Introducing the ES tabletop series.
A giant leap forward into the next generation of PreSonus audio interfaces and the culmination of nearly 30 years of pro audio equipment design, Quantum ES 2 and Quantum ES 4 are the ultimate tools for self-produced recording and studio-quality music production.
The new face of desktop recording.
Ergonomic tabletop chassis packed with pristine MAX-HD preamps and class-leading converters for self-made audio creators.


Low-latency. High performance.
Quantum's custom drivers provide exceptionally low signal lag when recording, while high-performance converters and powerful headphone outs complete the front end — ensuring flexible audio monitoring and superior sound throughout your entire signal chain.


Flow-friendly front panel.
Plug into instrument inputs co-developed by Fender engineers and specifically designed for guitar and bass, then start studio-quality recordings fast by setting perfect gain levels on your mics and instruments with easy-to-use Auto Gain.


Quantum ES4
All the connections you need—highlighted by two or four newly redesigned MAX-HD mic preamp inputs delivering transparent, low-noise, digitally-controlled analog. With +75 dB of gain range, MAX-HD mic preamps are ideally suited for today’s most popular mics.
Pro DAW, control app, and more included.


Access to Studio One Pro recording software included with all Quantum interfaces.
Quantum interfaces include completely free, 6-month (Quantum ES) or 12-month (Quantum HD) memberships to Studio One Pro+, a complete music production ecosystem including access to Studio One Pro recording software, collaboration tools, sample and loop libraries, add-ons, and exclusive learning content. No credit card required. And with Quantum HD interfaces, you'll also get a Studio One Pro Perpetual License—yours to keep after your 12-month membership ends.
