Presonus Quantum ES 4 Audio Interface

General

With the Quantum Series, PreSonus introduces their first line of desktop audio interfaces. The Quantum ES 4 has been designed for more ambitious producers and musicians, and features four XLR/TRS combo inputs and four balanced TRS outputs. This USB-C interface can be connected to virtually all modern computers and laptops and, since it's powered by a set of upgraded MAX-HD preamps, it captures sound in 24-bit/192 kHz quality, meaning you won't miss out on any details.

Fender®-Developed High-Z Instrument Inputs

While only recently acquired by Fender, PreSonus is already reaping the rewards. The Quantum ES 4 has been outfitted with two Fender-designed, high-Z instrument inputs, which boast a satisfyingly fast response and ensure a clean DI signal. Another practical feature is the built-in Auto Gain function which, as the name suggests, automatically sets the input level so that you don't have to worry about clipping, keeping the audio undistorted at all times.

Universal Control App

The PreSonus Quantum ES 4 can be controlled via the Universal Control App, which lets you access essential functions and settings - including the preamp gain and phantom power supply - from the comfort of a mobile device. Every interface also comes complete with a six-month subscription to Studio One+, which hooks you up with Studio One Professional and add-ons so you can start writing, recording and producing right away.
