The $29 XLR hack for the Panasonic Lumix GH4 (also works with Canon, Nikon, Sony)

this video was shot with the Sony A7r and the kit lens in 1080/24p

The Panasonic GH4 is currently the most powerful video tool you can get in a hybrid camera. With crazy high bit rates for HD shooters, 4k recording to internal cards pretty much destroys the competition. But we have one problem: No XLR input unless we spend another 1600 bucks for the interface brick. Check out the video for the $29.99 solution and get all the links to the products shown in the video after the break

To protect the cables and connecter I used part of a punctured road tube and home made rubber bands from punctured mountain bike tubes. You can also use velcro to attach the unit, I prefer the rubber bands in case I need to replace something on set.

First, you will need the Irig Pre, you can get it here at BH and here on ebay.

I got my splitter cable here on ebay from this USA seller.

I got my brackets here on ebay.

and this clamp here from BH.

  2. The splitter cable or “hack” is not needed to acheive stereo sound using the iRig & GH4. The iRig’s 3.5mm TRRS plug fits perfectly into 3.5mm TRRS mic input on the GH4.

  3. of course it fits perfectly BUT since it powers mic and headphones simultaneously, you have just plugged the mic AND headphones into the mic jack. I tried it and the result is an almost inaudible mic signal with the amplifier turned all the way up, the only way to get a proper mic signal is the splitter cable or you can modify the wiring on the irig pre directly. however, you don’t have to plug in the headphone jack from the splitter cable, you could plug them directly into the camera, it doesn’t make a difference.

  5. Interesting.

    Curious what you are listening to when you plug your headphones into the iRig: are you listening to the audio at the point of the rig, or is it receiving the signal at the from the headphone jack of the GH4? I.e., it would be the same signal as if monitoring from the GH4 directly…

    Thanks for the heads-up. Might be a nice backup to my JuicedLink.

  6. Hi Walter! It is receiving the audio signal from the camera. look at it as an extended audio cord, it work with the irig turned off and without battery and you hear exactly what you would hear if you had the headphones directly plugged into the camera.

  7. Alles klar, Mike. Ich danke!

    Comment by Walter — June 3, 2014 @ 5:25 pm

  8. would love to see a video on youtube demonstrating the noise and how it sounds.
    please post

  9. Hi Mike,

    Thanks for posting all this great information. Just a question about the splitter. The one you have looks like a TRS when GH4 uses TRRS. Does that not matter or am I wrong about that splitter?


    Comment by Jae — July 3, 2014 @ 12:14 pm

  10. HI Jae,
    the splitter’s female plug is TRRS and the male plugs are TRS. I too was under the impression I could just plug the irig pre in the GH4 directly, however, the volume drops significantly, appears to cause a short, but works as it should with this splitter cable.

  11. Thanks, Mike. One last question – what’s the battery life when supplying phantom power to a mic? Few hours or a full day?


    Comment by Jae — July 4, 2014 @ 11:13 pm

  12. Hi Jae, I haven’t done a battery drain test, I have used it for about 10 hours until now and the battery is fine. The manual states 15 hours for phantom powered mics. 40 hours for battery powered mics.
    It should get you through a 10 hour day without problems.

    Comment by mike.kobal — July 5, 2014 @ 1:31 pm

  13. Awesome. Thanks again!

    Comment by Jae — July 5, 2014 @ 9:49 pm

  14. This is fantastic! I can’t thank you enough!

  15. I have a Sony a77 and it doesn’t appear to have a headphone jack (only mic), will the Irig Pre still work and how would you connect it?

    Comment by Jeff G. — September 6, 2014 @ 10:50 pm

  16. yes, it will definitely work, you just won’t be able to monitor the audio /:

    Comment by mike.kobal — September 6, 2014 @ 10:56 pm

  17. Hi Mike,
    Thanks for the test and sharing. Trying to avoid one extra cable (the adaptor/splitter cable) I wonder if you have tried to connect the Irig Pre directly to the GH4 (I know you have done it) and then set in camera Mic Level to 0dB (not to -12db, which is the most common). Do you know if that provides an acceptable signal?
    Thank you

    Comment by Javier — September 15, 2014 @ 10:44 am

  18. Hi Javier, haha, yes I have done it, although the plug fits, for some reason it reduces volume to an unacceptable level. I know the extra cable is annoying, I just cut off the headphone cable right at the base since I am using the camera headphone jack.

    Comment by mike.kobal — September 15, 2014 @ 7:36 pm

  19. Mike’s been so helpful I thought I’d leave a note regarding my earlier question about battery life using phantom power. I recently shot a project where I left it on almost the whole day, 5 or 6 hours with about an hour or so of actual shooting and never had a problem with the battery. In fact, I often had about 60% left on a standard 9v duracell. That said, I would replace the battery after each day as I did notice some issues when I tried going the 2nd day on the same battery. Happy shooting.

  20. thanks for the update, Jae!

  21. Hi Mike

    I have a 5DmkII until I upgrade to gh4. Will this work with that body? Do I need the splitter since there’s no headphone jack on the canon?and does this mean I can’t preview audio through headphones?

    Comment by JH — December 27, 2014 @ 4:09 pm

  22. Yes you will need the splitter cable to get rid of the head phone contact points because the iPhone has mic/headphone input in one plug. If you just use a3.5mm stereo cable it causes a short resulting in very muted low vol sound, you can just cut off the headphone cable part on the splitter cable and only keep the mic plug. Unfortunately there is no way to monitor audio via headphones on cameras without a headphone jack

    Comment by mike.kobal — December 27, 2014 @ 6:48 pm

  23. HI…I own the GH4 as well…can’t seem to find the link to the splitter that you provided. Any other neat stuff about the GH4 that you can provide? Thanks. Wayne Krszwda

    Comment by Wayne Krszwda — January 11, 2015 @ 2:43 pm

  24. On eBay, search for “iPhone headset to PC 3.5mm adapter”

    Comment by mike.kobal — January 11, 2015 @ 4:55 pm

  25. Ok …got it Mike…thanks. I have to send my GH4 back to Panasonic for repair and I’m happy I came across your video. I don’t know if anyone knows this about the GH4, but I saw a video on the GH4 (YouTube) and the guy explained there’s an audio glitch in the GH4 when you plug a mic in the audio input i.e., the audio does not sync with the video – it lags behind by a few milliseconds. I was sceptical about this until I actually tried it myself – I down sampled 4K to 1080p and recorded to an external recorder while live streaming at the same time and sure enough, when I played back the file, the audio lagged behind by a few milliseconds. Although this glitch can be fixed in post by pulling back the separate audio track and matching it up with the video track, this can be a time consuming practice and for a camera like the GH4 and the price, we shouldn’t have to do this.

    So…a few weeks back I called Panasonic support here in Canada and told them about the audio out of sync issue. The lady on the phone was surprised about my issue and told me that Panasonic listens to its customers and that she would forward my concerns off to the powers to be. After talking with her, I said to myself: “yeah…right…I’m just another consumer and Panasonic is so big, my concern will probably be tossed in the waste paper basket.” But lo and behold, I called them back yesterday and they acknowledge the audio glitch and will repair my GH4. So Mike, please inform your followers of the audio out of sync glitch ( maybe not all GH4’s have the problem). As well, I thought Panasonic would not really listen to my concern but they did – and they took the correct action very quickly indeed. So…it we call Panasonic and ask for improvements to the GH4 ( bigger sensor…better low light capturing capacity) they will indeed listen. Thank You Mike – really appreciate it.

  26. HI Mike…what boom mic do you recommend for the GH4 to go along with the iRig?

    Comment by Wayne Krszwda — January 14, 2015 @ 7:52 am

  27. For best quality, you gotta break the bank and get the Sennheiser mkh 416
    The Rode ntg2, the best budget version

    Comment by mike.kobal — January 14, 2015 @ 12:13 pm

  28. hi Mike…my iRig Pre arrived yesterday so I’ll order the rest of the parts soon. I have the XLR to 3.5mm adapter….wouldn’t this be ok to use as well for the mic input on the GH4?

    Comment by Wayne Krszwda — January 16, 2015 @ 8:00 am

  29. Yes. I use it all the time.

    Comment by mike.kobal — January 16, 2015 @ 8:54 am

  30. I tried this with my 5d III, and it worked well, BUT when I dial down the manual setting on the camera, shoot, stop shooting and then start again, the level on the camera reverts to a much higher setting. I did not notice this the first few times and got some horrible sound. I wonder if others have had this problem, and how one can set the manual level and maintain it.

    Comment by Sean Kernan — January 30, 2015 @ 10:56 pm

  31. Check your settings, has nothing to do with the irig, the camera doesn’t know whats plugged in. You might have a high level set in memory and every time you turn it off and on it reverts to the orig stetting
