The Presonus Studio 1824 is a USB 2.0 audio/MIDI interface capable of recording up to 18 simultaneous inputs at up to 24-bit / 192 kHz and offers XMAX Class-A preamps, ADAT I/O, and S/PDIF I/O. Its 18 outputs offer flexible routing with zero-latency DSP-based monitor mixing and control-room integration with the included Studio One Artist for Mac and Windows, and UC Surface for Mac, Windows, iPad, and Android. The interface features mute and level controls for the main output, two headphone outputs with independent mix streams, a BNC word clock output, and MIDI I/O with 5-pin DIN connectors.
