The speed of sound.
With a barely measurable round trip latency of less than 1 ms*, it's no wonder Sound on Sound magazine dubbed the Quantum Thunderbolt™ 2 audio interface the fastest audio interface on the planet. Superb high-definition digital conversion and ultra-transparent XMAX-Remote mic preamps mean that your audio will always sound its best—whether you’re recording with or without your favorite plug-ins engaged in real-time.
Timeless audio.
Every design decision during Quantum’s engineering was made with one goal in mind: blazing fast speed without any sonic compromise. The Quantum-series proprietary Thunderbolt driver was written from the ground up to deliver ultra-low-latency performance while maximizing efficiency. Cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range and superior low-jitter clocking, coupled with our ultra-transparent XMAX-Remote preamps, result in superb audio quality with the lowest roundtrip latency of any audio interface available (< 1 ms*).

Superior sound. Sublime recall.
Audiophile-grade digital converters, low-jitter clocking, and recallable preamps add up to a superior recording and listening experience. The Quantum audio interface operates at up to 192 kHz for ultra-high-definition mixing and recording. High-quality converters on every input and output provide 120 dB of dynamic range to capture complex musical harmonics smoothly and naturally with no audible distortion. And our recallable XMAX Class A analog microphone preamps deliver incredibly high headroom, deep lows, smooth highs, and a rich overall sound so you’ll hear every breath, transient, and detail in your recordings.
Expansive audio.
Impressive speed combined with stunning sound quality means that the Quantum Thunderbolt audio interface is an ideal recording solution for any size of studio. With that in mind, we designed Quantum-series interfaces to be stacked with one another for up to 192 inputs and outputs. Need more mic preamps? Connect the PreSonus DigiMax DP88 to your Quantum interface’s ADAT/dual S/MUX ports. Once synced, the DigiMax DP88 preamps can be remote controlled via Studio One or UC Surface just like the onboard preamps.

Seamless integration.
Quantum Thunderbolt audio interfaces are fully integrated with Studio One® to provide unparalleled control over your hardware right from your recording environment. Launch Studio One, and you’ll find full preamp control, talkback, and speaker switching integrated into your Studio One console. Need to track away from your computer? Launch Studio One Remote on your iPad® or Android™ tablet. Quantum preamps can be also controlled via MIDI in Pro Tools, Logic, or Live so you can save the settings with your recordings.
Quantum users receive a complementary license for Studio One Artist with their registration, plus 50% off upgrades to Studio One Professional.
The Quantum leap.
Industry-leading speed and pristine audio quality combined with jaw-dropping expandability are the hallmarks of the Quantum interface design. Record and monitor from your favorite DAW with any plug-in engaged. Take advantage of onboard mix features like Mute, Dim, Mono, and integrated Talkback. Regardless of your studio’s size, Quantum audio interfaces streamline your recording process—you’ll make better music, faster.
Make your own magic.
At PreSonus, we want to make sure that our audio interfaces come with everything you need to craft your own mesmerizing spells in the studio. That’s why we include Studio One Artist with every audio interface product we make. But here in Louisiana, we have a word: lagniappe. It means "a little something extra," and it’s in that spirit that we also include the Studio Magic Suite of software with our audio interface products.
The 2020 Studio Magic is a major step up from the 2019 edition, and includes Ableton Live Lite, tutorials from Melodics, 6 virtual instruments, and 9 effects plug-ins in VST, AU, and AAX formats... all unlocked for use inside Studio One Artist with a retail value of over $1000 (US).
Content and terms of the Studio Magic Plug-in Suite are subject to change.
PreSonus has given DSP the boot to keep the processing path as slippery as an eel.

...zeigt, dass Innovation nicht zwangsläufig zu höherer Komplexität und immer kniffligerer Bedienung führen muss.
Dr. Andreas Hau, Sound & Recording
They've achieved low-latency performance that, with the exception of PCIe cards, is currently unrivaled by any interface I know of.
Sam Inglis, Sound on Sound
We quickly launched a previous session that had been problematic for two other USB and Firewire interfaces. Not only did that session run flawlessly using the Quantum, we added another 50 tracks and put them into record with no problem whatsoever!
