About this item
The culmination of nearly 30 years of design experience, the PreSonus Quantum ES 2 is a 2x2 USB-C desktop audio interface ideal for producers, musicians, and creators looking for high-fidelity audio for the studio or live onstage. The ES 2 features two high-definition MAX-HD mic preamps with +75 dB of gain, ideally suited for today's most popular microphones. Guitarists and bassists will love the front-facing instrument input, which was codeveloped with Fender engineers. High-performance 24-bit / 192 kHz converters let you hear and capture audio with stunning clarity. Use the Quantum ES 2 to record to a Mac/Windows computer or on your iOS/Android phone or tablet.
