The PreSonus Quantum ES4 is a sleek and powerful 4x4 USB audio interface built to help you capture your creativity with stunning clarity. Packed with cutting-edge technology from PreSonus' 30 years of innovation, the ES4 provides the sonic fidelity and hassle-free workflow modern musicians and producers need to take their recordings to a professional level.

Pristine Preamps Unlock Your Mic's Full Potential

At the heart of the Quantum ES4 are four newly designed MAX-HD mic preamps delivering up to +75dB of clean gain. These transparent, high-definition preamps reveal every nuance from your microphones with exceptional detail and low noise. Whether you're recording vocals, acoustic instruments or drum overheads, the MAX-HD preamps provide ample headroom to handle high-SPL sources without clipping. You'll be able to push modern condenser mics right to their sweet spots.

Dial In Perfect Levels Effortlessly

Nailing consistent mic and instrument levels is crucial for a clean recording. The ES4's Auto Gain feature takes the guesswork out of setting preamp gain. Just press the button and the interface automatically adjusts to the optimal level – no more fiddling with trims or risking clipping. Bright LED metering gives you clear visual feedback on levels at all times. Additionally, an illuminated push encoder puts precise gain and output volume control at your fingertips.

Capture Every Nuance With Pristine Converters

The ES4 incorporates premium 24-bit/192kHz converters to ensure your recordings have stunning depth and clarity. A custom low-latency driver keeps the signal path tight for precise tracking and monitoring. From the high-gain mic preamps to the transparent converters, the ES4's signal chain is engineered to faithfully reproduce every detail without coloration. You'll hear your mics, instruments and mix environment like never before.

Streamlined Workflow for Solo Creators

PreSonus designed the ES4 with features that enhance the self-recording process. Two high-power headphone outs let you easily dial in a separate cue mix. Loopback audio recording streamlines capturing a stereo monitor mix for live streaming or podcasting. And with the Universal Control app, you can control the ES4's functions right from your mobile device or desktop – perfect for tweaking settings without disrupting your session flow.

Whether you're recording a band, streaming a gaming session or producing a podcast, the Quantum ES4 delivers the pristine audio and flexible features to elevate your home studio. With its transparent preamps, precise converters and creator-friendly workflow, this 4x4 interface has everything you need to capture inspired performances in studio quality.
