Take your music to the next level with the Quantum ES4 audio interface bundle from PreSonus. This complete recording package equips you with everything needed to lay down studio-quality tracks at home, on the road or wherever inspiration strikes. The Quantum ES4 interface forms the centerpiece, combining four premium mic preamps, instrument inputs tailored for guitar and bass and a wealth of pro features into a compact, mobile-ready design.

Pristine Recordings With MAX-HD Preamps

At the heart of the Quantum ES4 are four newly designed MAX-HD mic preamps that provide transparent, low-noise amplification across the entire frequency range. With a huge 75dB of gain on tap, these preamps easily handle even the most demanding microphones while maintaining impeccable clarity. You can record vocals, acoustic guitar, drum overheads and more with stunning realism—capturing every nuance as if you were in a world-class studio.

Guitar and Bass Tones Honed by the Masters

To ensure the Quantum ES4 accurately translates the character of your guitar or bass tone, PreSonus collaborated with the engineers at Fender. The instrument input was meticulously voiced to provide the most faithful representation when plugging in electric or acoustic-electric instruments. Every delicate overtone and percussive attack rings true, making the ES4 an ideal recording companion for discerning guitarists and bassists.

Effortless Setup With Auto Gain

Dialing in gain levels is crucial for clean recordings, but can be tricky—especially when tracking multiple sources simultaneously. Thankfully, the Quantum ES4's Auto Gain feature takes the guesswork out of setting levels. Simply press the button and the interface automatically adjusts the preamp gain for each input to optimal levels. You can concentrate on your performance while Auto Gain ensures flawless takes every time.

Total Control Via Universal App

While the Quantum ES4 interface packs an array of hardware controls, the included Universal Control app opens up even more functionality. Use it to adjust preamp gain, toggle phantom power, tweak input/output levels and more—all from your mobile device or desktop. With full wireless control over your recording rig, you're free to move about the room and make adjustments without interrupting your flow.

Monitor With Confidence Using Yamaha Accuracy

To complete this studio bundle, PreSonus paired the Quantum ES4 with a set of Yamaha's renowned HS series studio monitors. Choose between the HS5, HS5SG or the HS8 to deliver the power you need. With their flat frequency response and precise dispersion, these monitors deliver an honest representation of your mix—revealing any flaws while ensuring your tracks translate reliably across different playback systems. The included monitor stands provide optimal positioning, while cables connect everything for a compact yet powerful recording setup.

Whether you're a singer-songwriter, producer or multi-instrumentalist, the Quantum ES4 bundle gives you an all-in-one recording solution with uncompromising quality. With premium components and intelligent workflow features, you have everything needed to capture inspired performances and pristine audio anywhere.
