DDJ-1000 electrical noise in headphones

tl;dr - there is a loud electrical buzzing from the headphone jacks

Just got my DDJ-1000 (preordered on the day it was announced).

The center screen is great, and love the form factor however compared to all my other Pioneer gear there is a loud electrical buzzing when I connect my Macbook to the unit.

I've tried different USB cables, including the one that is included.  I've switched ports on my computer, even using another Macbook.  The electrical noise gets a lot more bearable when unplugging the USB,.   This does not happen on my DDJ-RZ, or my older DDJ-SX2 or DDJ-SR. Also, when pressing buttons such as "SLIP", I can hear a high pitch noise when the screens and lights on the unit flash to indicate SLIP mode.   

My second issue is that the sound feels 'harsher' and more overdriven than my other Pioneer gear.  Was there a change in the DAC? 

I have yet to use this unit out, but I'm concerned when hooking the outputs to a club PA this weekend that there will be electrical noise blasting out through the club's soundsystem.

 Could this be because Pioneer opted to use a external wall wart that has 2 prongs (not a grounded 3 prong design)? I'm in the USA and ordered from an authorized US retailer.  Thanks

Hi Nicos and all who have the headphones noise issue,

I already sent each of you a message to your email address used for this Forum thread on June 1. Please reply to that message if you want to comment about the issue you have.

Pulse might not know the engineers' and our QA team's response to your issues for some reason.

Please ignore his message and do not blame him.

Please reply to our email sent to each of you instead.

Thank you very much for your kind understanding and cooperation.

CRM, Pioneer DJ

It may even be that the power adapter is faulty; do you have another suitable replacement to try?

Unfortunately I don't have another wall wart other than the one that shipped with it.  I hooked them up to some home monitors (KRK Rockit) and the booth output appears to be clean.  

I have probably 30 or so 3 prong IEC cables (used with CDJs, DJMx, DDJRZ plus all my lights), however that won't help :)

I'm not sure if this is normal or a unique issue with me. Can anyone else take a listen to the headphones in a quiet studio setting and reply if there is this electrical noise.  Obviously in a live setting I wont hear it, but in a quiet studio it is a little annoying.  I'm trying to decide if I should contact pioneer tech support to get a replacement power source vs send the whole unit back to the retailer?

Hi, I bought a ddj-1000 yesterday and I have the same problem.... I can't mix with that noise it makes me crazy... I upgraded from a ddj-sr and i have no problem with that controller. My master output is also noise free... I hope you guys have a solution or do i need to ask a replacement with the retailer that i bought it from?

Interesting that i'm not the only one reporting this. I asked a few folks on reddit and they don't have the issue. It is certainly very distracting when mixing in a quiet environment. I'll contact my retailer to get it sent back. hopefully they have a replacement to send out.

@Pulse hopefully just a isolated incidents. Like I said I PM'd a bunch of folks on Reddit and no one else has the issue. Thanks for the help! Should I file a ticket to let the engineering team know?

I'll be opening an internal ticket, so you don't need to create one, but I'll need some answers to other questions first:

- Is the noise only in the headphones, or is it heard out of the master and/or booth outputs as well? If on the master, does the amount of noise change when you increase the channel gain and/or master volume?

- Does the noise occur when nothing is connected to the DDJ-1000 (besides headphones)?

- Do you hear the noise in the headphones when selecting individual channels, the master cue, or both?

- Have you tried using the unit at a different location (another electrical circuit in your home, a different venue), and did it change the noise?

- If the noise changes when connecting a computer, have you tried a different computer?

- Was the computer connected to the Computer A or Computer B port? Did it make a difference?

- Noise is only out of the two headphone jacks (1/4 and 1/8 inch). Tried multiple headphones too. I've only tested booth out, and it was clean. 

- It is present even with nothing connected.  Initially I thought it was louder with USB connected, but i think it's the same.

- No Noise when selecting channels.  Noise is present even with headphone volume down. The more lights that are on, the more noise there is. For example, when hitting SLIP multiple things flash on the unit, causing the 'flashing' sound on the headphone out

- I tried it on two different 110v circuits, noise persisted

- Doesn't matter on the input. Also, tried ferrite core USB cables, didn't make a difference. Also, noise was there with USB disconnected too.

 

Hope that helps

Very helpful - thanks! I'll pass this along and let you know what our team has to say, but it will be a couple of days due to the weekend.

While testing all the things you suggested i came with the same answers as dj chase gave. The 2 headphone jacks are the only things that give the noise all other outputs are noise free. And even if there is no laptop connected but just the controller turned on you can hear the noise, you can also hear the noise if all volume knobs are turned down.

Hey guys, can I ask another question about the sound?

Do you hear it at the same level regardless of any other functions or controls, and does it pretty much disappear if you're playing music with a channel around 0dB and the headphone level knob around 9 o'clock?

Hi Pulse

Sorry, forgot to reply to your last message.  I hear it any the same level regardless of other functions of controls. The buzzing starts right after powing up as soon as the progress bar in the Beat EFX reaches 100%. It doesn't matter if the channels are set to Line/USB A, USB B, faders up/down, master volume up/down, etc . Tried it with the USB cables disconnected and multple outlets.  I posted another thread to see if it is because of a newer (lower quality) DAC but you mentioned you dont have that info.  Hope this info helps

Today I got my new unit from my dealer, started it up and had the exact same noise again. Could this be a faulty batch? Because for the moment i see no other option then sending it back again? I also tested your last question but the noise is just static it doesn't get louder or quieter it is just Always there.

Got my unit over the weekend. I can hear a slight buzz from either headphone jack. 

Experiences matches all described tests aside from it being loud.

The product team is investigating the situation, but have recommended, for the time being, that you return the affected unit to your retailer for an exchange. I know stock may be limited and they may not have a replacement immediately available for you, but it's better to connect with them on this issue than the alternative of waiting to send it in for service / repair.

i have the same exact problem but its only noticeable in a dead quiet room. when i gig you cant hear it at all. the unit performed flawless. it might just be a manufacture thing. i had sent back 3 wegos for a similar hiss in the mic inout way back... all 3 had the same problem. You could never hear it when talking only if you were in a super quite room. Still annoying. AND especially annoying in a unit of this caliber. Could be a quality control issue.

Hello there,

I have the same problem with my DDJ 1000. Static electrical noise from both headphone-outputs, no matter if it's plugged in computer or not. I've tried different electrical circuits and -- problem stays.

Hope it could be fixed with new firmware (lot of hope :))?

Regards,

dj gobox

Just got back from the music store. The replacement unit had the same issue.
We then proceeded to check the showmodel, this one did not have the issue.

They guy from the store will send in a request to have the warehouse check on the available units and sent one that doesn't have the issue.
I'll post an update in a week or so.

@Ves > Thanks for that info -- I've been told the headphone output should be comparable to that of the DJM-750MK2 (likely the same headphone pre-amp circuit), which is relatively quiet (minor hiss, totally normal and acceptable). It's disappointing to hear there are some units exhibiting an abnormal noise, and we are working to investigate.

I'm having the same issue as described. Not loud, but a constant electronic noise in the 2 headphones jacks even when The ddj 1000 is just powered on no computer added.

Sorry @myjello, can't link without permission... and besides, this is the place to report your issues.

As directed to others, if you are having a problem with noise in your headphones, please return it to your retailer for an exchange (should they have one in stock).

The problem I have with returning the ddj 1000 for an exchange I will lose my 24 months no interest because they are not offering it anymore on pioneer products and if I return it they would have to refund and reorder under a 6 months no interest.

If you bought it on those terms, took it home, and it was completely dead, they would have to replace it for you as a defective unit. I would expect this is a similar situation; the unit has a fault, we're suggesting users return them to their dealers for an exchange, they shouldn't modify the terms of your sale (eg. financing) because of the unit. It's not a return / refund, it's an exchange.

Nope, they would have to treat it as a return because that one would have to go back to the store it came from in whatever state it came from and the new one would come from another store in another state. Only a few or scattered at guitar center around the us have them. Everyone else is on backorder last I checked.
