PreSonus Quantum 26x32 Audio Interface

Taking full advantage of the high-speed Thunderbolt 2 bus, the PreSonus Quantum 26x32 Thunderbolt Audio Interface audio/MIDI interface delivers extremely low latency and superb audio quality, with 24-bit, 192 kHz recording and playback; converters with better than 120 dB of dynamic range; and eight of PreSonus' famous recallable XMAX preamps. You get 2 combo mic/instrument/line inputs, 6 combo mic/line inputs, 2 TRS main outputs, 8 TRS line outputs, stereo S/PDIF digital I/O, 16-channel ADAT Optical I/O (8 channels at 96 kHz), and two stereo headphone outputs for a total of up to 26 inputs and 32 outputs. All analog outputs are DC coupled and can deliver control voltages for analog gear. You also get Main Mute/Dim and Mono functions plus a Talkback system with an internal mic. Using the included Studio One Artist DAW or UC Surface control software, you can remote-control the preamps and many other features. If your needs grow, you can stack up to four Quantum interfaces to create a monster system with up to 96 in and out.

Get a closer look at the Quantum audio interface in this video from PreSonus:


PreSonus cuts the wait.

Every design decision during Quantum's engineering was made with one goal in mind: speed. Quantum sports high-speed Thunderbolt 2 connectivity and a no-frills, direct-to-daw architecture, with no DSP. The result is our leanest, fastest, lowest-latency interface to date. Cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range and a surprising amount of expandability and software control options round out the package.

Expandable when you need more I/O -- up to 96 in and out.

The Quantum offers two combo mic/line/instrument inputs and six combo mic/line inputs, each with a digitally-controlled XMAX preamp and individual +48V phantom power. You also get two 1/4" TRS main outputs, eight 1/4" TRS aux outputs, and two independent headphone outs with dedicated volume controls. But that's just the start. With ADAT Optical I/O and S/PDIF stereo digital I/O, you can have up to 18 digital inputs and outputs. And if you need even more I/O channels, you can stack up to four Quantum interfaces via Thunderbolt to create a monster system with up to 96 in and out. BNC word clock I/O ensures your Quantum and other digital audio devices operate in tight sync. And of course you get MIDI I/O, too.

Superior sound.

Audiophile-grade digital converters, low-jitter clocking, and recallable preamps add up to a superior recording and listening experience. The Quantum 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.

A superior choice for any production environment.

With its pro features and abundant I/O, the Quantum fits into any recording and production environment. You get two main and eight auxiliary balanced line-level outputs, as well as Mute/Dim and Mono controls. The onboard talkback mic can be routed to any mix, and you can listen to any mix from either of two independent headphone amps. All 10 analog outputs are DC coupled so they can provide control voltage to external analog equipment. Add that to Quantum's expandability, flexible software suite, blazing speed, and superb sound quality, and you have a recording system that will be the heart of your dream studio for years to come.

Tight integration with Studio One.

With the Quantum, your audio interface is an integrated extension of your recording environment. Launch Studio One, and you'll find full preamp control integrated into your recording environment. Need to track away from your computer? Launch Studio One Remote on your iPad.

Remote control with UC Surface, too!

The Quantum's onboard 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 them. PreSonus even included a real-time analyzer to monitor your audio streams. UC Surface has rapidly won accolades for an intuitive mixing interface that provides quick access to everything you need.
