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!
