Recording audio from Hercules Starlight DJ controller

I have a MacBook running El Capitan with a Hercules Starlight DJ controller and Virtual DJ and want to capture the output but Audacity doesn’t grab any sound. It does recognise the controller as a sound device so I’m wondering if I’d need any additional cables to route the audio differently?

The DJ console uses 3.5mm jack’s.

The first step is to go to Apple menu > System Preferences > Sound > Input. Is the controller in the list there? If you play sound with the controller does the audio meter bounce? See the first illustration on this wiki page.
