PreSonus Quantum ES4 4x4 24-Bit/192 kHz USB-C Audio Interface

For creators who want full control of their audio production from vision to realization, PreSonus presents the Quantum ES4, a four-input, four-output USB-C interface. Boasting four newly redesigned MAX-HD mic preamps with +75 dB of gain, this interface is perfectly suited for today's most popular microphones, while guitarists and bassists will appreciate the instrument input co-developed with Fender engineers. An Auto Gain button ensures optimal levels for your recordings, while an illuminated push encoder grants flexible control over gain and output volume. With bright LED metering providing visual feedback, high-quality self-produced recording becomes a a way of life. An integrated custom driver guarantees minimal audio latency during recording, and high-performance converters ensure pristine signal handoffs from input to output. Plus, enjoy six months of Studio One+ with access to Studio One Professional Edition and add-ons. Control preamp functions effortlessly via the top panel or through Studio One and the Universal Control app, allowing for seamless gain staging without interrupting your recording session, no matter where inspiration strikes.
