Using Presonus' StudioLive Series III Rack Mixers as a Digital IO for your DAW can be tricky to set up, and unfortunately the documentation is written with a strong bias toward explaining how the full mixers work, while being less precise about the smaller rack-mount cousins, the 16R, 24R and 32R. This video demonstrates how to set up Presonus Studio One 5 to be able to hear what has already been recorded in Studio One on the 24R as additional tracks are laid down.
