Key Features
HIGH PERFORMANCE SIGNAL FLOW. Our custom low-latency driver provides exceptionally low audio latencies when recording, and high-performance converters complete the front end to ensure that you sound your best throughout your entire signal chain.

CO-DEVELOPED WITH FENDER. Built by the best ears in the business, guitarists and bassists will love the instrument input co-developed with Fender engineers – industry experts who designed them specifically for guitar and bass.
PRO RECORDING SOFTWARE ACCESS INCLUDED: Studio One Pro perpetual license.
AUTO GAIN. An Auto Gain button sets the perfect gain level for your microphones and instruments, so you get the perfect take every time.
UNIVERSAL CONTROL APP. Quantum works on any mobile or desktop device, so you’re ready to record whenever inspiration strikes – whether on your phone, tablet, or in your home studio. Critical preamp functions like preamp gain, phantom power, and more can be controlled with the Quantum ES 4’s top panel, or right from Studio One and the Universal Control app, so you can dial in the perfect gain staging without looking away from your recording session.
