Turbocharge your recording power with the Presonus Quantum Thuderbolt Audio and MIDI Interface. Complete with high-speed Thunderbolt and ADAT Optical I/O the Quantum interface is capable of up to a whopping 26 inputs and 32 outputs, all with near-zero latency. Audio quality is absolutely paramount and at 24-bit, 192kHz recording and playback you'll achieve professional results every-time.

Harder, better, faster

When the Presonus engineers were producing the Quantum speed was at the forefront of their minds. A direct-to-DAW architecture was put in place with no DSP so that you will get one of the lowest latencies on an interface to date, even with the staggering amount of connectivity.

Offering two combo mic/line/instrument inputs and six combo mic/line inputs, each with digitally-controlled XMAX preamps and channel specific +48V phantom power, you have the power to record a whole band simultaneously directly into your DAW of choice. For outputs, the Quantum showcases two quarter inch TRS main outputs, eight quarter inch TRS aux outputs and two independent headphone outs with independent volume controls for each set.

The inclusion of ADAT Optical I/O and S/PDIF stereo digital I/O, you can have up to 18 digital inputs and outputs and this can be further increased when you stack Quantum units together meaning that this unit can grow with your studio requirements.

One size fits all

Whatever your production environment the Presonus Quantum will fit to your needs effortlessly thanks to its MIDI, digital and analog capabilities. A built in talk-back mic means you can communicate with your studio artist(s) thanks to flexible routing and they in turn can communicate with you via your headset.

In terms of software, whilst the Presonus Quantum can be tightly integrated into the included Studio One Artist DAW software, it will also work in perfect harmony with any digital audio workstation of your choice and will always deliver staggering results.

Finally, bundled with the Quantum is the Studio Magic plugin suite that contains virtual instruments and effects from companies such as Eventide, Lexicon, Arturia and more to breathe some extra magic into your productions.

The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.

Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio signals.
