Hi Chess,

Thank you for your message. First, have you been able to do a test call using your Mac Mini and a simple set of wired headphones (like the wired Apple EarPods) (see instructions)? That basic setup is good for troubleshooting things before setting up an advanced mixer, like your L-20.

Thank you,
David Liao
