PreSonus StudioLive 24R 46 x 26 Digital Rack Mixer

The StudioLive 24R digital mixer is four audio tools in two compact rackspaces. Use it as a standalone digital mixer with UC Surface remote mixing software. Pair it with your StudioLive Series III console mixer to use as a stage box or integrated monitor mixer. Connect it with EarMix 16M monitor mixers for the ultimate personal monitor system. And of course, Just like other StudioLive Series III digital mixers, the StudioLive 24R is a continuously bidirectional, 128-channel (64x64) USB audio interface. Whether used standalone or as part of a complete audio system, no other rackmount digital mixer is as flexible or as powerful.
