  • Hello,

    Thanks for posting. Sorry to hear about your troubles.

    Very important, make sure you always have the latest audio drivers installed for your computer along with Serato DJ. Log onto the product page to download and install the latest audio drivers for your operating system - www.numark.com/products/ns7ii. Log onto Serato's website for their software - www.serato.com/dj/downloads.

    I've been using my NS7II for over a year now and I DJ every single weekend. I've never experienced my master sound from cutting out. One time one of my channels did but that was due to the venue's terrible ground and outlet. I ended up plugging it into another outlet and surge protector to rectify my symptoms. Make sure you're doing and trying the same thing too.

    At one of my gigs that I do a few times a month, I spin mainly electro house music at the club and it's pumping pretty loud from for over 4 hours. I make sure it's plugged into a surge protector, my master volume is no higher than 12 to 2 o'clock, my channels gains are at 12 o'clock and the sound is perfect. Not once did I lose master audio. Now, for this amount of time, your NS7II is going to get hot. Really hot inside the unit. Make sure your NS7II is sitting a wide, open, vented area while your DJing to allow proper airflow.

    Lets make sure your computer is optimized too.

    I always recommend to connect your NS7II to the USB port closest to your power supply. That port will always draw the most power to your DJ controller. Try a different USB cable. Sometimes a simple thing like a USB cable can play the middle man with these symptoms.

    It's also very important that prior to DJing, any new songs you added to your song database gets fully analyzed in Serato DJ to ensure smooth and functional playback. If you have a corrupt file in your Serato DJ database, this could cause these symptoms. I recommend deleting any file with a lightning bolt next to it from your Serato database. This means deleting not only from your crate but from your ALL location in Serato DJ. Fore more information on corrupt files in Serato DJ, check out the links below:

  • I dj 5 days a week usually. everything usually works right, but the audio cutting out bothers me a lot because i can't pinpoint it. latest drivers are ALWAYS installed religiously. all songs are also analyzed. i never leave corrupt files in my library. My usb cables are the expensive ones from dj tech tools, butr i can try switching that out. the usb port on my macbook closest to the power supply is the one shared with the built in web cam... the other port isnt shared with anything. do you still recommend using the closest to the power supply? i have done all of the mac optimizations in your guide previously

  • all of my gain knobs stay at 12:00, my main level knob stays between 10, or 11:00, my levels are in the green and occasionally venture into yellow. i adjust my levels with the upfaders. i believe the audio quitting seems to happen when loading a song onto a stopped deck, but everything (besides the sound) continues as normal. i put on my headphones when this happens and loud hissing is all i hear until i power cycle the ns7ii
    • Make sure you enable "Instant Start" before you start your set. Simply turn your Start & Stop time knobs clockwise then counter clockwise prior to your set. Here's some more helpful info to help yourself out.

      1. Connect and power on the NS7II
      2. Open Serato DJ
      3. On each deck, fully turn, clock and counter clock wise, the Start and Stop Time knobs prior to DJing. This will ensure that the NS7II is properly communicating with Serato DJ.
      4. As a good practice , we also recommend moving the Pitch Sliders, Crossfader and Channel Sliders up and down prior to DJing your set. Again, this will ensure that the NS7II is properly communicating with Serato DJ.
