The PreSonus Quantum ES2 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.

Next-Generation MAX-HD Mic Preamps

At the heart of the Quantum ES2 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.

Fender-Approved Instrument Input

Plug your guitar or bass straight into the Quantum ES2'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 ES2 is an outstanding choice for D.I.'ing instruments when recording in the studio or performing live.

One of the handiest features of the Quantum ES2 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.
