About the PreSonus QUANTUM-ES4 4x4 24-Bit USB-C Audio Interface

The PreSonus Quantum ES 4 is a high-performance 4x4 USB-C audio interface designed for musicians and producers who require more connectivity for multi-track recording. It features four of PreSonus's next-generation MAX-Z preamps, providing an impressive 75 dB of gain to handle everything from low-output dynamic microphones to high-output instruments with pristine clarity. With professional-grade converters supporting up to 24-bit/192 kHz resolution and a 113 dB dynamic range, the ES 4 delivers the transparent, low-noise audio quality necessary for modern studio productions.

Building on the features of its smaller sibling, the ES 4 includes two front-panel instrument inputs co-developed with Fender® to ensure electric guitars and basses sound their best. It also boasts the Auto Gain feature, which quickly analyzes your input signal and sets optimal levels to prevent digital clipping. On the back, you’ll find four balanced line outputs—allowing for two sets of monitors or external gear routing—and two independent high-power headphone outputs. Like the rest of the Quantum line, it comes with a six-month subscription to Studio One+, giving you a complete professional recording and production environment out of the box.

FAQs about PreSonus QUANTUM-ES4 4x4 24-Bit USB-C Audio Interface

What is the input and output configuration of the PreSonus Quantum ES 4?

The Quantum ES 4 features 4 low-noise MAX-HD microphone preamps (combo XLR/TRS inputs, including 2 front-panel Hi-Z instrument inputs), 4 balanced 1/4" TRS main line outputs, and 2 independent headphone outputs with dedicated level controls.

What makes the MAX-HD preamps unique on this interface?

Designed with over 30 years of PreSonus expertise, the next-generation MAX-HD preamps are custom-designed, low-noise, high-definition preamps providing up to +75 dB of gain range, making them capable of driving low-output dynamic mics (like the Shure SM7B) without an external activator.

What digital audio resolution and conversion specifications does it support?

The interface features low-latency, studio-grade converters operating at up to 24-bit depth and 192 kHz sample rates with 115 dB of dynamic range, capturing pristine detail on both input tracking and playback monitoring.

What is the Auto Gain feature, and how does it work?

Auto Gain automatically sets the ideal gain levels for your microphoned sources or instruments with a press of a button. You simply press the Auto Gain button, sing or play into your mic/instrument for a few seconds, and the Quantum ES 4 sets optimum gain levels to prevent clipping.

How do the front-panel controls and software control function together?

The interface features an intuitive, tactile front panel with a multi-function push encoder and LED metering ring. Additionally, all preamp settings, gains, phantom power (+48V), and monitor mixes can be controlled directly from your DAW or via the PreSonus Universal Control app on desktop and mobile devices.

Can I record loopback audio for podcasting or streaming?

Yes, it includes built-in Loopback Audio functionality and dedicated virtual channels. This allows you to easily route internal computer sound (gameplay, video, call-in guests, or music tracks) straight into your streaming software or DAW without physical patching.

Does the Quantum ES 4 support mobile devices like iPads and phones?

Yes, it features modern USB-C 2.0 connectivity and standard class-compliance, allowing seamless plug-and-play operation with macOS, Windows, iOS, iPadOS, and Android devices.

What software bundle comes included with the interface?
