PreSonus Quantum 2 is slightly smaller than the original Quantum, and shares its larger sibling’s status as PreSonus’ fastest and best-sounding audio/MIDI interface, taking advantage of the high-speed Thunderbolt 2 bus and a no-frills, direct-to-DAW signal path to achieve extremely low latency. Cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range and PreSonus’ recallable XMAX microphone preamps combine to deliver superb audio quality. For more I/O channels, simply stack up to 4 Quantum 2 interfaces via Thunderbolt to create a monster 80×80 system.

The Quantum 2 offers two combo mic/instrument inputs and two combo mic/line inputs, each with a digitally controlled XMAX preamp and +48V phantom power. You also get four ¼-inch TRS line outputs, and a headphone output with dedicated volume control. With ADAT Optical I/O and S/PDIF stereo digital I/O, you can have up to 18 additional digital inputs and outputs for a total of 22 in and 24 out. BNC word clock I/O ensures your Quantum 2 and other digital audio devices operate in tight sync. Of course, you get MIDI I/O, too.

With the Quantum 2, your audio interface is an integrated extension of your recording environment. Launch the included PreSonus Studio One Artist DAW, and you’ll find full preamp control functions integrated into your recording environment. Most of the Quantum 2’s features can also be controlled in PreSonus’ free UC Surface control software, so even if you use third-party recording software, you can remotely access the features. To top it off, Quantum 2 owners get the Studio Magic Plug-in Suite free.

Thanks to its pro features, flexible software, and abundant I/O, the Quantum 2 joins the original Quantum as PreSonus’ most powerful combination audio interfaces/studio command centers and fits into any recording and production environment.
