Analog Four - how to record without computer

Hi there - just a quick question, I want to use a field recorder and plug it directly into the A4, is this possible? What cable would I need for this?

The whole idea is that I don’t want to use the computer at all and if just jamming with the A4 then just plugging the recorder into it would be perfect.
Also, as I would connect this via cable for recording mp3 then a low budget recorder would do I guess, but which one?

Many thanks for your help!
