even tell me how much the repair would be! Typical UK customer service... If I don't manage to get the receipt and TC can't step in and help me any further, I think I'll definitely take it to a repair centre that I know and trust in London instead rather than those guys, which should be cheaper anyway (or at the very least they'll be able to tell me how much it's actually going to cost without leaving my main recording interface in there for weeks!!).

I actually have an update to the problem, because yet another one of the potmeters has died! I think it might have been caused by a particular mic I was using. It's a Sanken CMS9 stereo mic (mainly used for field recording but also studio work). This is quite a high end mic, and I'm very surprised this could cause this sort of problem. However the reason I suspect this might have caused it is that I used the mic for another session a few weeks later, and because my input 1 was not working I plugged it into 3-4 instead. About 15 mins into the session input 3 started exhibiting exactly the same problem, and is now permanently broken! I have now stopped using that mic with any Konnekt interface, because I now think this is the cause.

After this happened I was worried that the mic may be damaged. However I tested it with my Apogee Duet and it was absolutely fine, 100% working and sounding great. Shortly afterwards I also tested it with a Zoom H4 handheld recorder, and it also worked perfectly and sounded great. The mic only requires standard 48v phantom power, so I'm confused as to why my Konnekt 48 seems to have such big problems with it, when the mic is obviously functioning properly. Specifically the Left input of the mic seems to very quickly break the input potmeters on the Konnekt 48. Given that the mic is working perfectly with other preamps/interfaces/recorders this is presumably a design flaw with the Konnekt 48? If anybody can shed any light on this (particularly anybody from TC Electronic) I'd be extremely grateful.

Hello and this is something I find entirely wrong.  The local TC service centre in Riga didn't even ask me for a receipt (as I explained that I bought my K24D online in a U.S. internet store)  They only wanted me to provide a serial number of the product and approximate date of purchase.  In general, they said if TC Electronic Denmark gives permission to repair the unit for free (which TC kindly did), I can bring it over to the service centre and they'll fix it for me (which they did).

I presume this is how the TC service centre should act in the UK as well. I think you may just go ahead and demand an explanation as to why would you need to show them a receipt of purchase if you have a faulty unit that needs to be serviced BY THE LOCAL SERVICE CENTRE according to the way repairs are done with TC products worldwide.  I think requiring a receipt seems like they just don't want to bother much with your problem, while in fact in the light of events it's their duty to help you, I think.  It should be no matter where you bought your unit, but since you live in the UK, naturally it's the local service centre that should assist you with your problem.

In my opinion it has nothing to do with your wonderful Sanken mic or phantom power -- you've just got the unit with faulty potentiometers on mic inputs.  They just need to be replaced.  It's a popular problem my friend, but I think you just need to ask your local service centre to do their job. :-)

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi Andrejs,
Thanks very much for your advice and encouragement, much appreciated. I think I will find out when and where the Konnekt was purchased by the original owner (he's having trouble finding the receipt, but I'm in touch by e-mail and he is trying to help so it will be easy to get this information). Then I will call TC Electronic again and explain the situation, mentioning that I know other customers have had a similar problem fixed without needing to produce the receipt. Like you say, it's only fair different customers should receive the same customer service!

Even if I do get the Konnekt fixed soon, I don't think I will actually risk plugging the Sanken mic into the Konnekt pres again, just in case! As you say, I should be able to do this with no problems, and it's clearly a design flaw with the Konnekt pres. However, given that I have an Apogee Duet as well that I can use in aggregate with the Konnekt I think I will always plug the Sanken mic into the Duet instead.

Thanks again.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hello,

I actually experienced similar problems in France, with pots 1-3 dying one by one (I am using several line-in but only one mic) when I used them. Took it back to the shop's technical support, who sent it straight to TC France.

I also noted that "Up until now our policy has been to exchange units when ever a unit has an issue. This means that there is no repair time for customers - it's a simple exchange." which was definitely not the case in France as the unit came back 4/5 weeks later, same unit, but then I don't really mind about the case, what I really needed was that unit quick.

Around 3 weeks later pot 1 died again. I actually kept the unit for some time as I desperately needed it to finish an album (it is my only interface, and I need the unit more than the mic input), and now that the album issue is sorted, I took the unit back to the shop over 3 weeks ago. (which will make at least 4 weeks as the transport between the shop & TC France is on every Wednesday).

2 weeks after deposit, the guy from the shop told me the unit was to be available during the day. Once there, suprise, the unit was not ready, and there was some babbling  about TC France making a fuss about repairing the unit, which was kind of shutdown when the shop's owner realized I was listening. Apparently there are other issues with the pots, which was why everything was taking so long.

Would you have any info on other pots issues? Mine having been through TC technical support, I can but suppose they were not changed with similar faulty pots. Is there another technical issue which can cause input pots to die ? or is TC France technical service neither up to speed with TC policy (change of units)  nor TC repair procedures (repairs lasting less than a month)?

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Is there a serial number range of SK48's that are effected by this issue?

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi Document 02,
Thanks for the info on your problem, which sounds exactly the same as mine. I still haven't contacted TC Electronic again, because I'm still waiting for the details from the guy who sold me the interface. I don't think he will find the invoice but (as Andrejs said in his post) all I should need is the rough date of purchase and the name of the store it was purchased from in order to have the unit repaired quickly (once I have this info I am going to call TC Electronic again).

However, whether the repair will be easy for me or not will depend on whether TC Electronic is willing to provide the same level of service to all customers. Which after reading your post appears NOT to be the case, as you have had a headache trying to get this sorted out in France. I really cannot do without my interface for 4 weeks, which is also what the official repair centre in the UK is telling me I will have to do! This also goes against what TC have said on here about "no repair time for customers", clearly in practice this is NOT the case for all customers! This really doesn't seem fair at all, when it's no fault of the customer who has bought what is meant to be a high end interface which is plagued by a very basic problem with one of the most basic functions.

I really want somebody from TC Electronic to read and comment on this, as there appears to be some confusion here. PLEASE could somebody from TC be brave enough to reply this topic and clear up the confusion about what sort of service Konnekt owners should expect to receive when this problem occurs?? I noticed the original "sticky" topic on this forum has been closed, as if this is a non-issue and has all been sorted out. However this is clearly not the case!!

I have to say to Document 02, if I end up receiving the same poor service that you described then I will be extremely disappointed, and I will certainly be posting about my experiences on the other audio forums. I hope it will not come to this, but I will keep you updated as to what happens in my case.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Reading other forums, the problem seems far from rare (whether not working, or getting different levels on the preamps), but does not seem to happen more than once, usually.

However our experience & TC "policies" seem to point to discrepancies between what is stated & what really happens. I stopped recommending the interface until I hear credible news from TC and/or my reseller.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Thanks for your input, yes I'm still hoping that somebody from TC Electronic will comment on this thread to clarify what the policy is!

In theory what they are saying is they will repair this problem quickly and with a minimum of fuss, which would be great. But in practice the level of service received seems to vary a lot from customer to customer, which is obviously making the repair process quite frustrating for some.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

5th week without my SK48. So much for the "quick" part.
I4d really like to have some clarification on "TC policy". Like should I expect a new model after this, or is TC policy something that has changed since?

Yes exactly! If TC Policy has changed please could somebody from TC Electronic comment on this? TC are being very quiet on this, nobody seems willing to comment at the moment! Otherwise it is quite a sneaky move to close the other sticky thread on this problem as if it's all fine when customers seem to be routinely receiving this poor level of service!

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Still absolute silence from TC on this! They obviously really don't want to talk about it...

I hat to have to say this, but I'm starting to wish I bought an Apogee Ensemble instead of this piece of junk.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Had some news...

So... my unit has been at the TC repair shop for 5 weeks. Apparently they started working on it 2 weeks ago. There are also 3 other units at the shop with the similar input issues.

Now, it might seem weird to hear that 2 weeks were not enough to diagnose or repair the problem (let alone the missing 3 weeks), but funny enough current repair shop position is that all 3 units work.

I can understand they would not be able to repeat the problem on one unit, but the similar pot issue on 3 units...

For info I have 2 live sets coming, including my album release party in 2 weeks and I am seriously pissed off as I can't even properly prepare all my files since I don't have the fabrik R plugin available.

And the fact that there is no answer here is also starting to give me a very bad feeling about this whole company aftersales & quick repair policies.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

So the reseller just confirmed. 3 faulty SK48 were sent back at the seme time for servicing. None of them were repaired, they will all be sent back as "working".  (info was confirmed on monday, they will actually be sent back last wednesday, just to add to the quality of service.)

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

What?! So they're even pretending there's nothing actually wrong with the potmeters now?! This is insane...

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

I am sick of this. I reported the whole thing to TC support center. I'll see what their answer is.

Meanwhile a friend just lent me a Edirol to work with, and I went back to the sites where I had reviewed this unit to update the reviews.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi

Sorry to learn of your problems.  It may surprise you to know that I have had five.......yes FIVE units since my initial purchase in April 2008.  The previous four all had pot problems like yours.

The one I have at the moment also has discrepancies re input gain  - in other words some are louder than others - I guess I should have stuck with my first one and had all 4 changed as I do believe the ones that TC fit are not up to the constant plugging/unplugging.

So my advice to you is to have all four pots changed.

It's such a shame as the device itself is really excellent - let down by poor hardware.

I wish you well with your problem.  There is no way that your mic could have broken the unit.  My experience of Panic is the same as yours so you are wise to go elsewhere.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi Les,
Thanks for your reply, I'm not sure how Document02 is getting on, but I'm now at the point where I have got hold of the invoice from the previous owner and I'm about to try and get the repair done. It's freaking me out somewhat that these interfaces seem to be so delicate, as I may need to do some freelance work from my studio soon using the Konnekt (usually I do contract work outside but I'm trying to make sure my set up is reliable enough to use on a daily basis as well, which is looking increasingly unlikely with the Konnekt 48!). I wish I could sell the Konnekt 48 and get an Apogee Esemble (obviously spending a bit more cash...), but with the pots not working clearly that's not an option! The whole thing is kind of depressing, having invested in two Konnekt 48's earlier on this year with no idea these kind of problems were common. I did a fair bit of research on the net before I bought it, but you really have to dig around to find any info at all on this pot problem, so it did not come up!

My main question to you is about replacing the pots, yes it does sound like a good option to replace all 4. However, I contacted another service centre who are usually great and very quick, but they said they wouldn't be able to do the repair because TC Electronic refuse to sell parts to anybody apart from the official service centre. Are you saying they can be replaced with other pots? If so I may go back to the other place and see if they will do that. If this is possible then presumably that would completely void any warranty though TC though? Thanks for your advice.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

After calling them today I decided to book the unit in to the official service centre after all, because I only have until early December until the warranty runs out... Also they assured me the problem would definitely not recur once the pots have been replaced, they seemed sure of this. I'm not sure if I actually believe that, but will give them the benefit of the doubt and cross my fingers, touch wood, etc. etc.! The good thing is they did say they would definitely be replacing all four of the pots, rather than just the ones which are broken.

The repair time is 14 to 21 working days (so between 3 and 4 weeks), but when I queried this they said it was NOT a guarantee, just a guideline! They knew nothing of TC Electronic claiming to fix this problem or replace units quickly. In fact he asked me where I got the information from, and when I said it was a TC official on the TC Electronic forum this apparently means nothing if it's not on the TC Electronic website itself (even if posted by a Moderator who obviously works for TC). Go figure...

So I will send the unit in tomorrow or early next week and post back with the results!

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi

Sounds like you've done the sensible thing.  I would very interested to know how you get on.  It's crazy isn't it.  I've owned loads of cheaper interfaces that have never ever given me any problems like this.  You spend a £1000 on the "Rolls Royce" only to find you've got a Robin Reliant!!

Lots of luck

btw I also use a Mackie Satellite - absolutely brilliant, no software needed, built like a tank and works every time.  Cost?.........£135!!  Daft!

hi marzi....

you have done the rite thing im doing the same myself...

sent my unit off a week ago as it is better to get your pots replaced rather than have a new unit that may have the same problem. I Had a chat with the service centre on the phone and they said that all 4 pots will be replaced even if just one or two are broken providing they are the first ones which people are having trouble with....if not they will replace the faulty ones.
i read on the forum that they will be using a new type of pot from ALPS which is a very respected supplier of encoders and potmeters amongst other things.
Most of the top name companys use products from ALPS... especially companys that make synths...a couple of years ago i replaced a couple of encoders on my waldorf XT and havent had a problem since and they are still going strong.

i have faith in TC, i have used there products for a good few years and have never had a problem...i guess a few of us are just abit unlucky to have a TC unit with these kind of problems.

Good thing thing is TC have aknowleged the problem and been open about it, its not like they have kept us in the dark....

just hang in there buddy in a week or 2 you will have your unit back as good as new and you can be confident that the same problem shouldnt arise.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

TC support center replied asking which repair shop was concerned, I answered but got no answer after that. The unit came back to the shop one or two days later, no repair done. I retested it at the shop before taking it home, & weirdly the faulty pot works.

To be honest I am very suprised as I waited until the issue was happening a lot, to be sure it would be tested faulty. My guess is that they opened it or so, and some inner faulty connection came back in place.

I'll wait a bit and see if the problem comes back. If yes, I won't go through the reseller but take it myself to the agreed repair center with a TC support number/answer beforehand, as they seem more reactive than the local repair shops.

Nothing helped in explaining the 6 weeks total non-repair time though. (and it did f*** up my album release party, as I did not have enough time left to prepare it properly).

@jazkat: I already had my 4 pots replaced (3 out of 4 did not work), so there is no guarantee the problem is not a recurring one. You are also very optimistic concerning the repair times, as the first round lasted 4 or 5 weeks, and the second round 6 weeks.

Re: Input Potmeter Problem with Konnekt 48 - Please Help!!!

Hi Document  02... Sorry to hear you are still having problems, that's so weird that the problem came back even though the pots were replaced! Maybe they said they replaced them, but tested the unit and found the pots to be working, then didn't actually replace them after all?? (Or perhaps they did but they were not the ALPS pots which Jazkat mentioned...)

I'm saying that because I am planning to send my unit back on Monday, but did a test recording last night to see what would happen, and in fact one of the pots which was broken DID work initially. However after about 30 mins of recording it broke again, and would not go back to normal. I was surprised that it worked at all, but I wasn't very surprised when the problem came back. That makes me slightly scared that the repair centre will test it and find it to be working initially, and send it straight back to me without doing anything! So when I send it back I will make sure to mention in the covering letter that this problem seems to go away when the interface is not used for a while, but always comes back in the middle of recording.

Whatever happens I will definitely be posting back here with the outcome. I will also request in writing (e-mail) from the repair centre that they will definitely be replacing all 4 pots, specifically with the ALPS pots which Jazcat mentioned.
