Using AUX port on S11 to connect to external recorder

Hello, my question is that I want to record my set using the AUX port on the S11, where I connect a Zoom recorder to the AUX port.  I understand that the AUX port is for input, but there is a lot of information on the internet stating that you can route audio out to the AUX port. Is this possible and, if so, how to set it up?
