PreSonus®’ 24-channel Series III StudioLive® 24R is both a versatile AVB stage box for StudioLive Series III consoles and the most powerful rack mixer in its class. It can operate as a simple stage box or as a combined stage box/monitor mixer, including remote control of the preamps and phantom power from the Series III console. As with Series III consoles, it’s fully recallable and features a plug-in-style signal-processing workflow with vintage-style EQ and compression options on every channel; 16 FlexMixes that can be Aux, Subgroup, or Matrix mixes; 4 fixed subgroups; 6-band fully parametric EQ on all mix outputs; and built-in AVB networking. In addition to 40x40 USB and 55x55 AVB recording interfaces, the StudioLive 24R features an onboard stereo SD recorder.
Below are the minimum computer-system requirements for UC Surface, QMix®-UC, and Studio One®.

“Obviously, I love using this unit as a stage box, but where I think this little rack unit would shine would be either in a portable system or in a venue where you don’t necessarily have a great space (or a well-placed space) for a sound desk.”
