[COMMON ISSUE] Sound distortion, internal buzzing

[magicalgin]

I didn’t really want to make another topic on this seeing as there are already plenty of topics on this issue but I’ve been left with no choice.

My mixer started experience the, apparently very common, buzzing problem that’s been happening to countless other X1800 mixers. Here’s a video of mine: https://www.youtube.com/watch?v=ilPGX_fvgBA

So I contacted Denon support the other day to get this resolved but I was just sent a PDF of the authorized service centers and denied warranty repair as it’s been past a year since I bought it. (I bought it in November 2018).

Now, under normal circumstances, that would be understandable. However, seeing as this is a common issue, as evidenced by the following topics:

Really bad buzzing/crackling sound when turned on

Hi guy’s, Have Sc5000 and X1800 and love them, the updates are coming thick and fast, and even the weak link Engine Prime is starting to improve…(more work need though lads ;-), and also a flipping android/ios app to ink to Engine for on the go…) Had mixer around 2 years never had any issues. The last month or so, bad buzzing sound starts staright away, if you give it a little “love tap” it seemed to sort it…for a while. Now getting line drops as well so guessing it is some internal connection…

Sound Interference X1800 Mixer No response from Denon DJ

Sent through a technical support enquiry out and a customer help on this. The South African Denon DJ / In Music agent representative has been in touch with my retailer and as far as I am aware they have taken the mixer in to test out, but no response from the website help support team for over a month? I have read many requests with no response from Denon DJ technical help staff . Are people waisting their time with after sales support? My products have been registered on the Deno…

x1800 sound is glitching heavily - any advice?

Awesome. Mine was returned from Denon in November last year and has just gone again this week, so I made it to 9 months. It’s been used about five times since then for gigs and been sitting still in my studio since lockdown started. Hence, I’m a little worried about sending it back to them for fixing again! I fear it’s just going to keep happening.

X1800 Buzzing Problem (again)

This is getting quite ridiculous. So many people are complaining about this issue on the forum and I’m beginning to worry about my choice of switching to Denon. This looks like it will be another post about a recurring issue that, so far, hasn’t been proven that it can stay fixed. I was playing a gig in front of 700(ish) people last year. The mixer (that was already showing signs of buzzing at home) crackled and cut out completely mid-set. The venue had another mixer on site and we plugged …

I can’t see why Denon can’t issue a recall, or, just fix the ones that do come in with this issue regardless of warranty?

For what it’s worth, the mixer has been sitting in my bedroom since I bought it, and has only been out to 1 gig so I doubt it’s due to how I’ve been using it.

it’s embarrassing on Denon’s part. They should solve a problem that they know is endemic in the 1800 prime

[j141]

Yup add me to this list of unhappy X1800 users with this issue

[michaelsum]

Has anyone UK based any idea of how much this costs to fix this with Denon? I put a post on the facebook group mid last year and someone sent me this video… the electric nois lik from a welding equipment stops - YouTube

I stopped using the mixer for a few months then plugged it back in to do the update few months back forgetting i had the issue and it worked for a few weeks then the crackling started again the last few days.

[j141]

I have finally got a response from their UK support so I will let you know when I find out.

[j141]

I have heard back from support, as my unit is out of warranty, it is a paid for fix starting from £25 if its quick fix and rising £ if its not.

I think im going to try the grounding fix in that youtube video first: Mixer making sounds and Audio Dropout - #49 by Reticuli

[magicalgin]

Honestly, I’m surprised they don’t already know what the root cause of the issue is. All our mixers have the exact same symptoms. Unless Denon/InMusic isn’t aware of this issue… which wouldn’t bode well for X1850 owners.

@magicalgin

Unless Denon/InMusic isn’t aware of this issue…

They have to know exactly what phase is, on too many X1800 units occured the same issues.

[j141]

I followed the video in the link I posted above from @Reticuli and its early days but so far it seems to have fixed my issue.

I soldered two extra wires between these three points show with the red line as the 3rd post seems a bit pointless:

I will update in a few weeks but hopefully this has fixed it, if your unit is in warranty and you are able you are best off sending it to Denon to fix but if its out of warranty or you are unable to send it this could help you. There is probably a better, less bush fix solution to this by beefing up the grounding at other points but if this works it should be fine.

MINE LITERALLY JUST STARTED DOING THE SAME THING? I was supposed to be doing a stream right now, smh

[michaelsum]

How’s yours holding up? I think i am going to try the same it’s not my main mixer i use Allen and Heath as well but thinking for the best part of £100 which it would cost with postage and Denon having a look etc i might as well have a go myself!

[j141]

My issue has now changed from the mixer physically buzzing when powered up cold to just getting distortion on the output for the first 5 mins or so then once it has warmed up its fine, ver odd.

Im going to send it to Denon its £25 for the first 15 or 30 mins (I cant remember which) and return shipping.

& me 2 This issue has been constant for me since purchasing it and its getting rediculous I have to bash the thing sometimes to get it to stop! Not like its covered under warranty anymore anyway so I guess ill be doing some surgery on her then I dont expect Im going to leave in a sponge or something lol

[SlayForMoney]

@Nubium

Hi. did you manage to fix this issue? ive got the same problem

There is literally a video on how to solve the problem 4 post before yours, do you not read the entire topic before posting?

[Nubium]

Yes I did, something problems come back and I was checking to see if it had still worked after some time.

And I wasn’t asking you.

[SlayForMoney]

@Nubium

And I wasn’t asking you.

Then send a private message.

This is a user forum, otherwise expect a reply from every smartass like me. Get used to it.

[Nubium]

Fair enough , my post needs to be at least 12 characters so I had to type more.

[michaelsum]

Hi J141 did you ever send your X18 back to Denon. I’ve not used mine this year but thinking with the updates i might get it back out but i’ve not because of the crackling issue… I’ve not tried the video fix either… Cheers

[j141]

Yeah I sent it back and they fixed it up, make sure they do you a deal on the repair bill as its a known fault.
