Kontrol Z2 Innofaders: The Inside Scoop

Just over a week and a half ago, Native Instruments announced the forthcoming Kontrol Z2 mixer, and many of our readers were excited to discover that it features three Innofaders, the crossfader and the line faders. But as the excitement grows over NI’s latest offering, so too have the questions surrounding the Innofaders inside the Kontrol Z2. Today we’ve got an exclusive interview with the Innofader’s designer, Elliot Marx to learn more about the story behind the advanced faders in the Traktor Kontrol Z2.

The Mini Innofader has been in existence for nearly a year, and we’ve been waiting patiently to start seeing controllers that make use of the slick performance of this size-conscious fader. The Kontrol Z2 Traktor mixer has all Mini Innofaders, taking the place of the normal Alpha faders that are found on the Kontrol S4, S2, and F1. To get the full background on how the Mini Innofader has changed while working with the Traktor team, we contacted the man behind the Innofader, Elliot Marx.

DJTT: How did the Native Instruments + Innofader relationship come about?

Elliot: I first contacted Aureliano Pisa, (Native Instruments Hardware Product Development Team Leader) in the run-up to NAMM 2012. Aureliano and I had previously worked together at Numark and I wanted to get feedback on the new Innofader product. At NAMM, I met with Aureliano and Jim Mazur (Head of Product Design for Traktor) and introduced them to the Mini Innofader. It was clear that they had done their research and had received a positive response from the Innofader users they spoke with. There were a few more meetings and even though things were moving forward, I still had no idea that the product in mind was the Kontrol Z2; I really thought the Mini Innofaders were for an S4 upgrade or another controller.

DJTT: How different are Kontrol Z2 faders compared to the Mini Innofader we reviewed in January?

Elliot: Native Instruments provided a tremendous amount of feedback which has done much to refine the unit DJ Techtools reviewed earlier this year (pictured to the right).

  • The Z2 crossfader is set loose for scratching with just enough tension to be stable.
  • The Z2’s 2-channel faders have a little more tension to ensure even mixing.
  • The fader stem is now grounded, ensuring it will continue to operate even if the DJ loses the fader cap.
  • The linear curve has been improved to ensure that the output is within +/-5% of perfectly linear.
  • The Z2 faders all have a cable hookup which could allow for calibration from the outside of the mixer. I’m not sure if this was implemented  and it’s possible that this function was removed as we already do very precise factory calibration (1/2mm cut-out, 1mm cut-in). There is still a button available on the Mini Innofader itself for DJs who really need it.

DJTT: Do the faders behave any differently when the Z2 is used as an analog mixer versus being used as a MIDI controller?

Elliot: The Innofader is slightly faster when the Z2 is being used as an analog mixer because the analog audio and crossfader signals don’t need to be routed through the computer. The delays are small – on the order of a few milliseconds at most – so the guys who would notice such a thing are hardcore scratchers.

DJTT: Are there plans for NI or Audio Innovate to offer replacement faders for the Z2 outside of the warranty period?

Elliot: I’m not sure of NI plans, but we’re definitely looking to offer replacement retail version mini Innofaders from Audio Innovate.

DJTT: What about offering Mini Innofaders with different tension settings for Z2 customers who want more or less tension in their faders?

Elliot: When we introduce the mini Innofader as a retail product, most likely we’ll offer 2 different tension settings as such.

DJTT: If someone was happy enough to toss their warranty out of the window, would there be any way to get a full size Innofader in the Z2? 

Elliot: We got together with the guys at DJ TechTools and have so far tested the Innofader Pro which will work with both the crossfader and the line faders on the Z2.  The Innofader Pro also uses the same mounting plates as the Z2’s Mini Innofaders an no new adapters are required as the Z2 uses the standard VCA hookup for the Innofader Pro.

DJTT: Kontrol S4/S2 customers- can they buy Mini Innofaders and make the upgrade?

Elliot: Currently we haven’t set up the Mini Innofader to do this. This would be something we’d consider in a retail model. I actually wired a mini Innofader in the S2 and found it didn’t work since the very basic VCA was not compatible with the circuit there. The S4 uses a unique mini connector to save space so that would be another thing required to make this work (Editor’s Note: Check our 2011 article for more information on how to upgrade your Kontrol S4 crossfader to the Innofader).

DJTT: Can we expect to see any other “Innofader Inside” products coming from NI in the future?

Elliot: I would say a lot depends on the success of the Z2. And if NI does have such plans, I wouldn’t know about specifics until pretty late in the game. As I said earlier, I thought that the Mini Innofaders were going into a MIDI controller up until I saw a Z2 prototype a month ago.

Today’s article was in response to quite a few questions and curiosity we got from users about the faders on the Kontrol Z2 – if you’ve got more that you want to know about the Z2 (or any DJ product!) feel free to let us know in the comments or on Twitter @DJTechTools

    Hallo, im looking for audio fader for my traktor s2. can anybody help me please?!?

  • calkutta


  • Patrick Dee

    Can I remove the plastic acryl mixer front plate in an easy way to change the faders ?

    • Elliot Marx

      I think the faceplate can be unscrewed for easy access. Any tips from the DJTechtools guys who did this?

      • Shane Dameron

        It’s magnetic pops off I took my z2 apart soon as I got it

  • pedro

    First they made the computer Software, then the soundcards! After that came the controllers and now the mixer ! What’s missing ? well, not much… but an iTraktor app would sound AWSOME!

  • SRGE

    anyone know why the lcd display on the z2 has space for 3 digits? Are they meant to display bpm or something other than loop length?

    • Alex Ground

      It has 3 spaces so 1/16 and 1/32 values can be displayed.

      • keef

        Also, it helps with some settings on the mixer that wouldn’t be reflected well on a 2 digit display. In one demo video the presenter changed the layout of traktor from 2 deck to 2 deck + 2 remix decks. When he did that the left display said “lay” (for layout) and the right had a number value that could be scrolled up or down.

    • Chris Jennings

      I didn’t notice that. The S4 has just two spaces and shows the dot for micro loops. I wonder of going to three hints at some other functionality to come to traktor?

  • Chris Jennings

    Excited about this
