Can someone tell me what audio inputs and outputs this device has?

I want to plug a microphone and a guitar into the device. is that possible.

I’d also like a low-z output and a headphone output (possibly using the speaker output).

Nothing I can find shows what audio inputs and outputs are available.

Hey there and welcome to the CircuitMess community!

Jay-D only has the in-built speaker and a 3.5mm jack output intended for use with headphones. The 3.5mm output can give a maximum 3W power and when it is plugged in the speakers get cut off, so only one output is active at a time.

Let me know if this answers your questions or if I can be of further assistance.
