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.
