Experiencing latency and audio popping issues when I connect my NS7II Display to my Mac computer

I was super excited that Numark came out with screen to upgrade the NS7ii to a NS7iii. I might be the first to have gotten one. I stalked every store online until it came in stock. It showed up at my front door and I immediately slapped it on the controller and away we go.

Well..not quite. There are MAJOR latency issues that cause popping, static, and Serato mayhem like i've never seen before. My wonderful NS7ii turned into an unusable piece of trash. I've tried every bit of troubleshooting I could find on the internet to remedy the issue. Spent much time with both Serato & Numark customer support, replaced all my USB cables for new ones, even formatted my MacBook Pro and put a fresh install of Yosemite & Serato on it. No dice. Popping, static and slowness shows up in my set about 2min-5min everytime and I need to restart everything....rendering my set and equipment useless.

I commend the effort Numark but please test your products before you release them. This is a top of the line controller...a $1500 piece of equipment. There is no reason why a clean installed OS X Late 2013 MacBook Pro should have a single issue running your new hardware.

  • I’m beyond disappointed
    This still does not work on my iMac (2013). Works OK with my 2012 Macbook, but I'm looking to retire that thing. When is the Sierra support coming? This device hasn't worked with my iMac in over a year. Pathetic. I have literally tried everything to stop it from making pops and hisses in 20 seconds since the first El Capitan update was released alongside the NS7III. The screens have basically crippled this things usefulness. I never DJ anymore. This thing is a mixer for my PC more than anything. Sad!

  • I'm posting here again despite this getting moved? Anyone actually fixed on an iMac using 10.11.6 OSx and newest drivers, Serato (1.9.3) etc? Still completely janky for me, but does work on my Macbook running 10.11.5 and 1.9.3. Anyone else from the original issue?

  • Hey K-Ryp,

    I've been using my NS7ii with the Numark Display with my mid-2015 MacBook Pro for just over a year. I read just enough of your thread to be reminded of the issues that I experienced when adding the display - severe latency, unresponsiveness, crashes etc.- basically the system was unusable.

    I finally found a mention on Numark's site of an incompatibility issue with very specific MacBook Pros. As luck would have it my laptop was on the short list of computers with this known issues. I wish Numark had communicated this more clearly so I would have known to steer clear of this particular model laptop.

    The workaround is to use a thunderbolt to USB adapter to connect the Numark equipment. Once I bought the ~$90 device everything worked great. I still have occasional data connectivity issues, but typically everything works well.

    Your iMac isn't on the list of incompatible hardware, but it's possible that you are dealing with a similar issue. Have you tried connecting with something other than USB? I'm not familiar with the types of ports your iMac has, but it might be worth a shot if you haven't already been down this path.

  • I can't find a fix for this issue either. I have a Mac model 2014 and using a Numark NS7, but I had to wipe my computer twice because there is no serato support for macOS Sierra and the beta software for El Capitain doesn't seem to work either. I downgraded to OS X Yosemite and I am still experiencing audio issues: popping, crackling and static noises. I went to best buy to purchase another 3.0 usb port adapter...the Thunderbolt doesn't have the extra ports I need. I'm not going to pay $160 for additional ports. I have read through all of the troubleshooting resources.....I just don't know what else to do. I get about 30-45 min. max before it starts to crackle and pop again, if it doesn't do it off back after a reset.

    Are you saying that I HAVE to purchase the Thunderbolt USB adapter in order for this whole issue to go away?

    I hope it is not my unmark product. I bought it preowned last year. Immediately started having the audio issues.

    Any other advice or recommendations?

  • Hi Theron-

    Sorry to hear about your issues. I should call out that I don't work for Numark and don't claim to be an expert on any of their products. That being said, I have a strong technical background, especially when it comes to professional audio gear, so take whatever information I give with a grain of salt.

    Your symptoms sound very similar to what I experienced prior to finding out that with my specific macbook pro hardware version Apple has acknowledged an issue passing audio through USB. I read about this on Numark's website somewhere- I wish they would have communicated the issue in big bold letters on the NS7ii home page so I would have bought a different laptop.

    The workaround is to use a thunderbolt to USB adapter. I think I paid less than $100 for mine on Amazon. It sucks having to deal with one more dongle, but with this in place everything works like it should.

    Something to note: I believe that the root issue is related to the inability to pass bandwidth required for the audio and high resolution platters. Numark doesn't include this in their documentation anywhere, but after investigating on my own I'm fairly certain that both the ns7ii and numark display use USB2- which requires USB2 compliant cables to get the full bandwidth. These cables and connectors look like The regular "slow" USB1 types, but they are nit the same. Check to confirm that the USB cable(s) are USB2 or better, and keep the distances shirt as possible. Take any hubs other USB devices out of the equation. I hope this helps.

  • NS7III
    MacBook Pro Late 2012:

    Basically what I did was call and they set me up for a repair. After I didn't get any word on my NS7III for 3 weeks I called to see what was up. My product was sent back to inMusic instead of the repair facility in New Jersey by mistake so they marked it lost/stolen and sent me a brand new NS7III. The new NS7III worked perfectly for about a week and all of a sudden started the pop/skip/latency deal so I quickly restarted Serato. It's been working fine ever since. But the fact that a brand new one had the same issue but doesn't happen as frequently as the old one did was weird. I've played for 2 hours straight no issues so far. I was thinking about upgrading my MacBook to a later model but seeing the same issue happens with the 2014 isn't so reassuring. I'm just hoping the issue doesn't come back up later down the road especially when in the middle of a gig. Oh, so as far as the old NS7III, it did eventually find it's way to the repair center and they couldn't duplicate the problem. That's as far as I got with that one. Before sending it off I tried the Thunderbolt dongle as well but still didn't fix the problem. Even tried using the NS7III without the screens attached. I can't think of anything I didn't try actually.

    Good Luck, yall!

    I am supposed to use this controller as a working tool because animation is my main activity and at the end ... I bought a product 1100 euros so that it stays at home because despite that I have 2 Macbook Mid 2012 "1 model Macbook Pro 9.1 and 1 model Macbook Pro 9.2" , The problems are present and identical.

    I have installed the latest Firmwareupdates and the drivers in the NS7-Display and NS7-II, that was the first thing I did.
    I have OSX 11.6 and did not upgrade to Sierra, because I use the NS7-II heavily in Clubs and gigs, I rely on it.
    It also makes no difference on what USB-Ports the Display or the NS7-II is connected.
    The Macbook-Air has two ports. left and right.
    I can connect
    NS7-II left, Display right -> after 10-20 Minutes -> crackled Audio-Output
    NS7-II right, Display left -> after 10-20 Minutes -> crackled Audio-Output
    Display left, NS7-II on the Display USB-Out -> after 10-20 Minutes -> crackled Audio-Output
    Display right -> Ns7-II on the Dislplay USB Out -> after 10-20 Minutes -> crackled Audio-Output
    It makes no difference what buffer size is selected -> after 10-20 Minutes -> crackled Audio-Output
    When I have connected only the NS7-II, Serato runs wonderfully the whole night long.
    We have tested this on a different NS7-II, different NS7 Display and different MAC-Model, too.
    ___________________________________________________________________
    Also, I have another Setup. I have a Pioneer DJM-850K (Serato Hardware integrated)
    When I play with the DJM and 1210s – and have the Numark NS7 Display connected on the same MAC-Computer, everything runs perfect.
    So this Error is only in combination of the NS7-II with the NS-Display.
    You can easily reproduce it.
    Just connect a NS7-II on a MAC and the Display, load a Mix and let it play.
    After 10-20 Minutes you will have a crackled Output. You can only fix it by power the NS7-II off and on again.
    For me as a Softwaredeveloper, too the both buffers of the Drivers have different lengths so after a while they run out of sync. Even when you go in to Serato Setup and increase the latency, Problem goes away for a few minutes. but if you set latency back everything is more worse. For me this sounds definitely like a Numark-Driver Problem - not a USB-Port-Problem. The Display runs with Hardware from another Manufactorer, that proves that.
    Thank you!

    Hello,

    Big blow from Algam France, following all the problems I encounter with my NS7II, the product is still waiting for removal for a repair or for a dispatch of spare part, to the authorized technical service Audio Maintenance, the product has Was deposited on January 25, 2017 and despite different exchange of mail, we are still in training of what will be agreed !!! Result the product to 1200 euros will have served decoration in my room and now it does the same in an approved maintenance center !!! But what serious ... CHAMPION OF THE WORLD !!! I bought the Numark controller for professional use and not for a typical use dj lambda. My siret number is 48966008400034, company Cysmix Sono. Either they make a quick repair and / or exchange and if it is not possible to make a full refund of the device. The time of all this imobilization, I lose enormously on the duration of the guarantee of the product without counting or it can not be used because of the problems encountered, it is a shame!

    Hi all,
    I ordered the Kanex-Adapter and I can now confirm it is working at last with my Makbook Air. Connected the Display to the Adapter and the NS7-II to the Display in Chain. Runs fine until now. Hope this helps!

  • Hello, helmut0! I do not know if the answer you give me concerns me ??? If this is the case and indeed the Kanex solves all the problems encountered with my NS7II ... I will be ready to buy it!
    • Hi Pat, I can't tell if that helps you, All I know is that on my MacBook Air it's working with the KANEX-Adapter. I'm not using the NS7-II for Video mixing or Karaoke. I'm a live DJ and use it in Clubs and at gigs, but there heavily.
      The NS7 must run the whole night without interruption. I don't know what Model you use but on my MAcbook PRO there are two "Displayports" and on my Macbook Air there is also a HDMI-Port as far as I know. And if all that Fails for Video - I would buy a Apple-TV then you can transmit the Video wireless from your Macbook. It's just Options. However my Issue is resolved with the Adapter and in this case it seems that the Hardwareproblem is on Apple side and has nothing todo with Numark. (I'm not working for Numark or Serato, just a User)
    • Thank's HelmutO !

      NS7II driver 3.20 and firmware 1.05.

      I use a First Macbook 15" mid 2012 (Model 9,1), processor i7 Quad Core 2.3GHz, Ram Crucial 16GB 1600mhz, ssd Samsung 830 Pro Series 256GB, a Oyaide usb Class "S" Serie D+, OS X 10.9.5 Mavericks, "The Buffersize in setup is 5ms". The Macbook has been formatted in june 2016 with a clean installation of the system. I do not know how to solve the problem .

      Second Macbook 13" it's mid 2012 (model 9,2), I7 2 Core 2.9ghz, ssd Samsung EVO 850 500go, Ram Crucial 16GB 1600mhz, a Oyaide usb Class "A" Serie D+, OsX Mavericks.

  • When you take a closer look at the product Kanex adapter ... we would say that the connection used is a minidisplay port and not thunderbolt, I really do not want to find myself blocked for video clip or karaoke ... if the Connection used is the minidisplay port! http://d2csswqf447ug7.cloudfront.net/...

    http://www.apple.com/fr/shop/product/...

    If I want to mix videos it is the most suitable solution ???
    • Hi Pat, (I'm not from Numark, just a DJ). While looking at your Apples Spec I can see you don't have two Mini-Displayports/thunderbolt Ports like mine.
      All I could say is that on my MAC the Problems with the NS7-Display are gone with the Kanex Adaptor. So for me it's a good solution. That 90 bucks are worth the effort. So with your Video-Solution - sorry I have no experience with that. But maybe one solution would be to use a USB to VGA or HDMI Adaptor. to connect your external Display to the MAC. Don't know if this would work. Or you could use an Apple-TV -> You can use that wireless as second Screen device.
      (And of course you can use that Apple-TV standalone when you don't use it for your gigs) In your case I would try to get a used on eBay for about 50 bucks and if it doesn't work - sell it afterwards or use it for Netflix at etc.
      Just ideas.
      I hope you find a solution that will work for you.
      Cheers, Helmut (Raymaster X)

    Hello,

    My ns7II is part of after-sales service because of the various problems encountered, the technical support has completely changed the inside of it, but the problems are always more or less present which will mean that the problems would come from the Macbook Pro and the more it is That it is present on my 2 Macbook Pro Mi 2012, model 9.1 and model 9.2 !!! The problem would not it come rather from the driver ??? I will have bought the Kanex adapter but nothing proves that it will work better and if that does not work I would have put 99 euros per window! What should I do ??? In my region a ns7II this reseller between 400 and 700 euros of opportunity because people can resell them my product is new since I used it 5 times because of the problems I had and now that the product has been I'll lose all my money! Find a solution quickly, please !!!

    Hello,

    You will find attached a link of the different bug that I meet with my NS7II in video, despite a passage of the product to the after-sales problems are still not solved, I still have 3 months of guarantee on a product that has been used Only 5 times, more bugs this also produce with the NS7II outside the flightcase

    If there is one thing I hate is silence! What should I do that is the solution ??? I have to put all my thoughts and critic on YOUTUBE with all the video that I realized concerning the problems encountered with my NS7II and especially on the fact of lack of seriousness on the part of the technical support of Numark which do not seem to d Have solution to propose! Putting 1100 euros into a product so that it only serves as decoration is outrageous, I want either an exchange or a total refund, for me this product was meant to be a working tool and not an entertainment product in a room !!! It is so much easier to say that the problem is related to the computers that we have in our possession ... ok, it would have been possible to encounter problems on a computer !!! But, meeting identical problems on 2 computers is a little big !!! Especially, that I have one that does not even have a year!

  • The slow start - I'm pretty sure your NS Needs to be adjusted. When you turn the start-Speed knob to the right and back - I think it starts normal.
    I would do a factory adjustment of all Faders and Knobs, that should help.

  • Thank you HelmutO, for your answer regarding the Kanex which apparently, you have allowed to solve the problems that you met. Except that my two Macbooks are already equipped with USB3, so I doubt the usefulness of the investment except if actually the power supplies of the ports are not enough to manage the information on the NS7II ... but I strongly doubt ! Regarding the problem of slow start of the trays, I have already tried to reset the NS7II controls except that after a few months or weeks the problem returns. The worst bugs I encounter are the audio distortion and the random leap in a title either advance in the track or it backs off. I have the NS7II with the flight case and Numark technical support said not to use the NS7II in a flight case, so why Numark wind flight case depending on the size of the controller with a computer support if it is necessary to use The controller off flight case ??? In doubt ... I tested the controller off flight case and unfortunately the problem was present after 2 hours of use. Also, most of the places where I perform my services, the rooms are air-conditioned or do not exceed 26 degrees, so to say it is a problem related to a high temperature ... I find it weird! Except if the default product is very poorly ventilated. Another person had the same problem and he spoke about it on the site Serato:

    https://serato.com/forum/discussion/1...

    Sorry for my english... i'm french !
    • Hi Pat, can't confirm that. I use the NS7 heavily in Clubs and Parties and e.g. at the Oktoberfest where sometimes the NS7-II is in use for about 16 hrs, and sometimes its hot because I play in the sun - so never ever had a problem with temperature. The NS7 isn't powered from USB-Bus as far as I know, so that could not be a problem. My Problems begun only when I attached the NS7-Display together with the NS7-II. Without the NS7-Display the NS7-II runs also directly connected to the MAC USB Port. And exactly that Problem is solved with the Kanex-Adaptor.
      Regarding the Slow-start. I'm an electronic engineer so I can understand, that the knobs and Faders of the NS7 are Analog and mechanical Parts. So e.g. sometimes the surfaces of knobs have oxid after a while. It's like in old times when a Fader or knob of an analog DJ-Mixer becomes elder, you could hear crackling in the Audio-signal. I think it's the same here - after a while maybe if you don't use that start time knob so often, it has contact problems, and when the contact is missing, it's like the knob is fully turned to the max -and that causes the slow start. That's just a technical explantation. So if you got that problem, just turn the knob a few times left right and that should be gone - or the knob should be replaced. (which means you need to completely disassemble the whole NS7-II - it's not very technican friendly, I've done that a few times. Personally I don't use the Flightcase anymore - it's to heavy and unhandy for me. I use a MAGMA Case - that's great if you are a mobile-DJ. I just grab my bag and off to the Club. However - I'm sure the Audiodisortion will be gone with the KANEX. Cheers, Helmut (Raymaster X)
    • Thank you very much for taking time to answer ;-)

      My NS7II dates from June 5th, 2015 and the problems began to appear at the end of October 2015 at this time ... it had been used only 3 times only, I use my Rane 62 with a pair of Technics SL1200MK5, the NS7II serves Only on places where there is not enough room for a vinyl set installation.

      Therefore, between the little use I had, I doubt that the rotary knobs "start time" and "stop time" is worn or even oxidized, moreover when the controller is not used. It is protected from dust and moisture thanks to its flight case which protects it.

      I've never encountered a bug with my Rane 62 or even the SL1 and SL3 that I owned while using beta versions of ScratchLive and Serato Dj with Pitch n time DJ and Serato Video and even with the NS6 I never had This kind of problem even using it in a flight case also for more than 2 years.

      I sold the NS6 ... because the touch vinyl, I missed a lot!
