ModMic 4.0(3.5mm->6.3mm) does not work

I'm not getting any signal from my ModMic 4.0 connected with a 3.5mm->6.3mm TRS/TS adapter(neither seems to work) into my M-Track MK2's 6.3mm connections but it does not seem to get any signal from the Microphone. Any idea how to fix it or should this even work?

This is the connector for the mic and the two adapters I've tried with the 6.3mm(1/4") inputs on the M-Track Mk2


I would love to get this to work, would be sad to have to return the M-track Mk2, the build quality and the design are both awesome and it already feels at home on my desk.

    Hi Richard,

    Thanks for posting!

    As far as I can tell this mic may not work as it does seem to be mostly intended for a direct to PC/gaming system input. I was unable to find any specific info on this mic that might be helpful (dynamic, condenser, does it require any power, etc.) but I did find this article:

    https://modmic.uservoice.com/knowledg...

    They suggest specifically to use an 1/8" to XLR adapter to attach to a mixer. When using a TS or TRS connector with the M-Track you will only have Line or Instrument level input options. Technically this will not amplify a microphone signal correctly and could be playing a part in your problem.

    The article also mentions something about 12v (and the company also sells USB adapters) which tells me that the mic may require some sort of power. The M-Track will send 48v by enabling the phantom power setting but 1) this will only be sent when using the XLR jack (not 1/4") and 2) may overpower the mic and damage it. +48v phantom power is the norm for virtually any audio interface for use with studio condenser mics.

    Unfortunately, I'd have to say that it looks like this mic is not going to work with the M-Track MKII but I don't think that any audio interface would work here unless you could change the phantom power voltage. If all you want to do is use that mic for something, than you may be better off with just on of their USB adapters. But I'd certainly recommend keeping the M-track if you're planning on doing any music or studio recording!

    Let me know if you have any questions about this and I'll be happy to look into this further!

  • Thank you very much for your reply, Corey. I will try with an XLR-adapter and make sure that the +48V is turned off. The reason I was given the M-track MK2 was that I've only had issues with those small USB dongle sound cards so I wanted to step up to something better sounding and higher quality.

    Hopefully the XLR adapter will work, would be a shame to return such a beautiful and nice quality product like the M-track MK2.

  • It does not work, the 6.3mm ports does not feed any power, at least not enough, to the microphone so unfortunately a mic like the ModMic will not work with the M-audio Mtrack MKII.

  • I actually have Scarlett interface and it does not work as well. I guess there is no way how to use ModMic with an external audio interface. What a shame!

  • Hi, I have the same issue with a Motu M2 but with the help of this thread: https://linustechtips.com/main/topic/... I have discovered the Rode VXLR+ which will fix the issue of 0V phantom power out of a standard interface on TRS jacks. It will grab 48V phantom -> 3-5V phantom on a 3.5mm jack, which is what PCs provide.
