Paired with the included JBL 3 Series studio monitors, cables and stands, you have everything needed to start recording studio-quality tracks right away.

Pristine Preamps Optimized for Modern Mics

At the heart of the Quantum ES4 are four MAX-HD mic preamps, newly redesigned to deliver ultratransparent, low-noise performance. With up to 75dB of gain, these digitally-controlled analog preamps have the headroom to handle today's most sensitive studio mics without clipping or distortion. The expansive gain range ensures you can record everything from delicate vocals to blistering guitar solos with stunning clarity.

Auto Gain Mode Keeps Levels Perfect

One of the Quantum ES4's standout features is its Auto Gain mode. With a single button press, the interface automatically sets ideal gain levels for all connected mics and instruments. Never again will you miss a perfect take due to improper gain staging. Auto Gain takes the guesswork out of recording so you can focus solely on your performance.

Uncompromising Audio Quality at Every Stage

The Quantum ES4's premium audio circuitry, including high-performance 24-bit/192kHz converters, ensures pristine audio quality throughout the entire signal chain. Low-latency drivers eliminate annoying delays during recording and monitoring. From the transparent MAX-HD preamps to the crystal-clear converters, every component is engineered to deliver uncompromised fidelity.

Record Anywhere With the Universal Control App

Thanks to the included Universal Control app, you can record professional-quality audio directly from your phone, tablet or computer whenever inspiration strikes. Adjust critical preamp settings like gain, phantom power and more without interrupting your session. The app's intuitive interface provides seamless wireless control over the ES4 from any location.
