The PreSonus Quantum ES 2 audio interface represents the culmination of nearly 30 years of innovation in digital recording. This 2x2 USB-C interface gives you pristine 24-bit/192kHz audio quality with PreSonus' latest breakthroughs in preamp design, converter technology and ultralow latency drivers. Whether you're recording vocals, guitar or any other instrument, the Quantum ES 2 delivers professional sound in an ultraportable package perfect for the modern home studio.

PreSonus Quantum ES2

Next-Generation MAX-HD Mic Preamps

At the heart of the Quantum ES 2 are two newly designed MAX-HD mic preamps that set a new standard for transparency and gain. With an incredible +75dB of digitally controlled analog gain on tap, you can easily handle everything from whisper-quiet vocals to blistering guitar amps. Yet these preamps remain clean and neutral even when pushing higher gain levels. Their cutting-edge design combines the best of analog and digital to deliver maximum headroom with minimum noise and coloration.

PreSonus Quantum ES2Front Panel Input

Fender-Approved Instrument Input

Plug your guitar or bass straight into the Quantum ES 2's dedicated front-panel instrument input. This 1/4" jack was codesigned by the tone experts at Fender to provide an ultrapure signal path optimized for your electric or acoustic-electric instruments. You'll hear every nuance and harmonic detail captured with stunning clarity. With such a high-fidelity front end, the Quantum ES 2 is an outstanding choice for D.I'ing instruments when recording in the studio or performing live. 

PreSonus Quantum ES2 With Computer

Effortless Level Setting With Auto Gain

One of the handiest features of the Quantum ES 2 is the Auto Gain button. With a single press, it automatically sets the perfect input gain level for your microphone or instrument. No more fiddling endlessly with trim knobs—Auto Gain gets you dialed in for optimal recording levels at the press of a button. The illuminated push encoder also gives you quick visual feedback and precise manual control over gain and output volume.

High-performance converters ensure your audio remains stunningly clear from input to output. With its near-zero latency, you can confidently track with virtual instruments, record vocals over loops or monitor effects in real time without distracting delays or comb filtering.

PreSonus Quantum ES2 Studio One+ Software

    It's a very nice interface. I have used it for plugging in my electric guitar to use with a amp simulator plug-in. It Works great. Sounds better than my mixer interface. Fuller better sound. No noticeable latency at all. The auto gain feature comes in handy. Plus it looks very cool

    Straight forward usb audio interface, little different design but very high quality. I like how there is only one knob to adjust levels and you have to select first what you want to adjust. Cool leds to indicate levels.

    Now this is very much a case of a faulty unit, but my point still stands. I spent a good 2 weeks trying to get the usb to work. Eventually had to buy a new USB cable as apparently the one it came with was faulty. Even after that, the software was able to pick up that this was plugged in, but no audio would come through it at all. Spent a good while trying absolutely everything to get it to work, but nothing did. They also could have included the second cable you need in order to get this to work, but chose not to. Ended up having to return it. Besides that, this definitely is well built, and the auto gain feature is very nice. If I didnt happen to get a faulty unit I probably would have loved this thing. Wasnt for me, but hopefully this works for someone else.

    1) I’m sorry, I don’t know. Perhaps an inquiry to Presonus.. There is no internal clock.

    Does this convert guitar recording to midi digitized sound on the DAW recording? Analog-to-digital capability?

    No, it doesn't. That would require a midi pup - Roland GK-KIT-GT3 GR-Synth Driver Kit
