PreSonus Quantum Thunderbolt Audio Interface

The PreSonus Quantum Thunderbolt Audio Interface is a 24-bit, 192 kHz audio/MIDI interface that offers a wealth of advanced features and takes advantage of the high-speed Thunderbolt 2 bus and ADAT Optical I/O to deliver up to 26 inputs and 32 outputs, with extremely low latency.

The PreSonus Quantum Thunderbolt Audio Interface is loaded with high-headroom, Class A, digitally controlled XMAX™ microphone preamplifiers, an ultra-low latency Thunderbolt recording and playback engine, talkback, monitor functions, and more. It breaks new boundaries for musical performances and productions. All you need is a computer with a Thunderbolt connection, a few microphones and cables, powered speakers, and your creativity, and you’re ready to record, mix, and release your music.

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 PreSonus 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 PreSonus 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 PreSonus Quantum Thunderbolt audio interface is an ideal recording solution for any size of studio. With that in mind, PreSonus 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
PreSonus 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.

The Quantum Leap
Industry-leading speed and pristine audio quality combined with jaw-dropping expandability are the hallmarks of the PreSonus 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.
