PreSonus Quantum

A great choice for a wide variety of recording environments, the 26x32-channel Quantum is PreSonus® fastest and best-sounding audio interface, taking advantage of the high-speed Thunderbolt™ bus and a no-frills, direct-to-DAW (no DSP added) signal path to achieve extremely low latency. Two combo mic/instrument/line inputs and 6 mic/line inputs with recallable XMAX preamps combine with cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range to deliver superb audio quality. For more I/O channels, simply stack up to 4 Quantum interfaces via Thunderbolt to create a monster 96x96 system. You also get MIDI and word clock I/O. Using the included Studio One Artist DAW or UC Surface control software, you can remote-control the preamps and many other features. To top it off, Quantum owners get the Studio Magic Plug-in Suite free and can upgrade to Studio One Professional for 50% off.
