As home recording technologies advance, so do the creative possibilities of artists and content creators. PreSonus’s Quantum ES 2 distills three decades of aural innovation into a powerful, flexible audio interface, primed for performance with unrivaled 24-bit/192kHz resolution. Its 2-channel design includes a pair of dual microphone and line inputs, as well as a dedicated guitar input that was co-designed with Fender. Recording experts at Sweetwater are enamored by the interface’s masterful mix of ergonomics and sleek aesthetics, providing real-time LED feedback alongside a streamlined, user-friendly interface. Surface controls are optimized to maximize detail and control, crafted with a satisfying tactility to seamlessly dial in your setup. With versatile recording tools, custom-built low-latency drivers, robust analog mic preamps, and MIDI capabilities, the Quantum ES 2 stands to upgrade any studio setup with uncompromising fidelity and control.

State-of-the-art sound and style

Beneath its elegant form factor, the Quantum ES 2 contains an armada of premium recording tech. Custom-designed low-latency drivers are complemented by high-caliber converters to maximize clarity and signal preservation, ensuring that audio is crystal clear and brimming with detail from input to playback. For its pair of combination mic/line jacks, PreSonus debuted their next-gen MAX-HD preamps, capable of up to +75dB of gain across a formidable 20Hz–20kHz range, resulting in unmatched transparency and clarity via digitally attenuated analog character. With impressive preamp gain, phantom power, and further controls, the flexible interface seamlessly accommodates a diverse array of microphone styles and vocal deliveries for live, studio, and broadcast excellence. What’s more, the Quantum ES 2’s Auto Gain capability dials in the optimum gain levels for microphone and instrument signals, teeing you up for the perfect take every time.

Elegant interfacing with Fender-designed finesse

Through a collaborative effort with Fender, the Quantum ES 2 was engineered to facilitate recording for virtually any style and environment, including a front-mounted instrument input and headphone output, providing guitarists and bassists with pain-free, plug-and-play accessibility. Onboard LEDs give users color-coded real-time feedback through a thoughtfully arranged interface, intentionally designed to deliver relevant details without distraction. To expand the interface’s interoperative potential, the Quantum ES 2 features 3.5-millimeter MIDI I/O, while its balanced stereo output jacks are DC-coupled, opening the possibility of sending CV signals to compatible modules, synthesizers, effects units, or pedals. Plus, the Quantum ES 2 includes a built-in Loopback capability, making quick work of crafting monitor or streaming mixes.

PreSonus Quantum ES 2 Features:

  • Versatile 2-in/2-out interface utilizes cutting-edge design and lightning-fast USB-C connectivity to support multitudes of creative possibilities in any studio arrangement
  • Elegant form factor blends ergonomic accessibility with a minimal footprint, ensuring maximum control without sacrificing real estate in your setup
  • Co-designed by Fender to include a dedicated, front-mounted instrument input, affording guitarists and bassists a flexible, clear plug-and-play architecture
  • Auto Gain function matches gain levels for your mic or instrument signal to optimize input for peak-free recording
  • MAX-HD preamps supply next-gen clarity via digitally controlled analog processing with up to +75dB of gain and unrivaled transparency
  • Loopback support means monitor and streaming mixes are painlessly produced whenever needed
  • Universal Control app guarantees comprehensive control over interface capabilities to make solo, group, live, studio, and broadcast capture a breeze
  • Rear-mounted 3.5mm TRS MIDI I/O expand production, composition, and recording opportunities to accommodate numerous styles and configurations
  • Vivid LED metering provides a balance of detailed information in real time, without disrupting your recording experience
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
