Can't record Using Canon EOS M50

  • I bought a 3Dio microphone to use for my YouTube channel. I directly connected the 3Dio mic with a 3.5mm cable to my M50 microphone jack, but I can’t seem to get it to work. The 3Dio manual says some devices (smartphone, computer) need the 3Dio to connect to a preamplifier first, then connect the preamp to the recording device. Does anybody know if the Canon EOS M50 has a preamplifier for the mic jack? Basically, do I need to buy a preamp to get the 3Dio to work with my M50? If not, any ideas why I can’t get the M50 to record sound when I connect the 3Dio directly to the microphone jack. I do connect a Blu Yeti directly to the M50, so I know the mic jack works.

    Thank You

    Hi @Eric Hanson ,

    Thank you for your question. Some cameras are compatible with external stereo microphones and others are not. When viewing the Canon EOS M50 Product Manual, there is no information regarding what type of microphone is compatible, whether the external mic input supports stereo audio, or even if the camera contains a pre-amp...at least that we could find. You can find the product manual here. Have you reached out to Canon support team for assistance?

    The Blue Yeti has its own headphone amplifier for direct monitoring, which is why it most likely works with the camera. This output is a line level output and doesn't require a preamp, because it's built into it. The 3Dio output is a mic level output so you can use your own preamp without compromising quality.

    If you intend to record directly into your computer, we recommend the Focusrite Scarlett 2i2 as a stereo audio interface. This device contains both a preamp to boost the signal to line level as well as an A/D converter so you can record digital audio directly to your hard drive.

    Another option, is the Zoom H1n. It is a small, stereo digital recorder that you can use to record onto a micro SD card or you can use it as an audio interface connected to your compauter as well. It is portable and light weight and provides really great quality and convenience for the price.

    I hope this information helps. Let us know if you have any other questions.

  • Thank you, I appreciate the quick response!. Unfortunately, I couldn’t find anything either in M50’s manual. However, I have a support ticket open with Canon asking if the M50 supports the 3Dio, or has a preamp; I suspect it doesn’t and will need to purchase one. Also, thank you for the preamp recommendations; I will look at them while waiting to see what Canon has to say.

    Ah, yes, I think I remember reading the Blu Yeti has its own amplifier.


  • @Eric Hanson Have you found any solution for this? I would like to record audio without purchasing anything extra and just recording directly into my m50 as well. 

    Also if you plug the XLR version into a camera using an adapter, would it downgrade the signal or would you retain the same higher quality benefits of the XLR?

    @Joon Huh,

    To answer your question regarding the XLR adapter, we do not recommend downgrading an XLR output (balanced) to a 3.5mm input (unbalanced) for any scenario. Not only will you not retain the benefits of the XLR quality as you mentioned, but you actually will not receive a loud enough signal as the XLR outputs on the 3Dio require phantom power from the camera or audio device it is connected to in order to boost the signal to an audible level. The 3.5mm output of the 3Dio is powered by the 9V battery inside the microphone while the XLR outputs require phantom power from an external source. There are no devices on the market that provide phantom power using a 3.5mm stereo input.

    Let me know if you have any other questions.

    Best regards,
    3Dio Customer Care
