5D MarkIV - external microphone not working

[Ivos]

I have a surprising problem with my rather new 5D Mark IV. When I connect an external microphone, it does not work ... still recording on an internal one (be it Rode or now Sennheiser MKE 440). When I connect the same microphone to 70D , the microphone immediately works (stereo), when I disconnect it, switches to the internal one.

Is there any special setting in 5D MKIV to initiate the recording via external mic or there is simply something broken in my 5D ?

50 fps is NOT high speed. Everything under 60 (59.99) is considered as normal. HSR is 120fps.

So your mic should work at 50 no prob....

Ugh. So in that case, I don't know what went wrong, I used the same mic the next day without any issue (although I filmed at 25 fps just to be sure).

Not sure if that's your case - I had a similar issue with my 1dx2 a while ago. Couldn't fit the microphone jack all the way in, and as a result - no sound 🙂

I would suggest to experiment a little before "going live". You can probably insert your microphone and knock on it to make sure you're getting sound from it and not from the internal one. If you're shooting live - have your audio levels on the screen. If something goes wrong - you'll see them either not moving or low. It helps to avoid surprises.

Thanks - yeah I’ll definitely check it better next time - completely forgot about having audio levels on the screen too! Must have been the microphone jack as it worked the next day!

It seems sadly I have the very same problem - more specificly:

I have just got my new Sennheiser MKE 600 and Sennhesier KA 600 i adapter cable (XLR to mini-jack adapter). I have successfully used this combination to record voice-memos on my MacBook Pro and Ipad Prop using the mic's internall power supply. I have also successfully used the MKE 600 to record sound on my Zoom H6 (with its phantom power) using an ordinary XLR cable without any problems.

However, I am surprised that it doesn't work on my almost new Canon 5d Mark IV, which records sound through its own internal mic, and also through my Sennheiser Lavelier mic, but not the MKE 600. I have already tried all different combinations of FPS recording formats and 4K and FHD, but in vain. Neither does it help to use MKE 600's internal battery! I guess the MKE 600 is not compatible with the 5d Mark IV (?) - Am I doing something wrong or is MKE 600 not compatible to be connected directly to the mini-jack port on a 5d Mark IV in the first place?

I thought I had this problem also. Solution, the cord from the receiver to the jack on the side of the camera wasn't plugged in properly. It took a really firm push past some initial resistance to get the cord to seat properly.

I was having this problem too…then I figured out my mic was not all the way in the Jack. Some reason on the Mark IV you have to push it in hard, it clicks once, but then it clicks twice and it really in there!

And THAT is the true solution here. Push that mic connector in REAL good. Only when your internal mic is NOT picking up any sound, you know that the external mic is connected properly.

That is how the 3-conductor connector works.  It will do a double-click as the tip passes each connecting plate.  It nay even click a thrid time when it is fully seated.

It has absolutely nothing to do with the camera or Canon.  The connector has been in use since stereo was first invented.

Yes, I know, working with AV for decades now, but I must admit that it takes real force to get the MIC plug into the 5D properly.
