USB2 / TRRS adaptor

[posiview]

Hi, I've just bought a SJ4000 and already have an external mic. The mic connects using a TRRS jack and the SJ4000 has USB2 and HDMI ports. I've been trying to find a way to use the mic with the SJ4000 without any luck,

Any ideas/recommendations?

Thanks.

USB2 and HDMI are digital. You'd need an analogue to digital converter and an audio embedder.

Better to add a 3.5mm jack.
