PreSonus Quantum ES 4 USB-C Audio Interface

The Quantum ES 4 is the ultimate audio interface for serious creators—designed from the ground up with the needs of modern musicians, producers, and content creators in mind. At its heart are four newly redesigned MAX-HD mic preamps with an impressive +75 dB of gain, delivering crystal-clear performance even with gain-hungry mics like the SM7B. Whether you're recording vocals, instruments, or podcasts, you'll capture every detail with stunning clarity.

Guitarists and bassists will appreciate the instrument inputs co-developed with Fender®, offering authentic tone and response that honors your sound. With the touch of a button, Auto Gain automatically sets your levels, so you can focus on creativity instead of tweaking knobs.

A bright, responsive LED meter display gives you instant visual feedback on your input and output levels, and the illuminated push encoder makes it easy to dial in gain or adjust output volume with precision. Whether you’re in the studio or recording solo, the Quantum ES 4 puts professional sound at your fingertips.
