Presonus Quantum ES2 USB-C Audio Interface

Take a Sonic Leap with the Quantum ES 2

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 inputs, which were 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.

An Auto Gain button sets the perfect gain level for your microphones and instruments, hassle-free. The loopback audio makes creating monitor and streaming mixes quickly and easily. You can utilize the Universal control app to record straight to your mobile device or remotely control the Quantum ES 2. Professional recording software is included to get your productions started right away.

High-Performance Signal Flow

• Presonus' custom low-latency driver provides exceptionally low audio latencies when recording.
• High-performance converters complete the front end to ensure that you sound your best throughout the entire signal chain.

All-New MAX-HD Mic Preamps

• The Quantum ES 2 features four all-new, next-generation PreSonus MAX-HD preamps that provide transparency and accuracy across the frequency range with +75 dB of gain to maximize the performance of today’s most popular microphones for modern recording and broadcast.
• These proprietary high-definition MAX-HD preamps are transparent, low-noise, and can be digitally controlled from the Studio One DAW or the Universal Control app.
• Discreet phantom power means consistent, full power for microphones that require it, so you’ll get the most from your high-performance studio microphones.

Powerful onboard processing

Revelator io44’s onboard processing lets you polish your recordings and streams with one-click ease, thanks to masterfully crafted presets that give you a professional sound with no expertise required. You’ll also find tools to emulate concert hall reverb, AM radio, or otherworldly invaders to completely transform your sound — and of course, you can create and store your own custom presets for later use. And best of all, this processing happens on the Revelator io44 itself so your customized sound is available whether you connect Revelator io44 to your computer, your tablet, or your phone and won’t use up valuable computer resources when recording or streaming.
