PreSonus Quantum ES 4

TAKE THE LEAP.
The art of audio meets the science of sound.

Take a sonic leap with the Quantum ES 4. The next generation of PreSonus audio interfaces, the Quantum ES 4 is the culmination of nearly 30 years of PreSonus expertise, providing the ultimate recording tool for musicians and content creators.

The Culmination Of 30 Years Of Innovation
The ES 4 features four newly redesigned high-definition MAXHD mic preamps with +75 dB of gain – making it ideally suited for today’s most popular microphones. Guitarists and bassists will love the instrument inputs, which were co-developed with Fender engineers. An Auto Gain button sets the perfect gain level for your microphones and instruments, while an illuminated push encoder provides flexible control over gain level and output volume. And bright and responsive LED metering provides easy visual feedback for your inputs and outputs, making it great for self-produced recording.

High Performance Signal Flow
Our custom low-latency driver provides exceptionally low audio latencies when recording, and high-performance converters complete the front end to ensure that you sound your best throughout the entire signal chain.

All-New MAX-HD Mic Preamps
The Quantum ES 4 features four newly designed mic preamps with +75 dB of gain. Our high-definition MAX-HD preamps are transparent, low-noise, and digitally-controlled analog, making them ideally suited to today’s most popular microphones.

Co-Developed With Fender®
Built by the best ears in the business, guitarists and bassists will love the instrument input co-developed with Fender engineers – industry experts who designed them specifically for guitar and bass.

Professional Recording Software Included
Leap into 6 months of Studio One+ with access to Studio One Professional Edition, add-ons, and more.

Auto Gain
An Auto Gain button sets the perfect gain level for your microphones and instruments, so you get the perfect take every time.

Universal Control App
Quantum works on any mobile or desktop device, so you’re ready to record whenever inspiration strikes – whether on your phone, tablet, or in your home studio. Critical preamp functions like preamp gain, phantom power, and more can be controlled with the Quantum ES 4’s top panel, or right from Studio One and the Universal Control app, so you can dial in the perfect gain staging without looking away from your recording session.
