PreSonus Quantum ES 2 Description

The PreSonus Quantum ES 2 is built for musicians and creators who want a simple but capable recording interface with strong audio performance and modern workflow features. Its 2x2 configuration makes it ideal for solo recording, podcasting, songwriting, overdubbing, and compact desktop studio setups, while its USB-C connectivity supports high-resolution recording up to 24-bit/192 kHz.

At the core of the interface are two newly redesigned MAX-HD mic preamps that provide up to 75 dB of gain. These digitally controlled analog preamps are designed to offer transparent, low-noise operation, making them especially useful with a wide range of microphones, including gain-hungry dynamic models. Bright LED metering and an illuminated push encoder make it easier to monitor and adjust levels directly from the hardware.

Guitarists and bassists benefit from the front-facing instrument input, which was co-developed with Fender engineers for an input stage tailored to electric guitar and bass recording. Auto Gain simplifies setup by helping users quickly establish proper input levels, while the Universal Control app allows access to key functions such as preamp gain, phantom power, and metering from desktop, tablet, or mobile devices.

PreSonus Quantum ES 2 also includes a perpetual Fender Studio Pro license, giving users a ready-to-record software package alongside the hardware. With custom low-latency drivers, low-noise converters, MIDI connectivity, and a compact footprint, it is a practical solution for creators who need dependable recording quality without adding unnecessary complexity to their workflow.
