The Studio 1824c audio interface features USB-C™ compatible computer connectivity and records up to 18 simultaneous inputs, including two combo mic and switchable line/instrument inputs and six mic/line inputs, all with XMAX mic preamps and +48V phantom power. Digital inputs include eight channels of ADAT Optical I/O (four channels at 96 kHz) and stereo S/PDIF I/O. In addition to the main L/R outputs, you get eight DC-coupled line-level outputs that can send control voltages. You also get two headphone outputs. A built-in MIDI interface enables connection to a keyboard, sound module, or control surface.
