Presonus Quantum Thunderbolt 2 Audio/MIDI Interface

Your expandable, ultra-high definition recording system
Taking full advantage of the high-speed Thunderbolt 2 bus and ADAT Optical I/O, the PreSonus Quantum audio/MIDI interface delivers up to 26 inputs and 32 outputs, with extremely low latency. Boasting superb audio quality; 24-bit, 192 kHz recording and playback; recallable XMAX microphone preamps; and the ability to expand your system as your needs grow, it's a great choice for a wide variety of professional and semi-pro producers and electronic musicians.

We cut 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. The Quantum's eight analog inputs, ten line-level analog outputs, two stereo headphone outputs and stereo S/PDIF digital I/O might be all you need today. But your studio is likely to grow in time and so can your Quantum recording system. Its dual ADAT Optical I/O provides up to 16 more channels of digital I/O at up to 48 kHz (up to 8 channels at 96 kHz).

The Quantum's ADAT I/O lets you add any ADAT-compatible A/D/A converter but we highly recommend the PreSonus DigiMax DP88 preamp/converter, which seamlessly extends the analog I/O on the Quantum with eight digitally-controlled XMAX preamps and word clock I/O. The DP88's mic preamps are fully remote-controllable from UC Surface, Studio One and Studio One Remote when connected via ADAT Lightpipe to the Quantum so that they naturally extend your analog inputs both sonically and functionally. If your studio grows even more, you can stack up to four Quantum interfaces via Thunderbolt. This enables you to create a monster system with up to 96 in and out-more than enough to cover almost any studio's recording needs.

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.
