Product identity

The Presonus Quantum ES 4 is a 4x4 USB-C desktop audio interface built for producers, musicians and creators who need high-fidelity recording at 24-bit / 192 kHz resolution. It delivers four MAX-HD mic preamps with +75 dB of gain and front-facing Hi-Z instrument inputs co-developed with Fender engineers. Auto Gain sets levels instantly, while loopback audio simplifies streaming mixes and mobile recording via the Universal Control app.

Who it suits and who it does not

This unit suits solo artists and small project studios that require four simultaneous inputs, phantom power and two independent headphone outputs for monitoring. It is not for sessions that need more than four preamp channels, buyers who want built-in DSP effects, or users who require rackmount hardware rather than a desktop form factor.

Deciding specification

The interface provides four combined mic/line/Hi-Z preamps with 24-bit / 192 kHz conversion and +48 V phantom power, giving you the channel count and converter quality that define whether this model fits your workflow.
