Next-Generation MAX-HD Mic Preamps

At the heart of the Quantum ES4 are four newly designed MAX-HD mic preamps that raise the bar for transparent, low-noise preamplification. These next-gen preamps boast an extraordinary +75dB of gain to effortlessly handle even the most insensitive mics. The digitally controlled analog circuitry ensures ultralow distortion while preserving every nuance. Whether recording vocals, acoustic instruments or drum overheads, these preamps capture all the depth and detail.

Guitar-Focused Design From Fender Experts

In addition to stellar mic pres, the Quantum ES4 features front-panel instrument inputs engineered in collaboration with the tone masters at Fender. These inputs were precisely voiced to authentically represent the sound of plugging into a guitar amp. From clean tones to high-gain crunch, the natural dynamics and harmonics of your guitar or bass rig translate impeccably. An LED ring surrounding the input even provides a cool visual monitoring your levels.

Dial In Perfect Levels With Auto Gain

Quickly get studio-ready tones with the Quantum ES4's Auto Gain feature. Just hit the button, and the interface will automatically set the ideal preamp gain for whichever mic or instrument is connected. This smart gain staging prevents clipping while maximizing headroom for pristine recordings every time. An illuminated push encoder also lets you manually tweak gain and monitor levels using the responsive LED meters.

Extremely Low Latency for Tight Performances 

Thanks to PreSonus' custom low-latency drivers, the Quantum ES4 achieves impressively low monitoring latencies during recording. This tight timing lets you track with confidence, ensuring your performances feel locked in rather than dragging behind the beat. High-performance converters complete the signal chain, delivering 24-bit/192kHz fidelity with minimal noise and coloration. The result is a recording experience that feels as natural as playing live.
