Presonus Quantum ES4 USB-C Audio Interface

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.
