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

Filed under: Gear Reviews — Tags: , , , , , , , , , , , — mike.kobal @ 9:04 pm

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.

  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?

  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.
