I have a 3DIO FS XLR and I'm using brand new Hosa XLR cables with the mic. When I'm talking into the right ear, it makes an unattractive cackling sound and sometimes the audio just cuts off. This only happens when I'm using XLR cables but not when I'm using 3.5mm cables.

Hi @li yu,
Thank you for reaching out to us. I'm sorry to hear you are experiencing this issue.
Was the microphone working properly when you received it?
Are you applying 48V phantom power to the XLR outputs?
What equipment are you plugging the microphone into?
What are the settings on the device you’re connecting to the 3Dio?
Are there any adapters in use?
Feel free to send pictures or a video of your audio setup if that’s easier.
Also, please check out our tutorial videos on YouTube for help with different audio setups:

Was the microphone working properly when you received it? When I first got the mic, I always used the 3.5mm cable and I tried using XLR cables some months ago, and the right ear was cackling since then so I stopped using XLR cables.
Are you applying 48V phantom power to the XLR outputs? I am not applying 48V phantom power, I'm only using the direct monitor double green circles.
What equipment are you plugging the microphone into? I am using scarlett 2i2 audio interface with XLR cables
What are the settings on the device you’re connecting to the 3Dio? I am using scarlett 2i2 audio interface with XLR cables
Are there any adapters in use? My setup is just 3DIO fs xlr and scarlette 2i2 with XLR cables
Hi @li yu,
Thank you for the additional info.
The reason why you're getting the crackling sound is because you're not applying 48V phantom power to the microphone when connecting the 3Dio to the Scarlett using XLR cables. 3Dio microphones are like most studio condenser microphones in that they require phantom power in order to properly function (when using the XLR outputs).
The battery inside the 3Dio only applies to the 3.5mm output and does not power the capsules when using the XLR jacks. The battery allows for remote recording for outdoor use or whenever a phantom power source is unavailable.
My guess is that you had to increase the volume/gain settings on your device in order to get any audio from the XLR outputs, correct? Once you enable the phantom power on the Scarlett, the audio output of the mic should be much louder without any crackling noises.
Give this a try and let us know if that doesn't resolve the issue.
Best regards,
